(1) A mass of 3.0 kg is suspended from a vertical spring and produces a static deflection of 60 mm.(adsbygoogle = window.adsbygoogle || []).push({});

The system is also subjected to viscous damping of 36 N s/m.

Calculate the value of the:

(a) natural frequency

i. In Hz

ii. And rad/s

(b) damping ratio

(c) and what will be the steady state amplitude of the oscillations produced when the mass is acted on by a periodic force of amplitude 10 N and frequency 1.5 Hz?

I really don't know how to answer this question, and would appreciate any help if possible.

Many thanks in advance.
