Question

Quizplus · Accepted Answer

An eccentric cam has a circular disk with the axle placed off-center, which results in a smooth, harmonic, linear output motion to the follower. A pear-shaped cam has a more complex shape and does not necessarily provide a smooth linear motion. A roller cam uses a cylindrical or spherical roller instead of a follower and does not have the same off-center design as an eccentric cam. A twin cam is a type of engine design and is not related to cams with an off-center axle.
