A solid steel shaft of radius b is to be pressed into a wrought iron hub of outer radius c and length L. L is also the length of engagement of the shaft and hub. Calculate (a) the interface pressure in MPa; (b) the force needed for the press fit in kN; and (c) the torque capacity of the assembly in kN-m. Let b = 50mm, c = 100 mm, L= 180 mm, Es = 210 GPa, Eiron = 190 GPa, f = 0.15. Assume that the maximum allowable tangential stress in the assembly is 25 MPa.
