Simple Machines

A simple machine is a mechanical device that is used to change the direction, magnitude, or intensity of a force. It is designed to make it easier to perform work by reducing the amount of force that is required. There are six types of simple machines: lever, pulley, wheel and axle, inclined plane, wedge, and screw. Simple machines are an important concept in physics and engineering and are used in a wide range of applications, including construction, manufacturing, and transportation 

Types of simple machines : 

Lever: A lever is a bar that is pivotally mounted on a fixed point, or fulcrum. It is used to change the direction or magnitude of a force.


Pulley: A pulley is a simple machine that consists of a grooved wheel and a rope or cord. It is used to change the direction of a force and to lift or move objects.


Wheel and axle: A wheel and axle consists of a wheel that is mounted on an axle. It is used to change the direction of a force and to create rotary motion.


Inclined plane: An inclined plane is a flat surface that is angled in relation to the ground. It is used to reduce the force needed to lift an object by increasing the distance over which the force is applied.


Wedge: A wedge is a triangular-shaped object that is used to split or cut materials by applying a force.


Screw: A screw is a cylindrical object with a helical groove that is used to hold objects together or to lift or move them
