Engineering Mechanics

Statics and dynamics — how loads flow through structures. The mechanics every civil engineer relies on: loads and statics, force systems and trusses, equilibrium of beams and frames, and the dynamics behind vibrations, impact and moving loads.

• Statics — Statics is the study of bodies at rest under balanced forces — the foundation of every structure. Learn loads on structures (dead, live, wind, snow, seismic), idealisation, free-body diagrams, supports, internal forces and a systematic method for solving statics problems.
• Force Systems — Force systems classify how forces act together: collinear, concurrent, parallel and general. Learn resultants and their location, distributed loads, equivalent force–couple systems, and truss analysis by joints and sections.
• Equilibrium — A body in equilibrium has no net force and no net moment. Learn free-body diagrams, support types and their reactions, solving beam and bracket reactions, and shear-force and bending-moment diagrams.
• Dynamics — Dynamics explains why motion happens. Learn Newton's laws, F = ma, work–energy and power, impulse–momentum, rotational dynamics T = Iα, and how they size motors, brakes and lifting systems.
