I am trying to design a spring given the following measurements:(adsbygoogle = window.adsbygoogle || []).push({});

Spring Stiffness is 400N/m or 295 ft lbs

Outer Diameter of spring is 0.25 in

Free Length is 3 cm or 1.18 in

Load is max: 5lbs

I am having trouble with:

Calculating the Spring Diamter so as the spring is not over damped or under damped

Ensuring the spring won't buckle

Determining the number of coils necessary knowing the spring stiffness

Any help would be great! Thanks!
