Q1: An open loop system has a forward path transfer function (42.25)/s(s + 6.5). The unit step response of the system starting from rest will have its maximum value at a time equal toA
0 sec
B
0.56 sec
C
5.6 sec
D infinity
ANS:D - infinity
Unit step response is Taking inverse transform, the time domain response is - 1 + 6.5t + e-6-5t. It reaches maximum value at t = infinity.
