PROBLEM 01: Hollow bar length is 1.40m long and tube length is three-fourth as long as the bar. Torque T=1100N.m acts at the free end of the bar. Both the bar and tube are made of an aluminum alloy with shear modulus of elasticity G=27GN/m². Given that d1=35mm, d2=45mm, d3=60mm, d4=70mm. Determine the following: a. Maximum shear stress in both the bar and tube b. Angle of twist at the end A of the bar. (In degrees) Tube Fixed plate End plate Tube d3 d1 d2 d4 Bar Cross-section of the bar and tube

1. The assembly has the diameters and material makeup indicated. If it fits securely between its fixed supports when the temperature is T; = 70°F, determine the average normal stress in each material when the temperature reaches T2 = 130°F. 304 Stainless steel - 2014-T6 Aluminum -C 86100 Bronze A 12 in. 8 in.
