Simple Machines & Levers
Machine (Make easy for people to do work)
Inclined plane
The force required can be reduced by increasing the distance over which the force must be applied
Lever
Load: the object lifting
Fulcrum: point at which the lever pivots
Effort: the force applied to make the object move
1st: Fulcrum between load and effort
2nd: Load between fulcrum and effort
3nd: Effort between fulcrum and load
Screw
Convert rotational motion into linear motion
The strength of a screw's hold depends on the width of the threads and the distance between them. The closer and wider the thread, the stronger the hold will be
Pulley
Increase the number of pulleys, a greater amount of rope.
Wheel & axle
Reduce the friction making it easier to move
Wedge
The inclined angle is small, the wedge fields more work and may do the job faster, than a wedge with a wider angle
Mechanical advantage is a measure of the force amplification achieved by using a machine or tool
Mechanical advantage: Output force/Input force
Load/Effort
Moment
Clockwise & Anticlockwise direction
F x D
Mechanical advantage: F1/F2
Mechanical advantage: D2/D1
