the simple machine

A screw is one of the six simple machines. Screws convert rotational force (aka torque) to linear force. Screws do this by means of a single helical plane wrapped around the shaft of the screws. Normally, the use of another tool is required to cause this force conversion.

A screw is a shaft with a helical groove or thread formed on its surface. Its main uses are as a threaded fastener used to hold objects together, and as a simple machine used to translate torque into linear force. It can also be defined as an inclined plane wrapped around a shaft.

"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."

A) It's like a nail, only with threads like a bolt...
B) The propellar that you see on the back of a submarine
C) Also a tool you use (example is a cork screw) In larger sizes it's used for mining. In smaller sizes it's used to drill through wood and other types of materials like a cork or metal. The bits for a drill that are used to make holes. That's the most basic form of a screw that I can think of.
