4. A tube composed of a wrought aluminum alloy 6061-T6 is designed to transmit a torque in a control mechanism; however the compressive stress in the tube must not exceed 7000 psi to prevent the tube from buckling. The tube has an outside diameter of 1.25 in., a wall thickness of 0.065 in. and total length of 2.0 ft. Find the maximum torque which can be applied and the angle of twist over the length of the tube at the maximum torque.
