Levers
fulcrum - the point where the lever pivots
load - the force exerted by the load
effort - the amount of force put in my the user
mechanical advantage
large amount of force exerted with small effort
load = MA x effort
velocity ratio
distance moved by effort = VR x distance moved by load
the distance the effort has to move compared to the load
Lever class 1
fulcrum is on the right side of the load
load is right on the left
effort is on the right
scissors
Lever class 2
effort is right on the left
fulcrum is right on the right
load is in the middle
wheelbarrow
Lever class 3
load is right on the left
effort is in the middle
fulcrum is on the right after the effort
tweezers
