This set includes two books. The first, 'A Treatise on Dynamic of a Particle', is authored by Edward John Routh and published by Dover Publications in 1960. The edition is unstated. The second, 'Dynamics of a System of Rigid Bodies', is also by Routh, published by Dover in 1960, and is the 7th Revised & Enlarged Edition. The books are in acceptable condition. The binding of 'A Particle' is a bit loose in places, but no pages are missing. There's soiling and staining on the bottom text block of both books, creasing at the hinges of the covers, and moderate soiling on the covers. Some pages in 'A Particle' near the side with paint splotches are stuck together, yet the books remain readable. The pages throughout are clean and bright.
These books are great resources for learning about particle and rigid - body dynamics. To use them, simply open to the relevant chapter and start reading. When handling the books, be gentle, especially with 'A Treatise on Dynamic of a Particle' as its binding is a bit loose. Avoid placing them in a dirty or wet environment to prevent further soiling. If you want to clean the covers gently, you can use a soft, dry cloth. When not in use, store them in an upright position on a bookshelf to maintain their shape. And always remember to handle them carefully to ensure they last for a long time.
