## ENGG 125 - Engineering Mechanics and Thermodynamics

This course expands on concepts of statics, dynamics, and thermodynamics in the context of engineering practice. Statics is the branch of mechanics dealing with particles and rigid bodies that have zero acceleration and includes the analysis of loads (force, moment, and equilibrium conditions) and the physical properties of rigid bodies (e.g. frictional forces, centre of gravity, and moment of inertia). Dynamics is the branch of mechanics dealing with particles and rigid bodies that do not deform under the action of applied forces and have non-zero acceleration. Thermodynamics is the branch of physics concerned with the relationship between heat and other forms of energy and their transfer.
