connections and joints

Connections and joints are points where different parts of a structure or object meet and move or stay fixed together. Connections link components, often providing support or transfer of forces. Joints are specific types of connections allowing movement (like in your joints—elbows, knees) or securing parts in place. They enable flexibility, folding, or stability, depending on their design. In engineering, understanding how joints work helps in designing safe, durable structures and machines that can move smoothly or bear loads effectively.
