Homework Statement
A suspension wire is given and the problem is to find out it's rigidity modulus. Say the wire is of length 'l' and a mass 'm' is suspended with the help of the wire.
Homework Equations
All i know is Young's modulus or 'Y' is Y=stress\strain
The Attempt at a Solution
My first doubt is:- is Young's modulus the same as rigidity modulus. And the second problem i can find out the tension in the wire as well as it's length. But which length is to be taken? The changed length? Or the initial length? With a screw gauge i may be able to determine the radius of the wire and consequently the cross sectional area. I just need some step by step procedures and theory on how to find out this thing.
