Noticed this particularly in cars with large engines. Is it something to do with torque? The forces caused by the driveshaft spinning?
In: Engineering
It’s caused by the torque of the rotaing mass of the engine. Even when the transmission isn’t engaged, the flywheel behind the engine is still spinning.
Most automotive engine flywheels rotate (as viewed from the flywheel) counterclockwise – left. According to Newton’s law, the engine and everything it’s attached to will want to rotate in the opposite direction- right.
