A Mechanical Joint is a connection between two or more components that allows for movement or flexibility while maintaining structural integrity. These joints are commonly used in various applications, such as in piping systems, where they can accommodate thermal expansion and contraction. Mechanical joints can be made using bolts, screws, or other fastening methods, ensuring a secure fit. Mechanical joints are essential in engineering and construction, as they help to distribute loads and reduce stress on materials. They can be found in structures like bridges and buildings, as well as in machinery and vehicles. Proper design and installation of mechanical joints are crucial for safety and performance.
