What is a primary function of hinges in mechanical design?

• A. To support electrical connections
• B. To allow rotation between two parts
• C. To provide airtight seals
• D. To hold items in place

Answer: (B)

The primary function of hinges in mechanical design is to allow rotation between two parts. Hinges enable two components to pivot relative to each other around a fixed axis, facilitating movement and operation. For instance, in a door hinge, the hinge allows the door to swing open and closed while remaining attached to the door frame. This rotational movement is crucial in various applications, such as cabinets, gates, and machinery, where controlled movement is required. Understanding this function highlights the significance of hinges in creating assemblies that require a degree of mobility while maintaining structural integrity. Other functions, such as supporting electrical connections, providing airtight seals, or holding items in place, are not the primary purposes of hinges and pertain to other mechanical components or design elements.
