Answer:

20368.917N

Explanation:

Frictional force (F) is the product of the Coefficient of friction and the normal reaction.

F = μN

Coefficient of friction, μ = 0.2

Normal reaction = MgCosθ

Mass, m = 12 tonnes = 12 * 1000 = 12000 kg

N = 12000 * 9.8 * cos30

N = 101844.58

F = 0.2 * 101844.58

F = 20368.917N

The vertical deflection of the bar at D can be determined by using the equation for deflection of a beam with a distributed load.

First, we need to calculate the moment of inertia (I) of the rod CB. The moment of inertia for a circular cross-section is given by:

I = (pi/4) * r^4

Where r is the radius of the cross-section. In this case, the cross-sectional area of the rod is 14mm^2, so we can calculate the radius as follows:

14mm^2 = (pi/4) * r^2

r = sqrt((14mm^2 * 4)/pi) = 2.12mm

Now we can calculate the moment of inertia:

I = (pi/4) * (2.12mm)^4 = 39.9mm^4

Next, we need to calculate the elastic modulus (E) of the 6061-T6 aluminum. The elastic modulus for this material is typically around 68.9 GPa (68.9 x 10^9 Pa).

Now we can use the equation for deflection of a beam with a distributed load to calculate the vertical deflection at D:

delta = (5/384) * (w * L^4)/(E * I)

Where delta is the vertical deflection, w is the distributed load, L is the length of the beam, E is the elastic modulus, and I is the moment of inertia. In this case, we have:

delta = (5/384) * (w * (0.8m)^4)/(68.9 x 10^9 Pa * 39.9mm^4)

Simplifying and converting units gives:

delta = (5/384) * (w * (800mm)^4)/(68.9 x 10^9 Pa * 39.9mm^4) = (1.05 x 10^-6) * w

Therefore, the vertical deflection of the bar at D is given by:

delta = (1.05 x 10^-6) * w

Where w is the distributed load in N/m.

These four characteristics, as outlined by Hollnagel (2010), are critical in developing resilient systems that can cope with unexpected situations and adverse external events. Software engineers must educate system developers about these characteristics to develop more resilient systems.

Resilience engineering is about developing adaptable systems that can handle unexpected situations and are able to cope with the effects of adverse external events that might cause system failure. As a software engineer, you need to inform system developers about the following four characteristics that reflect the resilience of an organization, as described by Hollnagel (2010):Maintainability: This characteristic reflects the degree to which a system can be maintained or repaired after it has been damaged. In other words, it assesses the system's ability to remain in good working order or quickly recover from damage. An example of maintainability would be the ability to quickly repair an engine that has been damaged during an accident.Flexibility: This characteristic reflects the degree to which a system can be modified or adapted to cope with changing circumstances. Flexibility is essential for resilience because it enables a system to respond to new challenges and adapt to different circumstances. An example of flexibility would be the ability to change the specifications of a car to adapt to different driving conditions.Redundancy: This characteristic reflects the degree to which a system can continue to function even if some of its components fail. Redundancy is important because it ensures that the system can continue to operate even if one or more components are not working properly. An example of redundancy would be having a backup generator in case the primary generator fails.Responsiveness: This characteristic reflects the degree to which a system can respond to changing circumstances or threats. Responsiveness is important because it enables a system to quickly and effectively respond to unexpected events. An example of responsiveness would be the ability of an air traffic control system to quickly respond to changing weather conditions to ensure the safety of airplanes in the area.

In a vapor compression system used for cooling a home and rejecting energy to the outdoor ambient, the cooling COP (Coefficient of Performance) will decrease as the temperature difference between the indoor air and the ambient air decreases.

The cooling COP is a measure of the cooling efficiency of the system, which is defined as the ratio of the amount of cooling provided to the amount of energy consumed by the compressor. When the temperature difference between the indoor air and the ambient air decreases, the compressor has to work harder to remove the same amount of heat from the indoor air. This results in a decrease in the cooling efficiency of the system and hence a decrease in the cooling COP.
For example, if the outdoor ambient temperature is very high and the indoor air temperature is much lower, the cooling COP will be high

Answer: 240.9 Kpa

Explanation:

Let first changes pressure Gage B from mm of mercury to KPa. That is,

254mm of mercury = 33.86KPa.

To calculate the pressure at C, we need to consider the atmospheric pressure and calculate the absolute pressure of the tank compartment

At gage C, the reading will read P1– P2

Where P1 = absolute pressure

Give that the pressure at B = 254 mm Hg

But (101.33/760) = 33.87 kPa

Where 101.33 = atmospheric pressure

Therefore,

P2 = 101 - 33.87 = 67.13 kPa

P2 = Pa ( pressure at A

Absolute P1 = Patm + Pa= 101 + 207 = 308 kPa abs.

Therefore, Pc = 308 - 67.13

Pc = 240.9Kpa

Therefore, gage C will read 240.9 Kpa if it is connected to compartment 1 but inside compartment 2

A circuit that has had its path broken or "opened" such that current cannot flow is said to have an open circuit. An incomplete circuit is another name for an open circuit.

An open circuit is one in which there is a gap in the circuit's path, preventing the light from turning on. Such a circuit is called an open circuit. Closed circuit: The bulb lights up only when a bulb and wire form a complete path, which starts at one terminal of the electric cell and ends at the other terminal.

The circuit of a lamp with the switch in the OFF position is a typical illustration of an open circuit. The circuit of a lamp with the switch turned on serves as an illustration of a closed switch.

Answer:

Weight Percentage of Ash = 3.4

Explanation:

Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.

To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?

Solution -

Given that,

Coal Burned Rate = 10,000 kg/hr

                              = \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)

                              = 166.6666 kg/min

⇒Coal Burned Rate = 166.6666 kg/min

Now,

Given that,

Ash content in coal = 21 %

⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min

                                             = 34.9999 ≈ 35 kg/min

⇒Ash in (coal that burned) = 35 kg/min

Now,

We know,

Density of water = 1000 kg/m³

Now,

Water flow Rate = \(1\frac{m^{3} }{min} * density\)

                           = 1000 kg/min

⇒Water flow Rate = 1000 kg/min

Now,

Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min

                                                                           = 1035 kg/min

⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min

So,

Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100

                                            = (35 ÷ 1035) × 100

                                            = 3.38 ≈ 3.4

∴ we get

Weight Percentage of Ash = 3.4

The synchronous impedance, Zs, can be calculated as (1040V/200A) = 5.2 ohms. The synchronous reactance, Xs, is √(Zs² - R²) = √(5.2² - 0.2²) = 5.199 ohms.

For 0.8 pf lagging:

The voltage regulation is Vr(lag) =

[(√(Ea² - V²)/V)x(0.8) + (Xs/V)x(0.6)]*100 = [(√(1040² - (3000/√3)²)/(3000/√3))x(0.8) + (5.199/(3000/√3))x(0.6)]*100

≈ 6.91%.

For 0.8 pf leading:

The voltage regulation is Vr(lead) =

[(√(Ea² - V²)/V)x(0.8) - (Xs/V)x(0.6)]*100

≈ -3.52%.

Phasor Diagrams: In both cases, Ea, V, I, and Zs are represented by phasors. For 0.8 pf lagging, the current phasor lags behind the voltage, and for 0.8 pf leading, it leads the voltage.

The voltage regulation is the difference in magnitude between Ea and V.

Answer:

\( \therefore \) The power output of the draw-works motor is 4.36 hp

Explanation:

Given that,

As the problem given, the cable is tied of the top on the oil rig and it wraps around the lower pulley and the top pulley. So, we will be using the formula below:

Differentiate it but with respect to the time. Therefore,

Thus,

Thus, the power output should be

\( P = Fv = \bigg(\frac{600}{2}\bigg) \cdot 8 = 2400 \ lb \cdot ft/s = \frac{2400}{550} = 4.36 \ hp \)

\( \therefore \) The power output of the draw-works motor is 4.36 hp

To solve for the current \(I_2\) through resistor \(R_2\), we need to use Kirchhoff's current law (KCL) at the node where \(R_1\), \(R_2\), and \(R_y\) meet.

By KCL, the current flowing into this node must be equal to the current flowing out of the node. We can express this as:

\(I_1\) = \(I_2\) + \(l_y\)

Where I1 is the current flowing from the positive terminal of the \(V_a\) battery, \(l_y\) is the current flowing through resistor \(R_y\), and \(I_2\) is the current flowing through resistor \(R_2\).

We can also apply Kirchhoff's voltage law (KVL) to the outer loop of the circuit, which includes the Va and Vb batteries and  \(R_1\) and \(R_2\) resistors. This gives us:

\(V_a\) - \(I_1\)\(R_1\) - \(I_2\) \(R_2\) - \(V_b\) = 0

We can solve these two equations for \(I_2\), which gives us:

\(I_2\) = (\(V_a\) - \(V_b\) + \(l_y\)*\(R_y\))/\(R_2\)

This expression for \(I_2\) in terms of Va, Vb, \(R_1\), \(R_2\), and \(R_y\) shows that the current through \(R_2\) depends on the voltages of the two batteries, the values of the resistors, and the current through \(R_y\).

Complete question:
