The Pinion has 18 teeth. The pinion is manufactured from heavy-duty 817M40 steel. Select a suitable gear, specifying the module and the face width based on the Lewis formula. Full Marks: 40, Good Luck OUNISA 2023 wQuestion 1 [30 Marks] In Figure 1.1 below, the belt pulley diameter at B is 65 mm and weighs 10 kg. The belt pulley diameter at D is 86 mm and weighs 12 kg. Figure 1.1: Transmission drive shaft (dimensions in mm) 1.1 Calculate the resultant bending moments at B and C. The material selected for the shaft is hot rolled (HR) AlSl/SAE 1050 with an ultimate strength of 620 MPa and yield strength of 340 MPa. Operating temperatures are not expected to exceed 60C and the operating environment is non-corrosive. The shaft is to be designed for non-limited life of greater than 103 cycles with a 90% survival rate. The shaft will carry a steady driving torque of 2000 Nm and rotate at 69 rpm. A sled runner keyway 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. MAJOR TEST 3 MEE231V 2023 1.2 Using the ASME equation, determine the diameter (d) of the drive shaft, which has the loading parameters illustrated in Figure 1.1. Assume the diameter will be about 60 mm
