A solid steel shaft of radius b is pressed into a steel disk of outer radius 2b and the length of hub engagement t = 3b (Figure 8.11). Calculate the value of the radial interference in terms of b. Given: The shearing stress in the shaft caused by the torque that the joint is to carry equals 120 MPa; E = 200 GPa, and f = 0.2.
