Knuckle Joint

A knuckle joint is a mechanical connection between two rods, allowing angular movement while restricting axial movement. It consists of a pin and two arms, one of which has a spherical end that fits into a socket on the other arm. This design permits flexibility, making it useful in structures that require bending or rotating motion, such as crane hooks. In engineering, knuckle joints are used to manage loads, distribute forces, and accommodate variable angles, contributing to the adaptability and durability of mechanical systems.
