Mechanical Systems: Assembly Techniques

This lecture covers various assembly techniques used in mechanical systems, including bolted joints, brazing, welding, and gluing. It explains the characteristics, uses, and processes of each technique, such as the types of joints, materials involved, and specific applications. The instructor discusses the principles of tightening and loosening nuts, the behavior of screws under axial forces, and the concept of self-locking in screw-nut assemblies. Additionally, the lecture explores the efficiency of screw-nut systems and the transformation of work during assembly processes.
