Question Statement:
Which of the following statement(s) is/are true about harmonically excited forced
vibration of a single degree-of-freedom linear spring-mass-damper system?
Options:
- (A) The total response of the mass is a combination of free vibration transient and steady-state response.
- (B) The free vibration transient dies out with time for each of the three possible conditions of damping (under-damped, critically damped, and over-damped).
- (C) The steady-state periodic response is dependent on the initial conditions at the time of application of external forcing.
- (D) The rate of decay of free vibration transient response depends on the mass, spring stiffness and damping constant.
