Ok here is what I have so far on this problem I know that I'm suppose to find the Cross sectional area (A) in this problem. But I'm not sure how I would go about doing that with the 2 radius. Do I find the area of each and add them together? Or perhaps subtracting them?

I know that I'm suppose to use the formula F = Y (Delta L/ L0) (A) . Y = Youngs Modulus, Delta L = Change in Length/ L0 is initial Length, A = crossectional area.

The force applied here would be (58 kg)(9.8 m/s) right? The F value

young's Modulus is given as well as the initial length.

I know that to find the strain it is the ratio between Delta L and L0 right? And to find the change in how much it is compressed by solving for the Delta L.

So my main difficulty is the

**cross sectional area**of this problem and perhaps not working right to find the total force?
