What are mathematical expressions for moments of inertia due to pressure and crank on a cylinder piston?
Pressure and crank do not affect moment of inertia. The moment of inertia of an engine can only be measured on a test bench. To measure the moment of inertia of an engine, you have to apply a constant torque and measure the angular acceleration. Friction must be factored in. It should be allowed to turn freely. Then apply the following differential equation. T(t) = M w’ + F w T: torque M: moment of inertia F: viscous friction w: angular velocity w’: angular acceleration _________________________________ Dear sauberss, pressure on a piston and crankshaft do not create or generate moment of inertia. Only rotating mass create moment of inertia. Pressure only creates torque. .
