Document Summary
Introduction to engineering mechanics: lecture intended learning outcomes; Describing the basic idealisations of mechanics such as rigid body, continuum, particle and point force, Di erentiating between branches of mechanics: engineering mechanics; De nition; mechanics is a branch of physical sciences that is concerned with the state of rest or motion of bodies that are subjected to the action of forces. Branches of mechanics; mechanics can be classi ed into two sub types: mechanics of solids; can be classi ed into two sub types; i. Rigid body dynamics; can be classi ed into two sub types: statics, dynamics, deformable body mechanics, mechanics of materials, mechanics of fluids; can be classi ed into two sub types; i. ii. Fluid dynamics: fundamental concepts and si units; Length( l ); unit is meter (m). Force (f); unit is newton (n): 1 newton is equal to a force required to give 1 kilogram of mass an acceleration of 1m/s2 (1n = kg-m/s2).
