Hard covered book titled AN ELEMENTARY TREATISE ON THEORETICAL MECHANICS by Alexander Ziwet, May 1903.
This vintage book is in Good condition. Pages, yellowed from age, are intact, and the binding is tight. Small amount of writing on some pages. A previous owner's name is written on the cover page, and the hinge is separating at the spine, but the pages are tight. It would make a nice addition to your math library!
