Assume that Young's Modulus for bone is 1.50x10^10 N/m^2 and that the bone will fracture if more than 1.50x10^8 N/m^2 is exerted. (a) What is the maximum force that can be exerted on the femur bone in the leg if it has a minimum effective diameter of 2.60 cm? (b) If a force of this magnitude is applied compressively, by how much does the 22.0 cm long bone shorten? Y=F/A is what I tried for Part A but im not sure if I', using the right area. Without the first part I can't even attempt B.
