1. The problem statement, all variables and given/known data Assume that Young's Modulus for bone is 1.50 X 10^10 N/m2 and that the bone will fracture if more than 1.50 X 10^8 N/m2 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 24.0 cm long bone shorten? 2. Relevant equations Y = tensile stress / tensile strain tensile stress = F/A tensile strain = delta L / Initial L 3. The attempt at a solution I understand the concept, but i cant figure out where to plug the numbers into. Since I dont have any lengths for part a, I guess you wouldnt use the entire young's equation, but what exactly would I use? Any help would be great! Thanks!
