Mechanisms and Dynamics of Machinery

This book offers excellent development of kinematics, largely using the polar(complex number) method where an individual joint or pin is an origin and the end of its attached rod is given coordinates relative to this origin. Rod positions for other rods on the chain are then found by vector or coordinate addition when position is needed from another origin. In this way once certain pins are chosen to be fixed and a (driver)rod is given an angular position relative to its fixed origin, all other positions of joints and rods are determined, hence velocities and accelerations, linear and angular , too. All this involves little more sophistication than the law of cosines from high school trigonometry. Graphical means are also given but largely as a check on coordinate methods. In this age of the pc, coordinate methods are preferred.Once accelerations are found, the inverse or dynamics problem is explored. Accelerations having been determined by kinematics, forces or reactions on joints are found. The center of mass of any rod in the chain accelerates due to the reaction forces at its joints. A similar though more involved statement applies to torques. Ultimately a system of these linear equations is found where reactions are then determined by Cramer's rule. Unfortunately this procedure may have to be repeated for each position-not a problem in the computer age.This gives the gist of a significant portion of the book. As other reviewers have remarked, it is clear and easy to follow. Only thing I didn't like was occasionally a formula was given with a reference instead of a derivation. In particular, the universal joint annoyed me but it involves spherical trigonometry and I found it in Shigley's Kinematic Analysis. Still you're given the background to understand Shigley. Highly recommended for any mechanical engineering student or mechanical engineer.

It's a very good book, I used in my grad school and that how I learnt most of the mechanics of gears.

Very complete book. I recommend it, specially as a textbook for schools. I bougt it from Anybook which sent it to my in a very way.

The product arrived more quickly than expected, and in excellent condition. I would highly recommend this seller. The book came in a condition that was better than described.

Great condition

Just what I needed for school. I used it and did well in the class so i guess it did the job.

It's one of the most beautiful books of mechanisms I have ever read!

The programming taught in this book doesn't exist anymore.Book is inconsistent in verbage and jumps around, assuming you know concepts before they're presented.

To be honest, I was expecting worse but the condition of the book was really good .

Good like new!

Love this one!! the paper is so good!!!!
