A thick-walled tube has an inner radius ri = 10 mm and an outer radius r0 = 15 mm. It is made from polycarbonate, PC. What is the maximum torque Tf that the tube can carry without the onset of yield? Retrieve the (mean) yield strength of PC from Appendix A3, the expression for the torque at onset of yield from Appendix B6 and that for the polar moment of a thick-walled tube from Appendix B2 to find out.
