Mechanical Engineering : Process Instrumentation And Control QUESTIONS AND ANSWERS :: part5 : 1 to 5

Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

1.The immediately apparent feature of an observed transient performance is :

the existence and magnitude of the maximum overshoot
the frequency of the transient oscilla-tion
the response time
all of the above
none of the above.

2.The transient performance, i.e. the behaviour of the output variable as the system changes, from one steady-state condition to another, is evaluated in terms of;

accuracy
settling time
response time
peak time
maximum overshoot, rise time, and response time.

3.When an automatic control system is the output variable overshoots its desired steady-state condition and a transient oscillation occurs :

underdamped
over damped
critically damped
damped
without damping.

4.The steady state output of the system to input sinusoids of varying frequency is referred to as :

frequency response of a system
Nyquist plot
Bode plot
transient response
logarithmic plot.

5.The overshoot and the settling time are maximum with :

underdamped system
overdamped system
critically damped system
damped system
non damped system.
