- Mechanics is the study of forces and their effects on bodies at rest or in motion. - MECHANICS - FLUID MECHANICS - FLUID STATICS (hydrostatics) - FLUID DYNAMICS (hydrodynamics) - SOLID MECHANICS - STATICS - DYNAMICS - Statics is a discipline in the field of mechanics in which we study the effects of forces on solid bodies at rest. We assume these solid bodies are rigid , that is they do not deform (stretch, compress, bend, flex or twist).
