In this idealized model, m=1 slug, k=9lb/ft, and the viscous damping factor is 0.15. How do I find the range of frequency ratios for which the magnification will be greater than 1?
How do I find the forced response for A=1, and forcing frequency of 4rad/sec?

Mechnical Vibration Analysis

I have a mass-spring-damper system that is tested to determine the value of the viscous damping coefficient c. Assume k=10lb/ft and m=2 slug. The vibrational amplitude is observed to decrease to 33% of its initial value after two consecutive cycles.
How do I deduce the value of the logarithmic decrement?
