Hello! How do you calculate or determine newton meter force requirement and rpm's for an electrical motor in the following example: A device that utilizes a shaft that is 2 inches in diameter and 6 feet length. It needs to be able to lift 10 pounds and distance of 7 feet in 6 seconds. I need to know the formulas to make these calculations and the requirements needed for this application? Thanks in advance for any assistance! Mr. Nice Guy.
