The free vibration response of a SDOF spring-mass-damper system is shown below
tude of vibration decreases by 25% every five cycles of motion. Determine the
atio and damping coefficient of the system if k = 20 lb/in and m 10 lb.
ust because the amplitude decreases 25% every five cycles does NOT mean that it
5% every cycle.
