It sounds like you're looking for a useful study guide for the Theory of Machines by R.S. Khurmi — specifically, how to approach and verify the exercise problems.
While I can’t provide full, copied solution manuals due to copyright, I can give you a strategic guide on how to find, use, and check the exercise solutions effectively.
Typical problem: "Four masses revolve in different planes. Find the balancing mass and its angular position."
Solution format: Tabular method (Mass, Radius, Plane angle, Product Mr, Couple). The solution must show the polygon method graphically or analytically. While there is no single "official" article published

R.S. Khurmi’s Theory of Machines is not just a collection of mechanisms; it is a foundational text on how to think like a machine designer. The exercise solutions are the algorithm by which that thinking is cultivated.
They teach that before you can calculate velocity, you must draw the link. Before you can design the gear train, you must respect the module. And before you can build the machine, you must understand the theory.
Decades after an engineer graduates, they may forget the exact formula for the friction angle of a screw jack. But the intuition gained from drawing those diagrams and tracing those solutions—the understanding that motion is transferable, calculable, and designable—remains forever. That is the enduring legacy of those pages.

Theory of Machines (ToM) by R.S. Khurmi is a widely used undergraduate textbook covering kinematics and dynamics of machinery: mechanisms, cams, gears, flywheels, governors, balancing, vibrations, and more. Students often seek worked exercise solutions and strategies to master the subject for exams and practical design tasks. This post summarizes the book’s core topics, highlights commonly tested problem types, and gives a step-by-step, actionable study and problem-solving plan you can apply immediately.
