Torsion 6:

Under normal operating conditions, the electric motor exerts a 12-kip.in. torque at E. Knowing that each shaft is solid, determine the maximum shearing stress in (a)shaft BC,(b)shaft CD,(c)shaft DE.

Torsion 7:

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

Torsion 8:

The allowable shearing stress is 15 ksi in the steel rod AB and 8 ksi in the brass rod BC. Knowing that a torque of magnitude T = 10 kip.in. is applied at A,determine the required diameter of (a) rod AB, (b) rod BC.

Torsion 9:

The solid rod AB has a diameter d_AB = 60 mm. The pipe CD has an outer diameter of 90 mm and a wall thickness of 6 mm. Knowing that both the rod and the pipe are made of steel for which the allowable shearing stress is 75 MPa, determine the largest torque T that can be applied at A.

Torsion 10:

The solid rod AB has a diameter dAB = 60 mm and is made of a steel for which the allowable shearing stress is 85 MPa. The pipe CD, which has an outer diameter of 90 mm and a wall thickness of 6 mm, is made of an aluminum for which the allowable shearing stress is 54 MPa. Determine the largest torque T that can be applied at A.
