Lecture No. 3: Support Reactions in 3d || Engineering Mechanics - Statics

In three-dimensional structural analysis, determining support reactions involves creating a free body diagram of the entire structure, identifying support types, and applying equilibrium equations to solve for unknown reactions. These equations include force and moment equilibrium in three dimensions, ensuring that the structure remains stable and in balance. By resolving support reactions into their components and solving for unknowns, engineers can accurately assess the forces and moments exerted at support points, critical for designing stable and resilient structures under various loading conditions.
