A shaft is to be manufactured from a steel having an ultimate tensile strength of 420 MPa, and a yield stress of 305 MPa. The shaft has a solid circular cross section of diameter 50 mm and is subjected to a sinusoidally varying torque ranging from 60 Nm to 130 Nm. It has also been established that the shaft has a fully-corrected endurance limit of 129 MPa and that a torsional fatigue stress concentration factor, kf = 2.1, exists at...

Problem #1 A cylindrical rod of copper (E 110 GPa) having a yield strength of 240 MPa is to be subjected to a load of 6660 N. If the length of the rod is 380 mm, what must the diameter be to allow an elongation of 0.50 mm? A cylindrical specimen of some alloy 8 mm in diameter is stressed elastically in tension. A force of 15,700 N produces a reduction in the specimen diameter of 5 10-3 mm. Compute...
