Handbook

An introductory subject in engineering mechanics dealing with Statics (the equilibrium of objects, structures and fluids) and Dynamics (the mechanics of bodies in motion). Topics include: (i) Statics - 2-D concurrent and non-concurrent force systems; resultant of forces; equilibrium of forces; friction; distributed forces; centre of gravity; centroids; internal actions; analysis of beams (shear force and bending moment diagrams); analysis of frames (determinancy, internal hinges); analysis of trusses (methods of joints and sections); cables; fluid statics including hydrostatic pressure, body forces, buoyancy, stability, and manometry; introduction to three dimensional statics. (ii) Dynamics - Laws governing continuity, energy and momentum; dynamics of particles; planar motion of rigid bodies; simple spring mass systems responding to forces of simple form. (iii) The concepts of stress and strain; principal stresses and an introduction to Mohr's circle of stress.
