A 1.0 inch diameter steel shaft has an ultimate tensile strength of S₁ = 110 ksi and a machined surface. Determine the life of the shaft "N" (in % of cycles) if it is subjected to fully reversed torsional loading caused by a fully reversed torque of 683 ftlb. The application for this particular shaft requires 95% reliability. Ans. 2.14 x 104 cycles
