## Homework Statement

The elastic limit for a type of material is 1.6 x 10^8 Pa.Determine the minimum diameter if a wire which is made of this material so that it can support a load of 100N without the stress exceeding the elastic limit.

## Homework Equations

elastic limit=stress
=F/A
1.6 x 10^8=100/ (pie)d^2

In your S = F/A formula, replace A with the area of the circular wire.
Solve for the radius or diameter.
Put in the numbers for S and F.
