An open belt drive connects two pulleys 1.2 and 0.5m diameter on parallel shafts 3.6m apart. The belt has a mass of 0.9kg/m length and maximum tension in it is not to exeed 2kn. The 1.2m pulley which is the driver runs at 200rev/min. Due to belt slip on one of the pulleys the velocity of the driven shaft is only 450rev/min. Calculate the torque on each of the two shafts,the power transmitted and the power lost in friction. U=0.3 what is the efficiency of the drive.
