Machine Elements

The armature shaft of a 50 kW, 580 rpm electric motor, mounted on two bearings A and B, is shown in Fig. The total magnetic pull on the armature is 5 kN and it can be assumed to be uniformly distributed over a length of 400 mm midway between the bearings. The shaft is made of steel with an ultimate tensile strength of 770 N/mm? and yield strength of 580 N/mm?. Determine the shaft diameter using the ASME code if, k = 1.5 and k, = 1.0 Assume that the pulley is keyed to the shaft. 150 400 10 N/mm 150 300 1000 N 3000 N
