Many titles have already been published in the field of machine elements. A wide range of works is available, both in terms of the breadth of presentation and the focused, in-depth treatment of individual topics. So what are the focal points of this book? In industrial practice, there is an increasing demand for system thinking. The consequence for engineers in mechanical engineering and related fields is the interconnected application of knowledge, for example, from the areas of technical mechanics, machine elements, drive technology, technical drawing, and design. This work aims to address this requirement at least in part through the tasks, solutions, and comments presented. For learning in a subject area, it is important to approach tasks independently and to seek an appropriate solution path individually. After intensive work on a task, it is then significant to have a possible solution path available. Based on this solution, different approaches can be explored, and previously unknown aspects can be developed. Accordingly, this book presents solution paths for all tasks and provides comments for better understanding. This work is suitable for an in-depth study of the field of machine elements. It particularly offers support to students of mechanical engineering and related subjects. Furthermore, it can also be a valuable resource for practitioners in the fields of development, design, and testing. I hope that some points will motivate you to engage more closely with this work.
