The femur is a bone in the leg whose minimum cross-sectional area is about 4.0E-4 m^2. A compressional force in the excess of 6.8E4 N will fracture this bone.
A) Find the maximum stress that this bone can withstand
B) What is the strain that exists under a maximum-stress condition

A) Find the maximum stress that this bone can withstand

B) What is the strain that exists under a maximum-stress condition

I already solved part A to be 1.7E8 N/m^2, but I cant figure out part B. Any help would be greatly appreciated, thx
