Learning outcomes:
After successfully completing this module, students will have consolidated, deepened and expanded their understanding of mechanical relationships with regard to the “description and calculation of the spatial motion of point masses and rigid bodies” and “collision processes”. They will be able to describe and calculate vibrations of machine parts. They will be able to analyze engineering problems of intermediate complexity in the field of dynamics, to reduce them to basic physical principles and work out targeted solutions, so that they can design and dimension moving machines or machines with moving elements.
