Handlebar lever is rotated at an angle of 90. To push the brake block against the wheel rim 2 Figure 1: Typical example of a bell crank 2 2.0 Initial Load Case. Figure 2: CAD Model of In-line Bell crank thus the results are taken to be as Figure 2 shows the design of the in-line bell crank. The bell crank is expected to be made of steel. In this project Optimum Design of Bell Crank Lever was designed by considering some properties like Density, Young's modulus, Ultimate tensile strength, Yield Strength, Shear modulus, Cost.

What is a lever?
A lever is a rigid bar that pivots about a fulcrum. It transmits an input motion and force, (the effort) through the lever pivoting on a fulcrum to a resistance force called a load.

Load
The load is anything that is being moved by a lever.
Effort force
Design Of Bell Crank Lever
The effort force is the energy applied to a lever to move a load.
Fulcrum
Bell Crank Assembly
The fulcrum is the point at which the lever pivots. A lever may rest on a fulcrum or it may swivel on an axle, e.g. a see-saw (class 1 lever) and a wheel barrow (class 2 lever).
Classes of lever
There are three classes of levers. Each class of lever has the load and effort force in specific positions relative to the fulcrum.
Class 1 lever
A Class 1 lever has the fulcrum between the load and the effort force.
Class 2 lever
A Class 2 lever has the load between the fulcrum and the effort force.
Class 3 lever
A Class 3 has the effort force between the load and the fulcrum.
Design Procedure Of Bell Crank Lever Pdf
Bell Crank LeverA 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. |
What Is A Bell Crank Lever
CantileverA cantilever is a beam that is fixed at one end only. Load is applied to the unsupported end. A cantilever may be classified as a type of Class 1 lever as fulcrum is between the effort force and the load. |
