On this page, you will find a link to Professor Samuel Doughty's book called Mechanics of Machines. The first edition of this book was published in 1988. The second edition of this book is published in pdf format and is offered freely to all people interested in the subject. The book is heavily dependent on computer simulations and calculations. Having said that, this new edition might contain some errors and with your help, each version will be better than the previous version. Your contribution to this book will further enhance its value for the next generation of the engineering students.
I benefited from this book greatly and I am hoping that you will find it as useful as I did.
You can download the pdf version for the new edition of the book from the following link.
For those who may want the full volume, printed and bound in a soft cover, it is available at minimal cost HERE:
