Draw free-body diagrams and write the corresponding equations of equilibrium.
Solve equilibrium equations for unknown force components.
Construct shearing force and bending moment diagrams for simple beams.
Solve problems involving dry friction.
Determine whether a system is statically determinate.
Locate centroid of areas, and calculate area moments of inertia.
