Joint geometry refers to the study of the shapes and angles formed at the connections between different parts of a structure, such as in buildings or machinery. It focuses on how these joints can affect the overall stability and functionality of the system. Understanding joint geometry is essential for engineers and architects to ensure that structures can withstand forces and loads. In joint geometry, various types of joints, such as hinges, bolts, and welds, are analyzed to determine their effectiveness. The angles and configurations of these joints play a crucial role in distributing stress and preventing failure. Proper design and analysis of joint geometry contribute to the safety and durability of engineered systems.
