First off thanks in advance for any help given here. Hope you don`t mind bullet points. Makes it easy for me. I`m building a type of flywheel that consist of: 1) A single rod 2 ft across. Axel in the middle. 2) A 2 lb weight on both ends of the arm. 3) Rod weight 1 lb. 4) There will be a constaint 20 rpms applied to the flywheel at the 1 in axel. 5) A speed change from 20 rpms to 80 rpms (engaged gearing system) will occure for 1/2 rpm. The question is: How many foot pounds of force is needed to make the change from 20 rpms to 80 rpms? As a side note all force is applied to the 1 in axel.
