The femur is a bone in the leg whose minimum cross-sectional area is about 4.3 x 10-4 m2. A compressional force in excess of 8.0 x 104 N will fracture this bone. Bone has a compressional Young's modulus of 9.4 x 109 N/m2.
(a) Find the maximum stress that this bone can withstand.
(b) What is the strain that exists under a maximum-stress condition?
