Determine the angle of twist caused by a 25kip – in torque T in the 3in diameter solid aluminium shaft shown (G = 3.7 * 10°psi). Resolve assuming the solid shaft has been replaced by a hollow shaft of the same outer diameter and a 2in inner diameter. ` 4 ft. 3 in. T

2. If the solid shaft is made from a red brass alloy having an allowable shear stress of Tallow = 4 ksi, determine the maximum allowable torque T that can be applied at B. (please note that the problem is statically indeterminate!) 2 ft 4 in. 2 in. T 2 in. 4 ft

The 45-mm-diameter A992 steel shaft is subjected to the torques shown where T=750 N-m. 400 N-m 200 N- m 200 mm T. 600 mm 600 mm A Part A Determine the angle of twist of the end A.
