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?
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.

Correct : a
