Q:

# What simple machines belong to the inclined plane family?

A:

The ramp, wedge and screw are simple machines belonging to the inclined plane family. Inclined planes makes it easier to move an object. Lifting an object vertically requires a great amount of force. Using a ramp requires less force, but also requires the object to be moved a greater distance.

The two families of simple machines are the inclined plane and the lever. The lever family includes the lever, the wheel and axle, and the pulley. Levers move and inclined planes remain stationary.

Ramps are the most basic type of inclined plane. This group also includes the wedge and screw. The wedge is two inclined planes placed back to back. Wedges provide several advantages. They provide a grip for things to be lifted and can be used to hold things in place. Conversely they may also be used to push things apart. Doorstops and chisels are both examples of wedges.

When an inclined plane is wrapped around a cylinder, it is called a screw. The inclined plane is the threads of the screw. Threads climb up the central cylinder in the same way an inclined plane angles up from the ground. Screws are used to move or raise liquids or solids and to fasten or press objects together.

According to PBS, Galileo's inclined plane was an experiment performed to test the effects of gravity on falling objects. Galileo's inclined plane experiment eventually proved that in the absence of outside forces, gravity causes all objects to fall at an increasing rate.

An inclined plane makes work easier by reducing the exertion needed for the job while increasing the distance over which that exertion is maintained. The angle at which a load is lifted determines the amount of exertion needed to lift it. Lifting a load straight overhead requires the most exertion.

The six simple machines are wedges, screws, levers, pulleys, wheels and inclined planes. Simple machines make work easier by transferring force from one place to another, changing the direction of a force, increasing a force, increasing the distance of a force or increasing speed of a force. All of these forces move mass.
