Screw (simple machine)
Encyclopedia : S : SC : SCR : Screw (simple machine)
A screw is one of the six simple machines. A simple screw is a helical inclined plane. A screw can convert a rotational force (torque) to a linear force and vice versa. The ratio of threading determines the mechanical advantage of the machine.
Archimedes' screws and worm gears are examples of this machine.
