What are Simple Machines?""
Simple machines are tools that make our lives easier. These tools enable us to use less energy and less force to do work."""

• Lever • Incline Plane • Wedge • Screw • Pulley • Wheel & Axle
There are six types of Simple
Machines?
Lever
There are two parts that make up the lever. The bar, which is called the“arm” and the fulcrum or pivot point. The lever helps us lift things easily.

Examples of the Screw
These screws help hold these objects together. Can you think what else screws hold together?

SWING HINGES
Pulley A Pulley is a made up from a wheel that is wrapped with a cord or rope. A pulley changes the direction of force and makes it easy to hoist or lift objects.
