A single V-belt drive system is powered by an electric motor with a speed of 2691 rpm and transmits a power 11 kW. The driving pulley is connected to the driven pulley by a single V-belt of angle 18 degrees and a unit weight of 2.18 N/m. The angle of wraps between the belt and pulley is approximately 175 degrees. The driven shaft is attached to a cylindrical pulley of 101 mm and runs at a speed of 1221 rpm.
Acceleration due to gravity g is exactly 9.81 m/s2.
If the initial belt tension is marginally adequate to prevent slippage and the coefficient of friction f is limited to 0.20, determine the maximum tension P1 that the belt can handle. Use 2 decimals; a variation of 5% is allowed for.

Q2. Figure Q2 shows a shaft which transmits a power of 48 kW through flat belts. Pulley A is driven by a motor which rotates at 3000 rpm. The diameter of pulley A is 400 mm and that of pulley B is 250 mm. The thickness of the belts is 4 mm and they are made of a material with density of 1100 kg/m3. Assume no sliding between pulleys and belts a) Calculate the speed of the belt and the...
Q1 A belt drive and pulley arrangement is designed to transmit 75 kW of power at 1200 rpm, generated by a six-pole squirrel-cage induction motor. The belt connects two shafts 3 m apart, with axes in the same horizontal plane. The driven shaft runs at half the angular speed of the driver and it runs a light shock machinery. As a design engineer you need to do the following; i. Design shafts suitable for this application (20 marks) ii. Select...
