(II) If a compressive force of 3.3x104 N is exerted on the end of a 22-cm-long bone of cross-sectional area 3.6 cm2 (a) will the bone break, and (b) if not, by how much does it shorten?
Assume Young’s modulus for bone is 1.40×1010 N/m2
. The bone breaks if stress greater
than 1.50 × 109 N/m2
is imposed on it.
(i) What is the maximum force that can be exerted on the femur bone in the leg if it
has a minimum effective diameter of 2.50 cm?
(ii) If this much force is applied compressively, by how much does the 20.0 cm long bone
shorten?
(II) An iron bolt is used to connect two iron plates together. The bolt must withstand shear forces up to about 3300 N. Calculate the minimum diameter for the bolt, based on a safety factor of 7.0.
