Structural Analysis: Internal Forces and Reactions

This lecture discusses the results of two exercises, analyzing the performance of students in determining internal forces and reactions in static structures. The instructor highlights key concepts such as isotaticity, action-reaction principles, and the use of virtual work to calculate reactions. Students are guided through the process of determining internal forces and reactions step by step, emphasizing the importance of understanding the structural stability and equilibrium. Practical examples and exercises are used to illustrate the application of theoretical concepts in solving engineering problems.
