They are used to engineer speed, distance, force and function.. Inclined Plane, Wedge, Screw, Lever, Wheel & Axle, Pulley.. By: . Shae. Anderson. What is a simple machine?. A simple device for altering the magnitude or direction of a force. . A simple machine has few or no moving parts.. By:. Drew Harris. Simple machines. The basic machines that make up other machines are called . simple machines. . There are six of them. They are lever, pulley, wheel and axle, inclined plane, screw, and wedge. All these machines help us move things by changing the size of the force applied, the direction of the force, or both at once. . Simple Machines. Simple Machines. The Six Simple Machines.

Machines. Lesson 7. A compound machine is a machine made of two or more simple machines. The complexity can range from being very simple to very complex. . Domestic . Machines. A . common example of a domestic compound machine is nail clippers. A nail clipper contains two levers. A second class lever and a third class lever. The cutting blades themselves are also simple machines as they are inclined planes. . 2013. Mousetrap . Car. 6. th. -8. th. Grade. - Distance. 9. th. -12. th. . Grade. - Accuracy.
