Statics and Dynamics textbook for ENGR 141 and MECH 242. In very good, clean condition. Includes both study packs with unused access codes for the companion website. I bought this package new at the bookstore for over $200. They were my companions throughout the nightmares of 141 and 242, but it is time for them to move on. Compared to other copies, there are very few tear stains on these pages. (jk ;) Can deliver or meet on campus. Email, text, or call anytime! Best offers considered.
