For those non-mechanical engineers who have heard the phrase “rack and pinion” but are unfamiliar with the term, Wikipedia defines it: A rack and pinion is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion. A circular gear called “the pinion” engages teeth on a linear “gear” bar called “the rack”; rotational motion applied to […]
