Simple Machine: The Screw

The document discusses the simple machine known as the screw. It explains that a screw is a long post wrapped with metal threads, and is a type of inclined plane wrapped around a cylinder. Screws help hold things together and make work easier to do by providing an inclined surface that reduces the amount of force needed, though more turns may be required with screws that have threads close together versus those with threads farther apart.

Simple Machines: The Screw
Simple Machines: The Screw The screw is one kind of simple machine. Screws help us hold things together.
Simple Machines: The Screw A screw is a long post that is wrapped with metal threads. A screw is actually a kind of inclined plane.
Simple Machines: The Screw It is an inclined plane that is wrapped around a cylinder.
Simple Machines: The Screw If you follow the threads on a screw, they will form a long ramp from the bottom of the screw to the top of the screw.
Simple Machines: The Screw The threads on the screw may be close together. The threads may be farther apart.
Simple Machines: The Screw A screw with threads that are close together makes work easy to do. It forms a long inclined plane.
Simple Machines: The Screw The work is easy to do, but you will have to turn the screw many times.
Simple Machines: The Screw A screw with threads that are farther apart forms a shorter inclined plane.
Simple Machines: The Screw The work is harder to do, but you will not have to turn the screw as many times.
