Simple Machines & Levers

-
Lever Comprises of:
-Load (to be moved)
-Fulcrum(Point where the rigid body pivots on at any position along the rigid body)
-Long Rigid Body(The long rigid body forms part of the lever)
-Effort(Where the human applies force)
3 Classes of Levers
Second Class Lever (Wheel Barrow, Bottle Opener)
Third Class Lever (Thongs, Mop)
First Class Lever (Scissors, See-Saw)

Determining whether the lever system will result in clockwise or anti-clock wise moment through moments.
Sum of anticlockwise moments = Sum of clockwise moments
F1 ✕ D1 = F2 ✕ D2
where F is the force and D is the distance between the force and the pivot
Finding the Equilibrium requires the distance and force multiplied together to be equal on both clockwise and counter-clockwise
