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?
Y = tensile stress / tensile strain
tensile stress = F/A
tensile strain = delta L / Initial L
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!
