Assume that Young's Modulus for bone is 1.50 ✕ 10¹⁰ N/m² and that the bone will fracture if more than 1.50 ✕ 10⁸ 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 2.70 cm?

(b) If a force of this magnitude is applied compressively, by how much does the 28.0 cm long bone shorten?

Answer 1

Answer #1

Remember the stress is giving by: a) Е A In this case 1.50 x 108 т? Emаx = πα? А 4 Then: Emax nd(1.50 x 108)7(0.027)2 = 85883
