Simple Machines
Levers
A rigid bar that is free to pivot, or rotate, on a fixed point called the fulcrum.
-
Mechanical Advantage
Divide the distance from the fulcrum tot he input force by the distance from the fulcrum to the output force.
Ideal mechanical advantage = distance form fulcrum to input force / distance from fulcrum to output force
Levers are classified according to the location of the fulcrum relative to the input and output force.

Screws
-
How It Works
-
As the threads of a screw turn, they exert an output force on the object, pulling the screw into the object.
-
-
Wheel and Axle
-
How It Works
Because the wheel is larger than the shaft, or axle, the axle rotates and exerts a large output force. the wheel and axle increases your force, but you must exert your force over a long distance.
-
Pulley
-
How It Works
You use input force to pull on one end of the pulley so that way the other end move upward which is the output force.

There are six basic kinds of simple machines: inclined plane, pulley, wheel and axle, screw, and lever.
