Answers
To perform an electrical analysis of the given charger prototype circuit, the Thevenin equivalent circuit is derived by determining the Thevenin voltage and the Thevenin resistance.
By analyzing the equivalent circuit, the maximum power transfer to the load can be calculated using the concept of the maximum power transfer theorem.
i) To find the Thevenin equivalent circuit, the network shown in Figure 1 is reduced to a simplified equivalent circuit that represents the behavior of the original circuit when viewed from the load terminals AB. The Thevenin voltage (V_th) is the open-circuit voltage across AB, and the Thevenin resistance (R_th) is the equivalent resistance as seen from AB when all the independent sources are turned off. In this case, R1, R2, and R4 are in series, so their total resistance is R_total = R1 + R2 + R4 = 40 + 30 + 60 = 130 ohms. The Thevenin voltage is calculated by considering the voltage division across R4 and R_total, which gives V_th = V * (R4 / R_total) = 20 * (60 / 130) = 9.23 V. Therefore, the Thevenin equivalent circuit for the given network is a voltage source of 9.23 V in series with a resistance of 130 ohms.
ii) To determine the maximum power that can be transferred to the load from the circuit, we use the maximum power transfer theorem. According to the theorem, the maximum power is transferred from a source to a load when the load resistance (RL) is equal to the Thevenin resistance (R_th). In this case, R_th is 130 ohms. Therefore, to achieve maximum power transfer, the load resistance should be set to RL = 130 ohms. The maximum power (P_max) that can be transferred to the load is calculated using the formula P_max = (V_th^2) / (4 * R_th) = (9.23^2) / (4 * 130) = 0.155 W (or 155 mW). Hence, the maximum power that can be transferred to the load from the circuit is approximately 0.155 W.

The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s2
Find the total time required for the police car to over take the automobile.
Answer:
15.02 sec
Explanation:
The total time required for the police car to overtake the automobile is related to the distance covered by both cars which is equal from instant point of abreast.
So; we can say :
\(D_{pursuit} =D_{police}\)
By using the second equation of motion to find the distance S;
\(S= ut + \dfrac{1}{2}at^2\)
\(D_{pursuit} = (15.65 *12 )+(15.65 (t)+ (\dfrac{1}{2}*(-3.05)t^2)\)
\(D_{pursuit} = (187.8)+(15.65 \ t)-0.5*(3.05)t^2)\)
\(D_{pursuit} = (187.8+15.65 \ t-1.525 t^2)\)
\(D_{police} = ut _P + \dfrac{1}{2}at_p^2\)
where ;
u = 0
\(D_{police} = \dfrac{1}{2}at_p^2\)
\(D_{police} = \dfrac{1}{2}*(1.96)*(t+12)^2\)
\(D_{police} = 0.98*(t+12)^2\)
\(D_{police} = 0.98*(t^2 + 144 + 24t)\)
\(D_{police} = 0.98t^2 + 141.12 + 23.52t\)
Recall that:
\(D_{pursuit} =D_{police}\)
\((187.8+15.65 \ t-1.525 t^2)= 0.98t^2 + 141.12 + 23.52t\)
\((187.8 - 141.12) + (15.65 \ t - 23.52t) -( 1.525 t^2 - 0.98t^2) = 0\)
= 46.68 - 7.85 t -2.505 t² = 0
Solving by using quadratic equation;
t = -6.16 OR t = 3.02
Since we can only take consideration of the value with a positive integer only; then t = 3.02 secs
From the question; The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit;
Therefore ; the total time required for the police car to over take the automobile = 12 s + 3.02 s
Total time required for the police car to over take the automobile = 15.02 sec

Answer:

Explanation:
The resistor voltage has the same phase as the circuit current. There is no phase difference.
Answer:
0° (zero degree)Explanation:
the difference in pjase between the current and resistor voltage of the given 150.0 ohm, 300.0 ohm and 200.0 ohmA railroad runs form city A to city B, a distance of 800km, through mountainous terrain. The present one-way travel time (including time at intermediate yards) is 20 hours, and the rail freight rate is $20 per ton. There is a truck service that competes with the railroad, running over a roughly parallel road for approximately the same distance, at an average speed of 48km per hour and a rate of $30 per ton. A new highway is planned to replace the existing roads; it is expected that most of the traffic will be trucks (auto usage is expected to be negligible). The performance function of the new facility is t_T = t_0 + bV_T, where V_T is the flow in trucks per hour, t_0 = 10 hours, b = 0.08 hour per truck per hour. The railroad's estimate of the demand function is: V_T/V_R = a_0(t_r/t_R)^a_1 (c_T/c_R)^a_2 where t_T and t_R are the trip times (in hours) by truck and rail, respectively, c_T and c_R are the corresponding rates, V_T and V_R are the corresponding flows and a_0, a_1 and a_2 are parameters. The total demand is likely to remain constant at V_TOT = 200 tons per hour. The rail system is utilized at only a fraction of capacity, so its performance function is flat (travel time is constant, independent of volume). If a_0 = 1, a_1 = -1 and a_2 = -2, find the present flows of freight by truck and rail. Make an estimate of the equilibrium flows if the new highway were built. With the new highway built, what would the equilibrium flow be in each of the following two cases: if the railroad dropped its rate to $15 per ton? if truckers were taxed $5 per ton to help pay for the new highway?

Explanation:
Average setup time on a certain production machine is 5.0 hr. Average batch size is 52 parts, and average operation cycle time is 4.2 min. The reliability of this machine is characterized by mean time between failures of 37 hr and a mean time to repair of 55 min.
(a) If availability is ignored, what is the average hourly production rate of the machine.
(b) Taking into account the availability of the machine, determine its average hourly production rate.
(c) Suppose that availability only applied during the actual run time of the machine and not the setup time. Determine the average hourly production rate of the machine under this scenario.
Answers
(a) The machine's average hourly production rate without considering availability is 6.02 parts/hr.
(b) The machine's average hourly production rate, taking into account availability, is 6.17 parts/hr.
(c) The machine's average hourly production rate when only available during run time is 5.71 parts/hr.
How to solve calculations on a production machine?(a) To calculate the average hourly production rate of the machine without considering availability, we need to first calculate the total time it takes to produce a batch of 52 parts.
Total time = (setup time) + (operation time per part x batch size)
Total time = 5.0 hr + (4.2 min/part x 52 parts)/60 min/hr
Total time = 5.0 hr + 3.64 hr
Total time = 8.64 hr
Average hourly production rate = Batch size / Total time
Average hourly production rate = 52 parts / 8.64 hr
Average hourly production rate = 6.02 parts/hr
Therefore, the average hourly production rate of the machine without considering availability is 6.02 parts/hr.
(b) To calculate the average hourly production rate of the machine taking into account availability, we need to first calculate the machine's availability using the mean time between failures (MTBF) and mean time to repair (MTTR) values.
Availability = MTBF / (MTBF + MTTR)
Availability = 37 hr / (37 hr + 0.92 hr)
Availability = 0.975 or 97.5%
Now we can calculate the total time that the machine is available for production:
Available time = Total time x Availability
Available time = 8.64 hr x 0.975
Available time = 8.42 hr
Average hourly production rate = Batch size / Available time
Average hourly production rate = 52 parts / 8.42 hr
Average hourly production rate = 6.17 parts/hr
Therefore, the average hourly production rate of the machine taking into account availability is 6.17 parts/hr.
(c) If availability only applies during the actual run time of the machine and not the setup time, we need to adjust the available time calculation:
Available time = (operation time per part x batch size) / 60 min/hr x Availability
Available time = (4.2 min/part x 52 parts) / 60 min/hr x 0.975
Available time = 4.11 hr
Total time = Available time + setup time
Total time = 4.11 hr + 5.0 hr
Total time = 9.11 hr
Average hourly production rate = Batch size / Total time
Average hourly production rate = 52 parts / 9.11 hr
Average hourly production rate = 5.71 parts/hr
Therefore, the average hourly production rate of the machine taking into account availability only during run time is 5.71 parts/hr.

A single-piece cylinder head installed on an inline six-diesel engine will cover _______ cylinder pack(s).
Answers
A single-piece cylinder head installed on an inline six-diesel engine will cover 6 cylinder pack(s).Explanation:A cylinder head is the section of an engine block that covers the cylinders.
It separates the head from the block of the engine. It can house the camshaft and valves and provides a sealing surface for the head gasket. A cylinder head is an engine part that sits on top of the cylinder block and seals the combustion chamber. It's made up of several components, including exhaust and intake valves, springs, and retainers, as well as the rocker arm assembly. It's bolted to the engine block using head bolts.Cylinder heads are present in inline-six diesel engines. They're called inline six engines since all six cylinders are arranged in a line. The inline-six engine's most significant benefit is its length, which is only a little longer than a four-cylinder engine.
This is a significant advantage for automotive designers since it allows them to put the engine in tight spaces while maintaining a longer stroke for improved torque.Cylinder heads come in a variety of shapes and sizes, but most are designed to cover a single cylinder pack. As a result, a single-piece cylinder head installed on an inline-six diesel engine would cover 6 cylinder packs, one for each cylinder.

Segments ab and cd of the assembly are solid circular rods, and segment bc is a tube. If the assembly is made of 6061-t6 aluminum, determine the displacement of end d with respect to end a.
Answers
The displacement of end D with respect to end A is \(-0.488 \times 10^{-3}\;m\)
Given the following data:
Length = 435 mm to m = 0.435 meter.Modulus of elasticity = 68.9 GPa.Radius A = 20 mm to m = 0.03 meter.Inner radius BC = 30 mm to m = 0.03 meter.Outer radius BC = 40 mm to m = 0.04 meter.Force A = 10 kN.Force B = 15 kN.To determine the displacement of end D with respect to end A:
How to calculate the displacement.First of all, we would do a sectional cut of the circular rods at point A and then determine the sum of forces acting on it:
\(\sum F=0\\\\ 10000+N_1=0\\\\N_1 = -10000\;N\)
Mathematically, the displacement of a circular rod is given by this formula:
\(d = \frac{NL}{AE}\)
Where:
N is the normal force.L is the length.A is the area.E is the modulus of elasticity.Substituting the given parameters into the formula, we have;
\(d_1 = \frac{-10000 \times 0.435}{\frac{3.142 \times 0.02^2}{4} \times 68.9 \times 10^9} \\\\d_1 = \frac{-4350}{0.0003142 \times 68.9 \times 10^9}\\\\d_1 =-0.201 \times 10^{-3}\;meter\)
For section cut BC:
\(\sum F=0\\\\ 10000-20000+N_2=0\\\\N_2 = 10000\;N\)
\(radius = outer\;radius^2 - inner\;radius^2\\\\radius = 0.04^2 -0.03^2=0.0007\;m\)
\(d_2 = \frac{10000 \times 0.435}{\frac{3.142 \times 0.0007^2}{4} \times 68.9 \times 10^9} \\\\d_2 = \frac{4350}{0.00054985 \times 68.9 \times 10^9}\\\\d_2 =0.115 \times 10^{-3}\;meter\)
For section cut D:
\(\sum F=0\\\\ -20000-N_3=0\\\\N_3 =- 20000\;N\)
\(d_3 = \frac{-20000 \times 0.435}{\frac{3.142 \times 0.02^2}{4} \times 68.9 \times 10^9} \\\\d_3 = \frac{-8700}{0.0003142 \times 68.9 \times 10^9}\\\\d_3 =-0.402 \times 10^{-3}\;meter\)
For the total displacement:
The total displacement is equal to the displacement of end D with respect to end A.

Plot y(n) which is achieved by y(n) = x(n) ⋆ h(n).x(n) = {1, 1, 1, 1, 1}h(n) = {1, 1, 1}By applying convolution, we get y (n) = x(n) ⋆ h(n) = {1, 2, 3, 3, 3, 2, 1}(b) Solve the above problem analytically by hand and determine if the two outputs are the same.
x(n) = {1, 1, 1, 1, 1}h(n) = {1, 1, 1}y(n) = x(n) ⋆ h(n)So, $$y(n) = \sum_{k=-\infty}^{\infty} x(k)h(n-k)$$The non-zero terms in the summation will be when k = 0, 1, 2, 3, 4. Then,$$y(n) = \sum_{k=0}^{4} x(k)h(n-k)$$$$y(n) = \sum_{k=0}^{4} h(k) x(n-k)$$Substituting the given values of x(n) and h(n), we have $$y(n) = (1 * 1) + (1 * 1) + (1 * 1) + (1 * 1) + (1 * 1)$$$$y(n) = 1 + 1 + 1 + 1 + 1$$$$y(n) = 5$$The first and the last samples in y(n) occur when h(n) overlaps with the endpoints of x(n), which are 0 and 4. Hence, the duration of y(n) is 5 samples.
The convolution output of x(n) and h(n) matches with the result obtained in the above solution.

When the process is in control but does not meet specification which type of error is it?
Answers
When the process is in control but does not meet specification, it is referred to as a special cause error.
What is the term for a process in control but not meeting specification?In statistical process control, a process is considered to be in control when it operates within the defined limits and shows only random variations. However, when a process is in control but does not meet the desired specifications, it indicates the presence of a special cause error.
Special cause errors are attributed to specific factors or events that cause the process to deviate from the expected outcome. These errors are typically unpredictable and require investigation and corrective action to bring the process back within the desired specifications.
