Identify three engineering companies which operate respectively in each of the three sectors (Primary, secondary and tertiary). You could consider companies which send apprentices to the college where you are studying or you could find companies from the internet or other information sources


b) Describe the engineering functions carried out by each company in their particular sector     (P1) 


The manager of company has asked his assistant to present him with the list the ages of all the workers working in manufacturing division who are having the experience of 20 years. The assistant of thee manager replied him with the list of 10 employees who are having the experience of 20 years. Write a program that store the age of all 15 employees in 1D array and then print the total count of employees whose age lies between 50 and 60. Use functions to solve this task

Input Format ->57 49 54 48 59 55 46 57 58 60 58 62 56 70 73

Constraints ->The Age of the employees should be greater than or equal to 40 and less than or equal to 60. If constraints do not match then show "wrong input" Output Format

A 1hp, DC shunt motor is loaded by a constant torque of 20Nm. The armature resistance

of the motor is 4Ω, and the field constant K=2.5Vsec. the motor is driven by a full-wave

SCR converter. The power source is 200V, 60Hz. The triggering angle of the converter is

60 and the conduction period is 150. Calculate the motor speed and the developed

power.


A 150V, DC shunt motor drives a constant-torque load at a speed of 1500rpm. The

armature and field resistances are 2Ω and 150Ω, respectively. The motor draws a line

current of 10A at the given load.

(a) Calculate the resistance that should be added to the armature circuit to reduce the

speed by 50%.

(b) Assume the rotational losses to be 100W. calculate the efficiency of the motor without

and with the added resistance.

(c) Calculate the resistance that must be added to the armature circuit to operate the

motor at the holding condition


A 150V, DC shunt motor drives a constant-torque load at a speed of 1500rpm. The

armature and field resistances are 2Ω and 150Ω, respectively. The motor draws a line

current of 10A. Assume that a resistance is added in the field circuit to reduce the field

current by 25%. Calculate the armature current, motor speed, value of the added

resistance and extra field losses.


A 200V DC shunt motor drives a constant-torque load at a speed of 1800rpm. The

armature & field resistance is 2Ω and 120Ω respectively. The motor draws a line current

of 10A. Assume that a resistance is added in the field circuit to reduce the field current by

20%. Calculate armature current, motor speed and value of the added resistance and

extra field losses.


A 500V, DC shunt motor has armature and field resistance of 2.5Ω and 500Ω respectively.

When the motor run unloaded, the line current is 3A and the speed is 1200rpm. Calculate

torque Developed at full load armature current of 50A, the motor speed if the load is

constant-torque type when 3Ω resistance is added to the armature circuit and the motor

speed if the field is reduced by 15%.


Weim (R = 0.4968 Btu/lbmoR) is compressed isothermally from 14.7 psia 68°F. The compression ratio is 4. Calculate the work done by the gas.


A compact disc (CD) records audio signals digitally by PCM. Assume audio signal's bandwidth to be 15 kHz. If signals are sampled at a rate 20% above Nyquist rate for practical reasons and the samples are quantized into 65,536 levels, determine bits/sec required to encode the signal and minimum bandwidth required to transmit encoded signal. 


What is the Carson’s rule to define the bandwidth of FM signals? Calculate the modulation index of an FM signal having carrier swing of 80 kHz, when modulating signal has the frequency of 5 KHz.
