COURSE DEFINITION
This course starts with an introduction to basic concepts in mechanics. The lectures cover external forces, joints, static equilibrium; particle and rigid body equilibrium, friction, trusses. Calculations of first moment of area and moment of inertia are shown. Virtual work principle, kinematics, force, acceleration, motion and energy concepts are covered. Stress and strain, elastic properties of materials, Hooke's law, factor of safety, Mohr circle, fatigue, shear, bending, torsion and their applications in engineering design are discussed.
