What is a lever ?
A rigid bar or object that moves around a fixed fulcrum with 2 forces applied to it
8 of 15
What is mechanical advantage ?
Second class levers allow a large load to be moved with a relatively small amount of muscular effort
9 of 15
What is mechanical disadvantage ?
Third class levers can not lift such heavy loads , with the same amount of effort , as second class levers due to the postion of the fulcrum in relation to the effort and the load
