welcome to my page on 3rd class levers what is a 3rd Class lever? A 3rd Class lever is when the EFFORT or FORCE is in the middle, the fulcrum is on one side and the load is on the other. An example would be... TWEEZERS... or a baseball bat. Another example of a 3rd class lever is a fishing rod
A class 3 lever always gives a mechanical advantage less than 1 because the load arm is always longer than the effort arm. MA= Effort armdivided by load arm. So MA will be less than 1.
