Simple Machines 3 Using Wheels and Axles In some devices, the input force is used to turn the wheel and the output force is exerted by the axle. Because the wheel is larger than the axle, the mechanical advantage is greater than one. So the output force is greater than the input force....
The lever, the pulley, and the inclined plane The wheel and axle, the wedge, and the screw are modifications of these simple machines. 1. LEVER A simple machine made with a bar that pivots (move) around a fixed point called a fulcrum Low Mechanical Advantage High Mechanical Advantage 3rd ...
This program shows how the six simple machines can be found in use in very complicated machines. The six simple machines are the basis for all other machines. Examples of compound machines, machines that use two or more simple machines, are presented and analyzed. View CitationsPrepare...
Throughout history, humans have developed several simple machines to make work easier. The most notable of these are known as the "six simple machines": the wheel and axle, the lever, the inclined plane, the pulley, the screw, and the wedge, although the latter three are actually just ext...
