BELL CRANK Meaning and
Definition
-
A bell crank is a mechanical device or linkage consisting of a pivoted lever or arm with two arms that are connected at an angle. It is usually in the shape of a "V" or an "L", resembling the outline of a bell or a crank handle. The purpose of a bell crank is to change the direction of motion or force between two different points.
In mechanical engineering and machinery, a bell crank is commonly used to transmit motion or force in a different direction. This is achieved by applying an input force on one arm, also known as the "input arm", which then causes a corresponding output force to be produced on the other arm, known as the "output arm". As a result, the motion or force is directed in a completely different direction without much loss in efficiency.
Bell cranks can be found in various applications, such as in automotive control systems, aircraft control surfaces, and even in simple household items like bicycles. They are designed to efficiently transfer power or motion while minimizing the need for complex mechanisms or excessive space.
Overall, a bell crank is a versatile and practical mechanical linkage that allows for the change in direction of motion or force, making it an essential component in many engineering systems.

Etymology of BELL CRANK
The word "bell crank" originated from the combination of two separate terms: "bell" and "crank".
The term "bell" refers to a hollow metallic object that produces a ringing sound when struck. It is believed to have derived from the Old English word "belle", which shares roots with the Middle Low German "belle", and Middle Dutch "belle". The word "bell" has been used to describe various objects related to sound production, such as church bells or handbells.
On the other hand, the term "crank" comes from the Old Norse word "krankr", meaning "bent". This word eventually made its way into Middle English and referred to any bent or crooked device or tool. In engineering contexts, a crank is a mechanical device used to convert circular motion into reciprocating motion or vice versa.
