A 1-in-diameter solid round bar is made of AISI 1040 CD steel (sy = 71 kpsi, Su = 85 kpsi). It is operating at a temperature of 300°F, and is subjected to a purely reversing torque of 2000 lbf.in. Estimate the number of cycles to failure if the expected reliability is 99%. Redo the solution for a reversing torque of 8500 lbf.in. Note: The Von Mises stress for pure torsion would be o' = √3T².
