A tube is rigidly bonded to wall at A, and has torques applied at positions B and C. The tube length from A to B is 300 mm, and a torque of 3 kNm is applied as shown in the diagram. The length from B to C is defined by LBC, and the torque applied at Cis Tc. The tube has outer and inner diameters of 60 and 50 mm respectively, and is made from an aluminium alloy having a Shear Modulus of 80 GPa. А B с To=3 kNm Tc LAB=300 mm LBC
D Question 1 1 pts If Tc is 4.2 kNm, and Loc is 353 mm, calculate the magnitude of the maximum shear stress occurring in the tube due to torsion. You are to provide your answer in MPa, to 1 decimal place.
Question 2 1 pts If Tc is 4.6 kNm, and Loc is 415 mm, calculate the total angle of twist at position of the tube, relative to A. You are to provide your answer in degrees, to 2 decimal places, paying careful attention to the sign of your answer.
