This component of the teaching and learning system 'Roloff/Matek', Machine Elements, enables educators to better prepare and conduct their courses. It provides each instructor with 126 enlarged original images from the book as templates for slides, worksheets, etc. Additionally, 5 large project tasks with extensive assignments are included, demonstrating the application of the calculation fundamentals. These comprehensive project tasks are particularly suitable for semester or group projects, even in modified forms. Alongside these two elements, we provide a diskette for the teacher that contains calculations for the 14 programs. These calculations are based on spreadsheet software, allowing for quick changes to parameters and verification of the effects on the component.
