Calculate Joules from Peak Energy and Displacement

Postby RAM » Fri Sep 23, 2005 4:16 am

I am trying to determine Joules from a calculation of 4172 N of force and 13.33mm displacement. I have determined this to be 55.6J, i.e 4172 * 0.0133m.

Is this correct?

It would be correct if the force is uniform over the entire displacement.

If it is not, you need to integrate the force as a function of displacement, and it would be the integral of f(x)dx. If you have any data on variation of force, you could plot it vs displacement and estimate area under the curve.
