Question

1)A 4.50E+3-kg block is lifted at a constant speed of 5.60 cm/s by a steel cable that passes over a massless pulley to a motor driven winch. The radius of the winch drum is 35.0 cm. What is the torque exerted on the drum by the cable?

2)Using your answer from above and the angular velocity of the drum, determine the power delivered to the drum by the winch motor. There is an other way to calculate the power of the winch using the rate of rise of the block, try to the find it and check your answer.

Explanation / Answer

the torgue would be t=F.r F=mg 15435Nm w=v/r w=0.16 T.w=15435*0.16=2469.6W This is also equal to MG.V=2469.6W
