Q2 A hollow circular cold-rolled stainless steel [G = 12,000 ksi] tube (1) with an outside diameter of 2.15 in. and an inside diameter of 1.80 in. is securely shrink fit to a solid 1.80 in. diameter cold-rolled bronze [G = 6,300 ksi] core (2) as shown in Figure 2. The length of the assembly is L = 18 in. The allowable shear stress of tube (1) is 58 ksi, and the allowable shear stress of core (2) is 22.5 ksi. Determine: (a) the allowable torque T that can be applied to the (1) (2) tube-and-core assembly. (b) the corresponding torques produced in tube (1) and core (2). (c) the angle of twist produced in the assembly by the allowable torque T. T FIGURE 2 BI T
