Statically Indeterminate Torque-Loaded Members

• Same method of analysis as for axial loaded members

• Sum of the moments

• Compatibility equation– Angle of Twist

The following shaft is made from a steel tube with a 2 inch outside diameter which is bonded to a brass core with a 1 inch diameter. Determine the maximum shear stress in each section if a torque of 250 lb-ft is applied at the end of the shaft.G for steel is 11400 psi and G for Brass is 5200 psi.
