In Figure 2 below, the belt puley diameter at B is 65 mm and weighs 10 kg. The belt pulley diameter at D is 86 mm and weighs 12 kg 03m 04m 2 KN 0.3 m 65 mm 1 KN 3 KN B6 mm 3kN Figure 2 Transmission drive shaft (dimensions in mm) 3.1 Calculate the resultant bending moments at B and C The material selected for the shaft is hot-rolled (HR) AISI/SAE 1050 with ultimate strength of 620 MPa and yield strength of 340 MPa Operating temperatures are not expected to exceed 60 C and the operating environment in non-corrosive. The shaft is to be designed for non-limited life of greater than 10 cycles with a 9096 survival rate The shaft will carry a steady driving torque of 2000 Nm and rotate at 69 rpm A sled runner key-way will be used for the overhung pulley and a profile keyway for the mid-mounted pulley Assume the shaft is of constant diameter for the calculation You may also assume that the safety factor is 1 76. 3.2 Using the ASME equation delermine the diameter ai of the dve shaft which has the loading parameters illustrated in Figure 2 Assume he aamerer De acout 60mm
