PREFACE In the preperation of this book the author has had in mind the fact that the student finds much difficulty in seeing the applications of theory to practical problems. For this reason each new principle developed is followed by a number of applications. In many cases these are illustrated, and they all deal with matters that directly concern the engineer. It is believed that problems in mechanics should be practical engineering work. The author has endeavored to follow out this idea in writing the present volume. Accordingly, the title Applied Mechanics for Engineers has been given to the book. The book is intended as a text-book for engineering students of the Junior year. The subject-matter is such as is usually covered by the work of one semester. In some chapters more material is presented than can be used in this time. With this idea in mind, the articles in these chapters have been arranged so that those eomirlg last may be omitted without affecting the continuity of the work. The book contains more problems than can usually be given in any one semester. While it is difficult to present new material in the matter of principles, much that is new has been introduced in the applications of these principles. The subject of Couples is treated by representing the couples by means of vectors. The author claims that the chapters on Rlonlent of Inertia, Center of Gravity, Work and Energy, Friction and Impact are more complete in theory and applications than those of ally othez - American text-book on the same subject. These are matters upon which the engineer frequently needs information frequent reference is, therefore, given to original sources of information. It is hoped that these chapters will be especially helpful to engineers as well as to students in college, and that they will receive much benefit as a result of looking lip the references cited. In general, the answers to the problems have been omitted for the reason that students who are prepared to us
