Question

The composite shaft shown in the figure is manufactured
by shrink-fitting a steel sleeve over a brass core
so that the two parts act as a single solid bar in torsion.
The outer diameters of the two parts are d1 = 40 mm
for the brass core and d2 = 50 mm for the steel sleeve.
The shear moduli of elasticity are Gb = 36 GPa for the
brass and Gs = 80 GPa for the steel.
(a) Assuming that the allowable shear stresses
in the brass and steel are τb = 48 MPa and
τs = 80 MPa, respectively, determine the maximum
permissible torque Tmax that may be
applied to the shaft.
(b) If the applied torque T = 2500 kN . m, find
the required diameter d2 so that allowable shear
stress τs is reached in the steel.
