It is not safe to operate the motor with a 10-hp shaft load.

Explanation :
Solution-
First, determine the rated speed and current of the motor:
Rated speed = 850 r/min
Rated current = 500 V / (0.1414 ohms + 0.0412 ohms + 0.0189 ohms) = 30.22 A
Next, determine the speed and current for a 10-hp shaft load:
Speed = 1700 r/min
Current = 10 hp / (75 hp * 0.902) = 0.1343 A
Finally, determine whether it is safe to operate the motor with the 10-hp shaft load using the magnetization curve. we can see that the current at 1700 r/min is 0.1264 A, which is less than the current for the 10-hp shaft load (0.1343 A).

All of the listed processes can increase the deformation resistance of steel. Tempering can improve the toughness and reduce brittleness of the steel, but does not necessarily increase its strength.

Hot working, such as rolling or forging at high temperatures, can refine the grain structure of the steel and increase its strength. Adding alloying elements, such as carbon, manganese, or chromium, can significantly increase the strength and hardness of the steel. Hardening, such as quenching and tempering, can also increase the strength and hardness of the steel by transforming its microstructure.

We are required to determine the operating time per year in the given case. Here's how we can solve this problem:A plant engineer is evaluating the purchase of two possible motors.

Both motors are each rated at 125hp, but have different efficiencies and purchase costs. The less expensive motor has an initial purchase cost of $1000 and is 88% efficient. The more expensive motor has an initial purchase cost of $1500 and is 92% efficient.

The plant pays

$0.07/kW⋅h,

which reflects the cost if the total electricity costs are paid at the end of year 10. The annual effective interest rate over a 10-year period of life is 10%.The net present value (NPV) formula to compare two different options of investment (purchase of a motor in this case) is

NPV = C1 + C2/(1+i)² + C3/(1+i)³ + ….. - CI/(1+i)n

where,Ci = Cash inflow/outflow for year i (year 0 is usually the present year)

i = Discount rate

N = life of the investment

As both the options have the same net present value, we can assume that the net present value for both the options would be equal.

Calculating the net present value of Option 1 (Less expensive motor):Initial purchase cost

= $1000Operating cost (electricity)

= (125hp × 0.746 kW/hp) × (1/0.88 - 1) × 365 × 24 h/yr × $0.07/kWh =$6158.01

Net Present Value of Option

1 = -$1000 - $6158.01/(1+0.10)²

= -$4641.63

Calculating the net present value of Option 2 (More expensive motor):Initial purchase cost

= $1500O

perating cost (electricity)

= (125hp × 0.746 kW/hp) × (1/0.92 - 1) × 365 × 24 h/yr × $0.07/kWh

= $5337.69Net Present Value of Option 2

= -$1500 - $5337.69/(1+0.10)² = -$4665.

14Now we can use the following equation:Operating time per year

= (annual electricity cost)/(125hp × 0.746 kW/hp × (1/η - 1))where,η

= Efficiency of the motorUsing the above equation for both the options, we get:Operating time per year for Option 1

= $6158.01/(125hp × 0.746 kW/hp × (1/0.88 - 1))

= 614.36 h/yrOperating time per year for Option 2

= $5337.69/(125hp × 0.746 kW/hp × (1/0.92 - 1))

= 690.47 h/yr

Therefore, the most nearly operating time per year is (C) 690 h/yr.

The wired networking standard that specifies the order in which data is sent through the network is Ethernet.

Ethernet is a widely used wired networking standard that defines the protocols and specifications for data transmission over a local area network (LAN). It specifies the order in which data is sent through the network by utilizing the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) algorithm.

The CSMA/CD algorithm ensures that multiple devices connected to an Ethernet network can share the same communication medium without interfering with each other. Before transmitting data, a device using Ethernet listens to the network to detect if it is clear to send data. If the network is busy, it waits for an opportune moment. Once the network is clear, the device sends the data, constantly monitoring for collisions. If a collision occurs (when two or more devices transmit data simultaneously), they stop transmitting, wait for a random period of time, and then retry.

By following this protocol, Ethernet ensures orderly and efficient data transmission within the network, minimizing collisions and maximizing data throughput. It has become the de facto standard for wired local area networks due to its reliability, scalability, and widespread adoption.

A stepped uniaxial bar is subjected to forces. The length and area of cross-sections of the two elements are asked to be written. The stiffness matrix of the given information is to be calculated.

Consider a stepped uniaxial bar subjected to forces as shown in the below diagram. The above bar has two different areas of cross-section and lengths. Hence, the bar can be divided into two elements with different areas and lengths.

Let us consider Element 1:

Here, \(l_1\) = Length of element 1

\(A_1\) = Area of cross-section of element 1

Let \(P_1\) and \(P_2\) be the forces applied on Element 1 and Element 2 respectively.

In general, the element stiffness matrix can be written as \(k = AE / Le\), where A is the area of the cross-section, E is the modulus of elasticity, and Le is the length of the element.

Let us calculate the stiffness matrix for Element 1. The stiffness matrix of Element 1, \(k_1\) is given by: 

\(k_1 = (A_1E_1 / l_1) * [1, -1; -1, 1]\)

Let us consider Element 2:

Here, \(l_2\) = Length of element 2

\(A_2\) = Area of cross-section of element 2

The stiffness matrix of Element 2, \(k_2\) is given by:

\(k_2 = (A_2E_2 / l_2) * [1, -1; -1, 1]\)

Now, we need to find the stiffness matrix of the complete bar. Let us consider k as the stiffness matrix of the complete bar. Then, \(k = [k_1 + k_2]\) is the stiffness matrix of the complete bar.

The complete stiffness matrix of the given problem is given by: \(k = [A_1E_1/l_1 + A_2E_2/l_2] * [1, -1; -1, 1]\)

Hence, the stiffness matrix of the given problem is given by \([A_1E_1/l_1 + A_2E_2/l_2] * [1, -1; -1, 1].\)

Answer:

a) ZT = [ 38.786 ∠-4.28° ] ohms

b) ZT = [ 8.673 ∠4.06° ] ohms

Explanation:

Given that;

Voltage V = 480V

three loads of 1) 10Kw, 8 kVAR

2) 5 kVA, 0.9 power factor lagging

3) 12kW, 0.95 pf leading

Now for load1

Active power P = V^2 / R

Resistance R1 = V^2 / P

= (480 * 480) / 10*1000 = 23.04 OHMS

Reactive power Q = 8kVAR

let x be reactance

Q = V^2 / x

8 * 1000 = (480 * 480) / x

x1 = j28.8 ohms (inductive)

Load 2

Active power = kVA * nf = 5 * 9 = 4.5 Kw

Reactive power = sqrt(S^2 - P^2)

= Sqrt (5^2 - 4.5^2)

= 2.179 kVAR

now Resistance R2 = V^2 / P2 = (480 * 480) / 4.5*10^3

= 51.2 ohms

Reactance X2 = V^2 / Q2 = (480 * 480) / 2.178*10^3

X2 = 105.75 ohms

x2 = -j105.75 ohms (capacitive)

Load 3

Active power = 12kW AND PF = 0.95

so

kVA rating = 12/0.95 = 12.63 kVA

reactive power Q3 = sqrt (12.63^2 - 12^2 )

= 3.94 kVAR

Resistance R3 = V^2/P3 = (480*480) / 12*10^3

= 19.2 ohms

Reactance x3 = V2 / Q3 = (480 * 480) / 3.94*10^3

x3 = 58.47 ohms

x3 = -j58.47 ohms (capacitive)

NOW

a)

series combination of R and X

1/ZT = [1/(R1 + jx1)] + [1/(R2-jx2)] + [1/(R3-jx3)]

we substitute

1/ZT = [1/(23.04 + j28.8)] + [1/(51.2 - j105.74)] + [1/(19.2-58.48)]

1/ZT = 0.02571 + j1.92688*10^-3

ZT = 38.67 -j2.897 (total impedance)

so ZT = [ 38.786 ∠-4.28° ] ohms

b)

parallel combination of R AND X

1/ZT = 1/R1 + 1/jx1 + 1/R2 + 1/(-jx2) + 1/R3 + 1/(-jX3)

1/ZT = 1/23.04 + 1/j28.8 + 1/51.2 + 1/(-j105.74) + 1/19.2 + 1/(-58.48)

1/ZT = 0.1150 - j0.008164

ZT = 8.65 +j0.6141

so ZT = [ 8.673 ∠4.06° ] ohms
