b) For a triplex system with a component failure rate of 35000 flight-hours per failure, what is the "fail-active". rate, in flight hours per failure. Assume all failures are independent.
Answers
a) In a duplex system with a component failure rate of 1 per 100,000 flight hours, the 'fail-safe' rate, in flight hours per failure, would be 100,000 flight hours per failure. This means that, on average, one failure is expected to occur every 100,000 flight hours.
b) In a triplex system with a component failure rate of 35,000 flight hours per failure, the "fail-active" rate, in flight hours per failure, would also be 35,000 flight hours per failure. This indicates that, on average, one failure is expected to occur every 35,000 flight hours.
a) In a duplex system, there are two redundant components working in parallel. The fail-safe rate refers to the ability of the system to continue operating safely in the event of a single component failure. Since the failure of each component is independent, the overall failure rate is the inverse of the individual failure rate. Therefore, the fail-safe rate would be 100,000 flight hours per failure, indicating that the system can sustain normal operation for an average of 100,000 flight hours between failures.
b) In a triplex system, there are three redundant components working in parallel. The fail-active rate represents the system's ability to remain active and operational even in the presence of a single component failure. Similar to the duplex system, the failure rate is calculated as the inverse of the individual failure rate. Thus, the fail-active rate would be 35,000 flight hours per failure, meaning that the system can continue functioning normally for an average of 35,000 flight hours before experiencing a failure.
It is important to note that these failure rates are based on average probabilities and provide a measure of reliability for the respective systems. Actual failure occurrences may vary, and additional factors such as maintenance practices and system design should also be considered in assessing overall system reliability.

Which device converts solar radiation to thermal energy?
Answers
A solar thermal collector is the device that converts solar radiation into thermal energy. These collectors are designed to efficiently absorb sunlight and transfer the generated heat to a fluid, usually water or air.
This heated fluid can then be used for various applications such as space heating, domestic hot water, or industrial processes.There are two main types of solar thermal collectors: flat-plate collectors and concentrating collectors. Flat-plate collectors are the most common and consist of a flat, dark surface that absorbs sunlight and transfers the heat to a fluid flowing through tubes attached to the plate. These collectors are simple, durable, and suitable for low to moderate temperature applications.Concentrating collectors, on the other hand, use mirrors or lenses to focus sunlight onto a small area, achieving higher temperatures. These collectors are more efficient but require precise tracking of the sun and are typically used in large-scale power plants or industrial processes.In summary, solar thermal collectors are the devices that convert solar radiation into thermal energy, with flat-plate collectors and concentrating collectors being the main types. These collectors are essential components of solar thermal systems and contribute to the efficient utilization of renewable energy from the sun.

A construction company distributes its products by trucks loaded at its loading station. A backacter in conjunction with trucks are used for this purpose. If it was found out that on an average of 12 trucks per hour arrived and the average loading time was 3 minutes for each truck. A truck must queue until it is loaded. The backacter’s daily all-in rate is GH¢ 1000 and that of the truck is GH¢ 400.
a) Compute the operating characteristics: L, Lq, W, Wq, and P.
b) The company is considering replacing the backacter with a bigger one which will have an average service rate of 1.5 minutes to serve trucks waiting to have their schedules improved. As a manager, would you recommend the new backacter if the daily all-in rate is GH¢ 1300.
c) The site management is considering whether to deploy an extra backwater to assist the existing one. The daily all-in-rate and efficiency of the new backwater is assumed to be the same as that of the existing backwater. Should the additional backwater be deployed?
Answers
Answer:
a) \(L = 1.5\)
\(L_q = 0.9\)
\(W = \dfrac{1 }{8 } \, hour\)
\(W_q = \dfrac{3}{40 } \, hour\)
\(P = \dfrac{3}{5 }\)
b) The new backacter should be recommended
c) The additional backacter should not be deployed
Explanation:
a) The required parameters are;
L = The number of customers available
\(L = \dfrac{\lambda }{\mu -\lambda }\)
μ = Service rate
\(L_q\) = The number of customers waiting in line
\(L_q = p\times L\)
W = The time spent waiting including being served
\(W = \dfrac{1 }{\mu -\lambda }\)
\(W_q\) = The time spent waiting in line
\(W_q = P \times W\)
P = The system utilization
\(P = \dfrac{\lambda }{\mu }\)
From the information given;
λ = 12 trucks/hour
μ = 3 min/truck = 60/3 truck/hour = 20 truck/hour
Plugging in the above values, we have;
\(L = \dfrac{12 }{20 -12 } = \dfrac{12 }{8 } = 1.5\)
\(P = \dfrac{12 }{20 } = \dfrac{3}{5 }\)
\(L_q = \dfrac{3}{5 } \times \dfrac{3}{2 } = \dfrac{9}{10 } = 0.9\)
\(W = \dfrac{1 }{20 -12 } = \dfrac{1 }{8 } \ hour\)
\(W_q = \dfrac{3}{5 } \times \dfrac{1}{8 } = \dfrac{3}{40 } \, hour\)
(b) The service rate with the new backacter = 1.5 minutes/truck which is thus;
μ = 60/1.5 trucks/hour = 40 trucks/hour
\(P = \dfrac{12 }{40 } = \dfrac{3}{10}\)
\(W = \dfrac{1 }{40 -12 } = \dfrac{1 }{38 } \, hour\)
\(W_q = \dfrac{3}{10 } \times \dfrac{1}{38 } = \dfrac{3}{380 } \, hour\)
λ = 12 trucks/hour
Total cost = \(mC_s + \lambda WC_w\)
m = 1
\(C_s\) = GH¢ = 1300
\(C_w\) = 400
Total cost with the old backacter is given as follows;
\(1 \times 1000 + 12 \times \dfrac{1}{8} \times 400 = \$ 1,600.00\)
Total cost with the new backacter is given as follows;
\(1 \times 1300 + 12 \times \dfrac{1}{38} \times 400 = \$ 1,426.32\)
The new backacter will reduce the total costs, therefore, the new backacter is recommended.
c)
Here μ = 3 min/ 2 trucks = 2×60/3 truck/hour = 40 truck/hour
\(\therefore W = \dfrac{1 }{40 -12 } = \dfrac{1 }{38 } \, hour\)
Total cost with the one backacter is given as follows;
\(1 \times 1000 + 12 \times \dfrac{1}{8} \times 400 = \$ 1,600.00\)
Total cost with two backacters is given as follows;
\(2 \times 1000 + 12 \times \dfrac{1}{38} \times 400 = \$ 2,126.32\)
The additional backacter will increase the total costs, therefore, it should not be deployed.

The dual problem of a linear programming problem can be found by flipping the inequality signs and re-assigning the objective function as a constraint.
Given the following linear programming problem min 4x1 - 3 x2 subject to 3x1 - x2 ≤ 6 5x1 - 4x2 ≥ 8 x1 - 6x2 =5 x1, x2 ≥ 0To find the dual of the problem, the following steps can be taken:
Step 1: Flip the problem The first step in finding the dual problem is to flip the inequality signs of the constraint of the original problem. The constraints of the original problem are as follows:3x1 - x2 ≤ 65x1 - 4x2 ≥ 8x1 - 6x2 = 5Flipping the inequality signs of the above equations results in the following:3x1 - x2 ≥ 65x1 - 4x2 ≤ 8x1 - 6x2 = 5
Step 2: Re-assign the objective The next step is to re-assign the objective function of the original problem as a constraint. That is, the coefficients of the original objective function are used as constraints in the dual problem. Thus, for the given problem,

Answer:
SECTION LEARNING OBJECTIVES
By the end of this section, you will be able to do the following:

Static Friction and Kinetic Friction
Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.
There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.
Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.
Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.
The acceleration of a particle is defined by the relation a = 9 − 3t2, where a and t are expressed in ft/s2 and seconds, respectively. The particle starts at t = 0 with v = 0 and x = 5 ft. Determine (a) the time when the velocity is again zero, (b) the position and velocity when t = 4 s, (c) the total distance travelled by the particle from t = 0 to t = 4 s.
Answers
(a) To find the time when the velocity is again zero, we set the velocity equal to 0 and solve for t:
0 = v0 + at = 9t - 3t^3
Solving for t, we find that t = ±1.
(b) To find the position and velocity when t = 4 s, we first need to find the velocity equation by integrating the acceleration equation:
v = ∫a = ∫(9 - 3t^2)dt = 9t - t^3 + C
Using the initial condition v(0) = 0, we find C = 0 and
v(t) = 9t - t^3
Next, we integrate v(t) to find the position equation:
x = ∫v = ∫(9t - t^3)dt = 3t^2 - t^4 + C
Using the initial condition x(0) = 5, we find C = 5 and
x(t) = 3t^2 - t^4 + 5
Evaluating x(t) and v(t) at t = 4 s, we have:
x(4) = 3(4^2) - 4^4 + 5 = 51
v(4) = 9(4) - 4^3 = -36
(c) To find the total distance travelled by the particle from t = 0 to t = 4 s, we need to find the distance between the initial and final positions:
d = x(4) - x(0) = 51 - 5 = 46 ft
So the total distance travelled by the particle from t = 0 to t = 4 s is 46 ft.

An isolated charged soap bubble of radius R 0 = 6. 95 cm is at a potential of V 0 = 307. 0 volts. If the bubble shrinks to a radius that is 39. 0 % of the initial radius, by how much does its electrostatic potential energy U change? Assume that the charge on the bubble is spread evenly over the surface, and that the total charge on the bubble remains constant
Answers
The electrostatic potential energy U changes by -0.39307 J.
The electrostatic potential energy of a system is given by the equation U = 1/2 * QV, where Q is the total charge on the system and V is the potential difference.
If the radius of the bubble shrinks by 39%, the potential difference will also shrink by the same amount, thus changing the potential energy. To calculate this change, we can use the equation: U = 1/2 * QV_initial - 1/2 * QV_final.
Since Q is constant, the change in potential energy is simply the change in V. Hence, U = 1/2 * Q(V_initial - (V_initial * 0.39)) = -0.39307 J

What is LER?In agriculture, the term "land equivalent ratio" refers to the proportion of land area needed for monoculture (single-crop farming) to yield the same amount of yield as intercropping (polyculture).
The FAO defines the land equivalent ratio (LER) as the ratio of the area used for sole cropping to the area used for intercropping in order to produce an equal amount of yield at the same management level. The result is the sole-crop yields multiplied by the sum of the intercropped yield fractions.
We must use a chord, so I'm assuming that it is 0.045 m in length.
The formula provides the Area.
Area = span × chord
Area = 0.245 × 0.045
Area = 0.011 m²

Mechanical advantage refers to the ratio of force output to force input in a given system. It measures how much easier a machine can make a task by amplifying force.
For example, a lever can be used to lift a heavy object with less effort. The mechanical advantage of a lever is calculated by dividing the distance from the fulcrum to the input force by the distance from the fulcrum to the output force.
Another example of mechanical advantage is the use of a pulley system. A pulley system can reduce the amount of force needed to lift a heavy object by distributing the weight over several ropes and pulleys. The mechanical advantage of a pulley system is determined by counting the number of ropes or sections of rope supporting the load.

determine the speed v0 and launch angle with
which the point guard should throw the ball
Answers
In a basketball game, point guard A intends the speed as 47.76 ft/sec, and the launch angle will be 41.084°.
What is the projectile motion?The projectile motion is given as the motion of the object in the curved path near the earth's surface. The throwing of the ball will follow the projectile motion.
The missing image is attached below.
The given game situation consists of:
Velocity of shooting guard (vs) = 12 ft/sec.
Distance from B to C (sc) = 20 ft
Final height to catch the ball, 7 ft
The total distance to cover from B to C = 60 ft
Time is taken to reach B to C = Distance/Speed
Time to reach B to C = 20ft/12ft/sec
Time to reach B to C = 1.667 sec.
The time taken to cover the horizontal distance:
Distance = Velocity * Time
60³ = v₀cosθ * distance/time
60³ = v₀cosθ * 20/12
v₀cosθ = 36 ft/sec
The vertical movement can be given where, g = 32.2 ft/sec²:
s = s₀ + v₀sinθ * time + 1/2 -g time²
7 = s + v₀sinθ * 20/12 - 1/2 32.2 ft/sec² * (20/12)²
v₀sinθ = 31.3875 ft/sec
\(\rm v_0 =\sqrt{v_0sin\theta^2\;+\;v_ocos\theta^2}\)
Substituting the values:
v₀ = 47.76 ft/sec
The launch angle for the ball will be:
tanθ = v₀sinθ/v₀cosθ
tanθ = 31.3875/36
tanθ = 0.871
θ = 41.084°
Thus, the speed v₀ of the ball will be 47.76 ft/sec, and the launch angle will be 41.084°.

in this lab, the current for a bjt (bipolar junction transistor) constant current sink was determined by the voltage and resistance in
Answers
In this lab, the current for a BJT (Bipolar Junction Transistor) constant current sink is determined by the voltage and resistance. Here's an explanation that includes the terms "resistance," "constant," and "voltage":
1. Resistance (R): This is the opposition to the flow of electric current in a circuit, measured in ohms (Ω).
2. Constant: In the context of a BJT constant current sink, this refers to maintaining a stable current flow through the transistor, regardless of voltage variations across it.
3. Voltage (V): This is the electric potential difference between two points in a circuit, measured in volts (V).
To determine the current for a BJT constant current sink, you can use Ohm's Law, which states:
I = V / R
Where I is the current, V is the voltage, and R is the resistance.
In the lab, a specific voltage (V) and resistance (R) were applied to the BJT. As the current (I) is directly proportional to the voltage and inversely proportional to the resistance, it can be calculated using the given values of voltage and resistance. The BJT is designed to maintain a constant current flow, despite any changes in the voltage across the transistor. This ensures that the current remains stable, making the BJT a reliable constant current sink.

as the angle of the ramp is increased the force parallel increases /decreases / remains the same
Answers
As the angle of the ramp is increased, the force parallel increases. Hence, option (a) can be considered as the correct answer.
When the angle of a ramp is increased, the force parallel to the ramp, also known as the parallel component of the gravitational force, does increase. This is because the component of gravity acting parallel to the ramp increases with the angle. However, it's important to note that the total gravitational force acting on an object remains constant regardless of the angle of the ramp.As the angle of the ramp increases, the force required to push or pull an object up the ramp against gravity increases. This is due to the increase in the vertical component of the gravitational force, which opposes the motion up the ramp. The parallel force required to overcome this increased vertical force also increases.

. to provide some perspective on the dimensions of atomic defects, consider a metalspecimen that has a dislocation density of 104 mm-2. suppose that all the dislocationsin 1000 mm3 (1 cm3) were somehow removed and linked end to end. how far (in miles)would this chain extend? now suppose that the density is increased to 1010 mm-2 bycold working. what would be the chain length of dislocations in 1000 mm3 of material?
Answers
For a dislocation density of 10^4 mm^-2, the chain would extend 1.24 miles. For a density of 10^10 mm^-2, the chain would extend 124,274 miles.
1. Calculate total dislocations: Dislocation density x Volume = 10^4 mm^-2 x 1000 mm^3 = 10^7 dislocations
2. Estimate the length of one dislocation: Consider 1 mm as an average dislocation length
3. Calculate total length of dislocations: 10^7 dislocations x 1 mm/dislocation = 10^7 mm
4. Convert length to miles: 10^7 mm x (1 m/1000 mm) x (1 km/1000 m) x (1 mile/1.609 km) ≈ 1.24 miles
5. Repeat steps 1-4 for a density of 10^10 mm^-2: 10^10 mm^-2 x 1000 mm^3 = 10^13 dislocations, total length ≈ 124,274 miles.
Therefore the chain would extend 1.24 miles.

C. Fulcrum
D. Spring Scale
Answers
Definition:
the point on which a lever rests or is supported and on which it pivots.
Sarah is on a see saw with her friend. The pivot or fixed point where the bar is free to move is called the Fulcrum. Hence, option C is correct.
What is Fulcrum?The support or base that a lever rotates on in order to lift or move anything. The verb fulcire, which means "to prop," is the root of the Latin term fulcrum, which means "bedpost."
The term "fulcrum" was first used in the 17th century to describe the pivotal point of a lever or other similar mechanism, such as the oar of a boat.
The Fulcrum line of road bike wheels offers lightweight and durable wheelsets for every circumstance, course, discipline, and price range. From the top-tier full carbon aero wheels to the high performance aluminum line, Fulcrum offers the perfect wheel to match your performance.
Thus, option C is correct.
