A springmassdamper system with negligible mass can be approx

A spring-mass-damper system (with negligible mass) can be approximated as a first order system. The system has a spring constant of k = -1 N/m and a damping coefficient of c = 2 Ns/m. The system is subjected to a harmonic force with amplitude = 0.5 N. What is the forcing frequency report cyclic frequency in Hz and maximum measured displacement if the displacement lags the forcing by 45 degrees?

Solution

The answer of following question is as follows.

The frequency of the given spring mass is 78 hertz .

The displacement of the given spring mass is 8mm
