AbstractIntroduction to engineering mechanics: statics and elementary dynamics
ObjectiveStudents can solve problems of elementary engineering mechanics.
ContentBasic notions: position and velocitiy of particles, rigid bodies, planar motion, kinematics of rigid body, force, couple, power.
Statics: static equivalence, force-couple system, center of forces, centroid, principle of virtual power, equilibrium, constraints, statics, friction.
Dynamics: acceleration, inertial forces, d'Alembert's Principle, Newton's Second Law, principles of linear and angular momentum, equations of planar motion of rigid bodies.
