Motor Lifting a Mass#

A motor with an efficiency of $params.e$ is rotating a $params.r\mathrm{m}$ radius wheel at $\dot{\theta }=params.RPM\mathrm{R}\mathrm{P}\mathrm{M}$ to lift a $params.m1\mathrm{k}\mathrm{g}$ mass.

Part 1#

How much power does the motor consume?

Answer Section#

Please enter in a numeric value in W.

Part 2#

After adding an $params.m2\mathrm{k}\mathrm{g}$ load, you notice the wheel spins slower. The power consumption does not change. What is the new RPM?

Answer Section#

Please enter in a numeric value in RPM.
