Stress Components and Equilibrium Equations in Strength of Materials
This covers the analysis of stress at a point in a deformable body: how the resultant internal stress on a cut section decomposes into a normal-stress component and in-plane shearing-stress components, how the free-body-diagram method isolates a body or part of a body under external and internal (reactive) forces to enforce Newtonian equilibrium, and how these ideas combine into the stress tensor and the differential equations of equilibrium. It belongs to strength of materials (mechanics of deformable solids), building on Newtonian statics (force and moment equilibrium) and material equilibrium/deformation behavior.
