Exercises

The topics listed above will be reinforced weekly in exersices and self-study exercises. In doing so, the exercises revisit the theory of the lecture and apply it directly to solve common mechanism design problems. Problems are solved graphically or computationally. Each exercise is concluded with knowledge questions to back up what has been learned. The self-study exercises give the opportunity to apply the learned methods in the geometry program GeoGebra and thus to get to know a suitable software product. The supervision of the self-study exercises is carried out at eye level by student assistants.
