1. The problem statement, all variables and given/known data a. compute the torque developed by an industrial motor whose output is 225kW at an angular speed of 4000rpm. b. a drum with negligible mass and .4m 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 life at constant speed? c. at what constant speed will the weight rise? 2. Relevant equations rpm x 2pi/60s = rad/s angular speed (w) = 418 rad/s 1Kw = 3.6x10^6J Power = (torque)(angular speed)? V = Rw 3. The attempt at a solution i changed the w from rpm to rad/s I converted kW to J and got 81x10^8J I'm not sure that's right, that seems really big to me. and if Power = (torque)(angular velocity) then i rearranged and solved for torque and got 19.4x10^6, which seems high to me I have no idea what to do with part B I know that tension in the rope equals the weight of the object tied to it.
