Question 1: [15 marks] Cm 10 mm. The Figure is a schematic drawing of a counter shaft with two belt pulleys at B & C and two supporting bearings at A and D. Loads acting at the belt sides of pulleys are indicated. If the power transmitted from the pulleys B and C is 5 and 8 (kW) respectively and the motor speed is 1000 rpm. You are required to: 1- Determine the values of the belt forces F. F, F, and F.). 2- Draw the bending moment diagram and torque diagrams. 3- Calculate the shaft diameter. if its material is St 42 (Gul-420 MPa) and factor of safety + 2) [5 Marks] 36,417 W=2 TTn F3 325 cm A Datto 20 F2 Pulley (C) F4 Pulley (B) 325 cm F = 2 F F [5 Marks] [5 Marks] F = 2 F4 B 40 cm 20 (o=0.66) & T-0.56 Motor
