Consider an open loop 1-degree-of-freedom mass-spring damper system. the system has mass 4.2 kg, and spring stiffness of 85.9 n/m, and damping coefficient of 1.3 n. s/m. what is the non-dimensional damping ratio of the system? use at least 4 significant digits after the decimal point.

Damping ratio  

Explanation:

Given that

m=4.2 kg,K=85.9 N/m,C=1.3 N.s/m

We need to find damping ratio

We know that critical damping co-efficient

  N.s/m

Damping ratio() is the ratio of damping co-efficient to the critical damping co-efficient

So

So damping ratio
