Question

A vertebra is subjected to shearing force of 465 N. Find the shear deformation, taking the vertebra to be a cylinder 3.00cm high and 3.00cm in diameter. The shear modulus for vertebrae is 8.00 *10^10 N/m^2

Answer 1

Shear stress is defined as the Force acting on an Area.

You are given F = 465 N

For a cylinder, surface area is given by: 2*pi*r*h + 2*pi*r^2
radius r in this case is 3/2 cm
height h in this case is 3 cm

Try finding the shear stress now: S = F/A

Answer 2

2.47*10^-7 m came out to be the correct answer. it needed converted to m, i left that part out of the question.
