Q. The femur is a bone in the leg whose minimum cross-sectional area is about 4.5 x 10-4 m2. A compression force in excess of 7.7 x 104 N will fracture this bone. Bone has a compression Young's modulus of 9.4 x 10^9 N/m2. (a) Find out the utmost stress that this bone can withstand. (b) What is the strain that exists under a maximum-stress condition?
