1. The problem statement, all variables and given/known data
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. 2. Relevant equations elastic limit=stress =F/A 1.6 x 10^8=100/ (pie)d^2 I can't get the answer.please help 3. The attempt at a solution

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.
