In mechanics, a carriage refers to a wheeled conveyance designed for transporting goods or passengers, historically utilizing principles of structural engineering and traction. These systems are characterized by a frame supporting a body and attached axles designed to bear weight while facilitating movement over varied terrain. The design relies on specific mechanical components, including wheels, axles, and suspensions, which absorb shock and distribute load. Over time, the technology powering these conveyances has evolved from purely animal-drawn models to mechanically powered units, demonstrating advances in material science, mechanical efficiency, and locomotion systems.
