long The hollow thin-walled hollow section of aluminium alloy illustrated below is 1200 mm It has one free end and the other is built into a solid wall. At the free end, the following loads are applied in the directions illustrated and distributed evenly over the perimeter of the section: A central, axial compressive load, P = 10 kN; and A torque, T 0.2 kN.m Properties of the aluminium alloy are given as E 72 GPa and v= 0.32 Calculate the shear stress on the section at the location of the surface element shown due to the torque T; surface element T 1200 109 110 75 80
