Figure 1 shows the shaft of a disc sander, made of steel, which has a tension of failure ou-900 MPa and a yield stress oyp=750 MPa. The axis goes from having a diameter of 16 mm to another of 18 mm through an agreement radius of 5 mm. The limit of shaft fatigue is 290 MPa. The most severe loading occurs when an object (which is considered punctual) near the periphery of the disc (100 mm from the center of the axis), with force enough to develop a frictional torque of 12 Nm on the shaft. The coefficient Friction between the object and the disk is 0.6. For these conditions described, it is requested calculate the safety coefficient of the shaft at infinite life. objeto 100mm objeto 5mm 50mm empotramiento WWW.
