- I need to know how much energy is required to turn a 4-foot diameter flywheel, weighing 40 lb, at a speed of 60 RPMs.
I know I'm probably overcomplicating this question, but I'm having a bit of difficulty coming up with a singular answer. I have a 4-foot diameter flywheel that I need to turn with an electric motor of an unknown horsepower. I say unknown because I I don't know what I need based upon the following criteria. 4 foot flywheel, weighing 40 lb, and I needed to turn at an RPM of RPMs. What size electric motor would I need in order to accomplish that. There will be no external force is applied upon the wheel once it starts turning, and it does not matter how long it takes to get to 60 RPMs
