SIMPLE MACHINES

This is an interesting compilation of simple machines. These simple machines use the fundamental law of forces and mechanics to carry out very simple movements. These in turn can be used to create machines that we see around us in our everyday lives. Pulley is a simple machine and comprises of a wheel on a fixed axle, with a groove along the edges to guide a rope or cable. The lever is one of the most basic forms of a machine. They help us lift loads with lesser effort. Even though this looks simple there are many things going on in order to lift the object easily. An inclined plane is a ramp that assists moving heavy objects up and down heights. It is a plane surface set at an angle, other than a right angle, against a horizontal surface. A screw is one of the most commonly used mechanical devices in the world. It is machine that converts rotational motion into linear motion. The wedge is the active twin of the inclined plane and one of the six classical simple machines. Unlike an inclined plane, which is stationary, a wedge does useful work by moving.
