Simple machine inclined plane

A simple machine is a basic device used to make work easier. Work is the transfer of energy from one physical system to another. During this process, energy is not created, only transferred. There are six simple machines inclined plane, wedge, screw, lever, wheel and axle, and pulley. We discuss each simple machine separately in this chapter. If we combine two or more simple machines so that they function together to make work easier, the device is called a compound machine. A wheelbarrow is an example of a compound machine it incorporates two simple machines (the lever and the wheel and axle).

B.c.E. Inclined plane Inclined planes are simple machines and were used in building Egypt s pyramids. Pushing an object up a ramp requires less force than lifting it directly, although the use of a ramp requires that the load be pushed a longer distance. 

The mechanics of a screw is similar to two other simple machines, namely the inclined plane and the wedge. As shown in Fig. 2.1, a screw can be considered as an inclined plane wrapped around a cylinder. Similar to the inclined plane, the horizontal force F needed to raise a weight W is...
