Between each pair of vertebrae in the spinal column is a cylindrical disc of cartilage. Typically, this disc has a radius of about 3.0×10−2m and a thickness of about 7.0×10−3m The shear modulus of cartilage is 1.2×107N/m2 Suppose a shearing force of magnitude 11 N is applied parallel to the top surface of the disc while the bottom surface remains fixed in place . How far does the top surface move relative to the bottom surface?
