1. Two solid shafts of different materials are rigidly fastened together and attached to rigid supports as shown. The aluminum segment is 3 inches in diameter and G = 4 x '10 " 6 psi. The steel segment has a diameter of 2 inches and G = 12 x 10 " :3 psi. The torque. T = 10 kips.in. is applied at the junction of the two segments. Compute the maximum shearing stress developed in the assembly. pwiber_image_2022v05-19_23-19-Do-9?E.jpg 2. A load P is supported by two concentric steel springs. The inner spring consists of 30 turns of 20 mm diameterwire on a mean diameter of 150 mm; The outer spring has 2D turns of SUI-mm diameter wire on a mean diameter of 200 mm. Compute the maximum load that will not exceed a shearing stress of 14C! Mpa in either spring. Use (3 = 83 Gpa. 3. Compute the shearing stress if a torque T = 200 Nm is applied to a thin-walled tube having a cross section in the shape of a regular hexagon with constant wall thickness 2 mm and side length of 1011) mm
