An attempt is made in this book to present a logical development of mechanics starting from its basic principles and it may be regarded as a companion volume to the standard texts by well-known authors. While the material on rigid bodies and analytical mechanics can be taught at the post graduate level, selected topics from the earlier chapters serve as instructional material even at lower levels. Another feature of the book is the unusually large number of worked examples to enable the student to gain a deeper insight into the basic principles of mechanics.
