Equilibrium in the Plane

This lecture covers the concept of equilibrium in the plane, focusing on the balance and friction of skiers. Students are required to draw force diagrams for skiers, position forces, and indicate their values. The lecture emphasizes the importance of extending forces in polygons and using subsystems to express balance. It also includes instructions for printing exercise sheets and managing page layouts. Additionally, the lecture provides information on structural courses at EPFL, including topics like beams, slabs, and loads. Students are encouraged to engage with course materials and exercises to develop an intuitive understanding of structures.
