(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.
(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?
