Hey guys, new to the forum. I am wondering how to find what the maximum rpm of a flywheel could be. I was looking at stirling engines, and trying to compile all the equations that apply to calculate the rpm of the engine. I know the equation for the expansion of gas in the cylinders and the force applied to the pistons, however I know that as the flywheel starts turning, the energy carried with it and the continued force applied builds upon eachother until it reaches its maximum rpm. Excluding the impact of friction and drag, I was wondering how you calculate the max rpm.
