2. A composite shaft is made of slipping a bronze tube of 3-in. outer diameter and 2-in. inner diameter over a solid steel
shaft of the same length and 2-in. diameter. The two components are fastened rigidly together at their ends. What is
the largest torque that can be carried by the composite shaft if the working shear stresses are 10 ksi for bronze and
14 ksi for the steel? If the hollow tube is made out of steel and the solid shaft is made out of bronze, what is the
largest torque that can be carried by the composite shaft if the same working shear stresses are applied? For bronze,
G = 6 x 10° psi, and for steel, G = 12 x 10°.
Design a hollow circular steel shaft to transmit an applied torque of 360,000 in-lbs. Theallowable shear stress is 6,000 psi and the inside diameter is to be 0.6 times the outsidediameter.
Select the size of a hollow steel shaft necessary to transmit 150 hp at 250 rpm without
exceeding an allowable shear stress of 7.4 ksi, or having a relative angle of twist beyond an
allowable value of 0.35 degrees per 1-ft length. The ratio k-d,/d,=0.75
