Question

A flat belt, 8 mm thick and 100 mm wide transmits power between two pulleys, running at 1600 m/min. The mass of the belt is 0.9 kg/m length. The angle of lap in the smaller pulley is 165° and the coefficient of friction between the belt and pulleys is 0.3. If the maximum permissible stress in the belt is 2 MN/m2, find (i) Maximum power transmitted, and (ii) Initial tension in the belt. [Ans. 14.821 kW; 1.322 kN]

Step 1

The velocity \( v \) of the belt can be calculated using the formula: \[ v = \frac{{\text{Linear speed (m/min)}}}{60} \] Given the linear speed is 1600 m/min, the velocity \( v \) is: \[ v = \frac{1600}{60} = 26.67 \text{ m/s} \] Show more…
