Necessary members of cam and follower mechanism are. Slider-crank mechanism, arrangement of mechanical parts designed to convert straight-line motion to rotary motion, as in a reciprocating piston engine, or to convert rotary motion to straight-line motion, as in a reciprocating piston pump. How do cranks work? They will learn that a cam mechanism is a linkage system which has a follower to convert rotary movement to linear movement, and explore different examples of these in moving toys.
