the fulcrum F and the Load (L) are at the two ends of levers and the effort (E) is somewhere in between the fulcrum F and the load(L) as shown in figure.
The fulcrum F and effort E are placed at the two end of the levers and the load L placed somewhere in between point of E and L. Effort arm is always larger ...
The fulcrum F is in between the effort E and the load L as shown in figure. The fulcrum F need not be at the mid-point between the load L and the effort E.
Levers are the simple machines which used in our daily life. Most of the case, we don't know about these machines but we used it.
A machine is a device by which we can either overcome a large resistive force at some point by applying a small force at a convenient point.
