The subject Mechanics III - Dynamics covers basic mechanics under consideration of mass accelerations. The course includes kinematics as a theory of motion, in which the relationships between position, velocity and acceleration vectors in co-moving coordinate systems are presented. The subsequent kinetics deals with the derivation of equations of motion based on Newton's laws.

Gyroscopic equations and energy methods are developed and applied to dynamic systems. The course concludes with an introduction to the vibration theory of multi-body systems and continuous oscillators.

  • Principle of D'Alembert, Lagrange's equations

Additional Information

How does the event work?

While the focus of the plenary lecture is on imparting theoretical content, the latter are used in the plenary exercises to solve engineering problems. The plenary exercises are offered in German and English language.

The examination of the module is taken in electronic form on the computer. It is offered on
several dates during the semester vacation. The grade of an examination that has already been
passed can be improved by increasing the total number of points by a maximum of 6 bonus
points, which can be earned in bonus point tests during the semester.
