In the most general sense, a machine is any device that can be used to perform a task. In the mechanical sense, a machine is a device for transmitting work from one location to another. A bicycle is a machine. There are six simple machines. They are as follows: lever, wheel, pulley, incline plane, wedge and screw. This tutorial will cover the first three. Simple machines can give you a mechanical advantage—in other words they allow you to spread the force you apply to move an object over a distance. Design and build your own simple machine or investigate how they work. While simple machines are called simple, learn that they make many things happen, including your bike go around. Simple machines are levers, inclined planes (ramps), screws, wheels/axles, pulleys, and wedges. There are six simple machines: the wheel and axle, lever, inclined plane, pulley, screw, and wedge. Wheel and Axle. The wheel and axle makes transporting heavy goods easier and helps people travel distances. A wheel has a small footprint, so it reduces friction when you move an object over a surface. 9.3 Simple Machines - Physics | OpenStax 167 interactive simulations. 121 language translations. 3433 teacher-submitted lessons.

The simple machine shown in Figure 9.8 is called a wheel and axle. It is actually a form of lever. The difference is that the effort arm can rotate in a complete circle around the fulcrum, which is the center of the axle. Force applied to the outside of the wheel causes a greater force to be applied to the rope that is wrapped around the axle.
