The torsional assembly of Figure P6.75a consists of a solid 75-mm-diameter bronze [G = 45 GPa] segment (1) securely connected at flange B to solid 75-mm-diameter stainless steel [G = 86 GPa] segments (2) and (3). The flange at B is secured by four 14-mm-diameter bolts, which are each located on a 120-mm-diameter bolt circle (Figure P6.75b). The allowable shear stress of the bolts is 90 MPa, and friction effects in the flange can be neglected for this analysis. Determine
(a) the allowable torque TC that can be applied to the assembly at C without exceeding the capacity of the bolted flange connection.
(b) the maximum shear stress magnitude in bronze segment (1).
(c) the maximum shear stress magnitude in stainless steel segments (2) and (3).
