Homework Statement
Consider the spring-mass system shown. A dynamic load, P(t), is applied with a frequency of 300 rpm. The helical compression spring is made of a music wire. When installed, the spring force is to vary between 100 and 500 N while the spring height varies over a range of 10 mm. The object attached to its end has a mass of 1.7 kg.
Derive an expression for natural frequency.
Homework Equations
None. There might be some unnecessary information in the question, I'm not sure. This is an example from my machine design course.
The Attempt at a Solution
I know that a spring's natural frequency is 1/2∏ √(k/m). But I don't know this applies to this question.
Thanks!
