Simple Machines

Simple machines are basic devices that make work easier by changing the direction or amount of force needed to move objects. Examples include the lever, pulley, wheel and axle, inclined plane, screw, and wedge. They help us lift heavy loads, pull objects more easily, or cut with less effort. By understanding how these machines work, we can perform tasks more efficiently, reduce the physical effort required, and better design tools and systems for various applications. Simple machines are fundamental tools that have been used for thousands of years to simplify work.
