Bell Crank Lever:
A bell crank lever is an angled Class 1 lever. It is a Class 1 lever because the fulcrum is between the load and the effort force. The bell crank lever is used when the effort force must be at an angle, usually a right angle, to the load.

Examples include:
1) FBLE - Seesaws.
2) LBEF - wheelbarrow.
3) EBFL - sugar tong or tongs generally.

Short tricks:
1. FBLE (fulcrum b/w load and effort) this is 1st type lever.
2. LBEF (load b/w effort and fulcrum).
3. EBFL (effort b/w load and fulcrum) that is 3rd type levers.

@Bhargav.
The type 1 lever fulcrum is in between load and effort (effort is near to fulcrum).
The type 2 lever load in between fulcrum and effort.
The type 3 lever effort in between fulcrum and load.

The type 2 lever load in between fulcrum and effort.
The type 3 lever effort in between fulcrum and load.
