mechanics
- Newton's Laws of Motion
The three laws of classical mechanics — inertia, F = ma, and action–reaction — that form the basis of classical physics. - Stress and Strain
The two fundamental measures of how materials respond to loads: force per unit area and fractional deformation. - Structural Loads and Beam Bending
How engineers classify loads, and how bending moment and deflection are computed for beams — the backbone of structural design.
