5.1 Calculating the average equivalent moment of inertia of the connecting rod and piston

The average equivalent moment of inertia of the connecting rod and piston is calculated as I _eq (kg.m ² ), assuming that the connections are free of play and the parts are dimensionally stable. In the usual way, this average moment of inertia is represented by a concentrated mass M _e (kg) placed on the crankpin axis at a distance R (m) from the crankshaft axis. We have : I _eq = M _e R ²

From the parameters...
