Bell Crank

A bell crank is a mechanical device that is used to change the direction of motion or force in a system. It consists of a pivoting arm or lever that is connected to two or more rods or linkages. When one end of the bell crank is moved, it causes the other end to move in a different direction.

Bell cranks are commonly used in various applications, including mechanical systems, automotive systems, aircraft control systems, and machinery. They are often used to transmit motion or force around obstacles or to change the direction of motion in a system.

The design of a bell crank can vary depending on the specific application and requirements. Some bell cranks have a simple L-shaped design, while others may have a more complex configuration with multiple arms and linkages.

Overall, bell cranks are versatile mechanical devices that play an important role in transmitting motion and force in various systems.
