a drum with negligible mass, 0.400 m in diameter, is attached to the motor shaft, and the power output of the motor is used to raise a weight hanging from a rope wrapped around the drum. how heavy a weight can the motor lift at constant speed?

The motor can lift an object of weight equal to 179 kg.  On the hanging weight since it is the constant speed we can assume that object is in equilibrium and Tension = m*gWhere m = mass and g = acceleration due to gravityOn the drum since it is also moving with constant angular speed net torque on it will be zero.τ - TR =0  Where τ = torque, T= tension and R= Radius of drum = 0.2 mReplacing the expression for Tension of the rope in above equation:τ = mgRSolving for m using R = 0.2m, g = 10 m/ s2 and τ = 358 N.mm =  [tex]\frac{358}{0.2 X 10}[/tex] = 179 kgTo learn more about torque click herehttps://brainly.com/question/6855614#SPJ4
