Design of lever involves determination of various dimensions of the lever for a specified load or output force required. For a specified load or output force desired, effort required can be calculated using principle of moments. Due to these forces, arms of the lever are subjected to.

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

The effort force is the energy applied to a lever to move a load.

Fulcrum

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

Use Of Bell Crank Lever Design

A Class 3 has the effort force between the load and the fulcrum. Kal equip 3000 digital multimeter manual.

Design Procedure Of Bell Crank Lever

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.

Design Of Bell Crank Lever System

Cantilever

A 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.

Parametric design charts are proposed for the central-lever steering linkage, generated for simplified reference configuration mechanisms, the geometry of which is defined by only four parameters. This highlights the fact, yet not generally acknowledged, that the steering law ensured by a mechanism with adjacent central joints (known as bell crank mechanism), can be identically generated by a triple central joint variant of the same. Particular configurations are identified in which the length of the central lever does not affect the wheel-to-wheel transmission function of the mechanism, permitting a simplified synthesis for the cases in which the maximum stroke of the input member is imposed as a design specification.
