A simply supported rotating shaft with a diameter d = 2 cm is loaded as shown with F = 1600 N and F2 = 750 N. Consider the bearings at A and B to be frictionless with bearing A carrying the axial thrust. The loads are acting at a point where a = b = 20 cm. The material of the shaft has an ultimate strength Su = 680 MPa and actual endurance strength Sn' of 325 MPa. Assume there are no stress concentration. A F Fill in the boxes with the correct answer with 2 decimal places even if whole number (ex. 2.00). The maximum bending moment is B The alternating normal stress is The internal axial load at a section 10 cm to the left of B is The mean normal stress is The factor of safety based on endurance stength is N-m.
