Mechanical Advantage
Statements on Mechanical Advantage
Mechanical advantage is a measure of the force amplification achieved by using a machine or tool
The law of the lever is an example of mechanical advantage
Formula
Mechanical Advantage =
Output Force/Input Force
What Are Simple Machines?
Object created by human to make work easier
Performs some kind of task or work
Uses power to apply force and control motion
All types of simple machine
Inclined Plane
Lever
Pulley
Screw
Wedge
Wheel and Axle
Lever
First Class Lever - Fulcrum between load and effort
Second Class Lever - Load between fulcrum and effort
Third Class Lever - Effort between fulcrum and load
Deriving Mechanical Advantage Using Principles of Moment
Taking moment about the Fulcrum, by the Principle of Moments, in equilibrium, where F is the force and D is the distance between the force and the pivot.
Sum of anticlockwise moments = Sum of clockwise moments
F1 ✕ D1 = F2 ✕ D2
