Overall: ★★½ (2.5/5) – A necessary evil for mechanical engineering students in India. Use Khurmi’s exercise solutions only as an answer key, not as a learning resource. For real understanding, pair with S.S. Rattan’s solved examples or online NPTEL videos. If possible, form a study group to cross-check solutions, especially for velocity/acceleration and gyroscope problems.
For over four decades, "Theory of Machines" by R.S. Khurmi has been the bedrock textbook for mechanical engineering students in India and beyond. Whether you are preparing for the GATE exam, semester-end university tests, or competitive exams like IES and SSC JE, this book is likely on your mandatory reading list.
However, owning the textbook is only half the battle. The true test of knowledge lies in solving the numerical problems at the end of each chapter. This is where Theory of Machines by RS Khurmi exercise solutions become the student’s most vital resource.
In this comprehensive guide, we will explore why these solutions are critical, where to find accurate step-by-step answers, and how to use them effectively to ace your exams.

R.S. Khurmi’s Theory of Machines is a standard textbook for mechanical engineering students worldwide. While the theory is well-explained, the exercise problems are crucial for cracking competitive exams like GATE, ESE, and university semester exams.
Here is how you can access and effectively utilize these solutions. While there is no single "official" article published
To illustrate quality, let’s take a typical problem from Chapter 10 (Toothed Gearing):
Problem: Two mating gears have 20 and 40 teeth. Module = 5 mm. Pressure angle = 20°. Find the center distance and the radii of base circles.
Good solution would show:
Bad solution would only write final numbers without formulas or unit conversions.
Perhaps the most intellectually satisfying solutions in the book are found in the chapter on Gyroscopes. Gyroscopic couple and precession are concepts that often defy intuition. The vector algebra can be confusing, with rules about "spin," "precession," and "active force" planes.
Khurmi’s solutions to gyroscopic problems—ranging from naval ship stabilization to aircraft turning—are masterclasses in vector logic. They consistently apply the right-hand screw rule in a repetitive, reinforcing manner.
By following the solution for a naval ship problem, the student isn't just solving for a scalar value; they are learning how to define a coordinate system. The solutions teach that in dynamics, direction is just as vital as magnitude. It is a lesson in discipline: misplace one arrow, and the ship capsizes.
Problem: Two involute gears have module = 5 mm, pressure angle = 20°, number of teeth on pinion = 20, gear = 40. Find addendum, dedendum, pitch circle radii, and path of contact.
