I borrowed it from a nephew that acquired it during the pursuit of an ME degree. IMO it is a very good book if your linear algebra
is good. Mine indeed got left on the cutting room floor.
Book is part of the McGraw-Hill Series in Mechanical Engineering.
Used price ( university bookstore was $41). The computer stuff is pretty well dated but the theory is still there.
