Question: a 15 kw 2500 rpm electric motor drives a machine...

Question details

A 1.5 kW, 2,500 rpm electric motor drives a machine through a flat belt. The driven shaft speed is 1,000 rpm. The centre distance, c 625 mm, radius r1-37.5 mm friction f0.35 and belt weight, w 1.75 N/m. Given the pitch line velocity of the belt is 9.8 m/s, the angle of wrap on the small pulley is 170° and the torque at A is 5.73 Nm What are the tension forces F and F2? (10 marks)
