Power is transmitted by an electric motor to a machine by using a belt drive. The tensions on the tight and slack side of the belt are 2200 N and 1000 N respectively and diameter of the pulley is 600 mm. If speed of the motor is 1500 r.p.m, find the power transmitted.

Power is transmitted by an electric motor to a machine by using a belt drive. The tensions on the tight and slack side of the belt are 2200 N and 1000 N respectively and diameter of the pulley is 600 mm. If speed of the motor is 1500 r.p.m, find the power transmitted. Correct Answer 56.548 kW

Power = Tω = Frω = Fv F = T1 – T2 = 2200 – 1000 = 1200N v = пDN/60 = п x 600 x 1500/1000 x 60 = 47.12 m/s P = 1200 x 47.12/1000 = 56.548 kW.
