Engineering mechanics, especially statics is the backbone of all mechanical engineering disciplines. being comfortable with the concepts of statics is an essential component in your toolbox on your path to be a successful engineer. In this course we will go from understanding very basic concepts of physics like time, length and mass step by step through studying motion and working with forces and force components into understanding equilibrium of particles and bodiesAfter finishing the course you will be able to isolate mechanical subsystems and represent them with their free body diagram including the external forces acting on it and the reactions of the supports.the following concepts will be discussed in the courseSection one: The fundamentalsWhat is mechanicsThe building blocks of mechanics: Time, length and massMotion: Position, velocity and accelerationSection two: Newton LawsNewtons first law: What is there is no force?Newton's second law: What if there is a force? Newton's third law: What happens to objects that apply force?Equilibrium and working with forcesForceWeightEquilibrium of a particleBreaking forces into their components, working with a force as a vectorThe Moment of a forceEquilibrium of a bodyReactions and FBDReaction of smooth and rough surfacesFrictionReactions of supportsSmooth and rough surfacesRoller supports,Pinned connectionsFixed connectionsSliding supportsFree body diagram FBDthe course will be followed by three other courses as a part of a complete engineering mechanics modulewe are looking forward to have you in this engaging and rewarding course!
