LEVER:
First Class Lever:
A 1st class lever is a lever with its Fulcrum in between the Effort and the Load. An example is the scissors and a roller coasters and glow sticks! A hint to remember:
JUST REMEMBER FLE 123 1= fulcrum in the middle 2=Load in the middle 3=Effort
A Class-I lever is a lever set up like a see-saw ... with the effort and
the load located at opposite ends, and the pivot between them.
A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. There are 3 class levers: 1st, 2nd, & 3rd.
Second Class Lever:
A Class-II lever has the effort at the other end, and the load is in the middle, just like a wheel barrow.
Third Class Lever:
A Class-III lever, the load is at the other end, and the effort is in the middle. An example of this would be A shovel.
