Dersin Tanımı

Engineering Mechanics, the oldest branch of physics, interests with the effects of forces on bodies in its most general sense, e.g. systems performing specific movements, structures carrying loads in certain environments, ever-standing buildings, etc. Last term you studied the equilibrium of stationary rigid bodies within the Statics course, and developed the foundational knowledge, ideas and skills for Engineering Mechanics. By means of Dynamics, we’ll raise our vantage point and look at the more challenging problem of bodies in motion. Throughout the course, first the motion itself will be investigated without getting interest into the causes behind (kinematics), then by calling the forces into the scene, the equilibrium of moving bodies will be studied (kinetics), so that we can generate the equation of motion, enabling us to see the trajectory of a body at once. At this part of the course, we’ll encounter several different approaches, each bringing new perspectives.
