where (x ) is determined for specific diameters of all four pulleys and for a particular distance between pulleys (3) and (4).
This completes the chapter on machine motion and thus we come to “The End” of the ten chapters of this first edition of Marks’ Calculations for Machine Design. It has been a pleasure uncovering the mystery of the formulas in machine design that are so important to bring about a safe and operationally sound design. Having said so, it must also be mentioned that for you it is just the beginning of a creative odyssey. The machines you would design based on the knowledge gained from this book, and the new ideas, theories, equations, and techniques you would come up with would go to increase the volume of books like this considerably in each subsequent edition. Best wishes for your designs.
