Review of Statics

This lecture provides a detailed review of static systems, focusing on the use of a 4-step problem-solving approach to analyze internal and external forces in structures. Starting with conceptualization and categorization, the lecture progresses to analyzing external reactions and internal forces using statics sign conventions. The final step involves finalizing the results and understanding how to determine internal forces using either left- or right-hand free body diagrams. Examples include finding reaction forces and member forces in truss structures through equilibrium analysis and method of joints. The lecture emphasizes the importance of plotting variations of forces along the length of beams for design purposes.
