Mechanics of Springs

This lecture covers the mechanics of springs, focusing on the behavior of two connected springs and the forces exerted on them. The instructor explains the positions and elongations of the springs, as well as the forces exerted by each spring. Different methods are employed to analyze the forces and elongations in the system. The lecture also discusses the equivalent spring elongation and the forces acting on different masses in the system. Various equations of motion are derived to describe the behavior of the springs and masses in different scenarios.
