An open belt drive connects two pulleys 1.2 m and 0.5 m diameter on parallel shafts 3.6 m apart. The belt has a mass of 1kg/m length and the maximum tension in it is not to exceed 2kN. The 1.2 m pulley, which is the driver, runs at 200 rpm. Due to the belt slip on one of the pulleys, the velocity of the driven shaft is only 450 rpm. If the coefficient of friction between the belt and pulley is 0.3, find: 1. Torque on each of the two shafts, 2. Power transmitted, 3. power lost in friction, and 4. efficiency of the drive.

An open belt connects two flat pulleys. The pulley diameters are 300 mm and 450 mm and the corresponding angles of lap are 160° and 210°. The smaller pulley runs at 200 r.p.m. The coefficient of friction between the belt and pulley is 0.25. It is found that the belt is on the point of slipping when 3 kW is transmitted. To increase the power transmitted two alternatives are suggested, namely (i) increasing the initial tension by 10%, and (ii) increasing the coefficient of friction by 10% by the application of a suitable dressing to the belt. Which of these two methods would be more effective? Find the percentage increase in power possible in each case.
