    Screw thread

    A mechanism that converts rotating motion into linear motion. Imagine a screw going into a piece of wood. The rotation of the screw causes it to move in a straight line.

    Peg and slot

    A mechanism that converts reciprocating motion into rotating motion, like a piston in a car engine.

    Crank and Link

    A mechanism that converts rotating motion into reciprocating motion. Imagine a car engine where the rotation of the crankshaft makes the piston move up and down.

    Cam and Slide Follower

    A mechanism that converts rotating motion to reciprocating motion. Picture a car engine where the rotating camshaft pushes the piston up and down.

    Peg and slot (oscillating to rotating)

    A mechanism that converts oscillating motion into rotating motion. Imagine a seesaw. The up-and-down motion of the seesaw causes the wheel to rotate.
