Linkage arms are rigid structural elements used in mechanical systems to connect rotating or pivoting components, enabling controlled motion transfer, force amplification, or directional changes. They function as part of four-bar linkages, parallel mechanisms, or complex kinematic chains in industrial machinery.

Linkage arms operate on kinematic principles, typically forming rigid-body mechanisms where rotational motion at one pivot point creates predictable motion at another. They maintain fixed distances between connection points while allowing angular movement, often converting rotary motion into linear or oscillating motion through geometric relationships.
