The Lever Levers conserve torque, use this
to your advantage since you can reduce the force needed by increasing the distance. |
|
The Pulley Pulleys can change the direction of a forceand reduce the force required(at the cost of increased distance) |
|
Screw Converts rotational motion to linear motion. Yay Archimedes! |
|
Incline Plane Incline Planes reduce force at the cost of distance....again. |
|
Wheel and Axle A simple machine consisting of an axle to which a wheel is fastened so that torque applied to the wheel winds a rope or chain onto the axle, yielding a mechanical advantage equal to the ratio of the diameter of the wheel to that of the axle. |
|
Wedge Basically a portable inclined plane, but this time you shove it into something rather than use it as a ramp. |
Here are all 6 simple machines in a Rube Goldberg. Just watch the first half:
