Lecture
  • Motion of a particle in a moving reference frame. Velocity and acceleration of a particle in a resultant motion. Coriolis acceleration. Dynamics of relative motion.
  • Dynamics of a rigid body: kinetic energy, momentum and angular momentum laws. Dynamics of a rigid body in translation, plane motion (incl. Dynamics of vehicles), rotation about fixed axis (incl. bearing reactions of unbalancerd rotors) and rotation about fixed point (incl. gyroscopic effect).
  • Elements of analytical mechanics: constraints and generalized coordinates of multibody systems, virtual displacements, virtual work and d’Alembert’s principles. Lagrange’s equations.
  • Impact phenomena. Collision of a particle with a fixed barrier. Collision of two particles. Impact center of a body. Collision of two bodies in plane motions.
  • Dynamics of a particle with variable mass. Equation of motion of a particle with continously varying mass. Examples and applications.
