The lectures and tutorials take place in presence. Further information can be found in the Ilias-course of the lecture. There you will also find a schedule with all lectures and the corresponding tutorials.

An exam prerequisite will be obligatory. Further information to the type of prerequisite will follow in the Ilias course.

Learning target:

Engineering mechanics III deals with kinematics and kinetics of system of particles as well as plane motion of rigid bodies under the influence of forces and moments. Equations of motion are derived using Newton's axiom and the principle of moment of momentum. As applications the equations of motion are derived for systems of particles and simple systems of rigid bodies, including impact problems. Therefore, the course aims at applying Newton-Euler's equations, Principle of moment and principle of moment of momentum as well as principle of energy conservation for simple mechanical engineering problems.

Content:

• Kinetics of a particle: Newton's axiom, Principle of d'Alembert, work of a force, kinetic and potential energies, principle of linear momentum, principle of moment of momentum, kinetics in moving reference systems 
• Systems of particles: Principle of center of mass, Principle of moment of momentum, impacts between particles, systems with variable mass, applications.
• Plain motion of rigid bodies:
  Pure translation, pure rotation, general plain motion. Instantaneous center of rotation, Kinetics, moment of momentum, principle of work and principle of energy conservation for a rotation around a space-fixed axis.
