Introduction (Part 1) What is mechanics  The science that describes and predicts the conditions of rest or motion of bodies under the action of forces.  What happens to this body o Does it move (Dynamic) o Does it stay still (Static) o Does it deform/ deflect Mechanics is Comprised of Multiple Topics  Rigid bodies o Statics o Dynamics  Deformable bodies o Mechanics of materials  Fluids o Incompressible o Compressible We Will Focus on Rigid Bodies  Statics deals with bodies at rest.  Dynamics deals with bodies in motion. Mechanics is the Foundation for Mechanical Engineering. Introduction (Part 2) Fundamental Concepts and Pri
