The aluminum rod AB (G = 27 GPa) is bonded to the brass rod BD (G= 39 GPa). Knowing that portion CD of the brass rod is hollow and has an inner diameter of 40 mm, determine the angle of twist at A. 60 mm TB 1600 N-m 36 mm ΤΑ = 800 N.m A 400 mm q 375 mm 250 mm Then, determine the maximum and minimum shearing stress in shaft CD.

The allowable shearing stress is 15 ksi in the 1.5-in.-diameter steel rod ABand 8 ksi in the 1.8-in.-diameter rod BC. Neglecting the effect of stress concentrations, determine the largest torque that can be applied at A

Under normal operating conditions, the electric motor exerts a torque of 2.4 kN·m on shaft AB. Each shaft is solid with diameter d 52 mm. In order to reduce the total mass of the assembly, a new design is being considered in which the diameter of shaft BC will be smaller. Determine the smallest diameter of shaft BC for which the maximum value of the shearing stress in the assembly will not be increased.        The smallest diameter of shaft BC is  mm.

The aluminum rod BC (G= 26 GPa) is bonded to the brass rod AB (G= 37 GPa). Each rod is solid and has a diameter of 13 mm. If TC = 30 N-m and Tg 55 N-m, determine the angle of twist at C. 200 mm 300 mm Brass TB Aluminum Te
