Machines By Rs Khurmi Exercise Solutions - Theory Of
Problem: A Porter governor has equal arms of length 250 mm. Upper arms pivoted on axis, lower arms attached to sleeve. Mass of each ball = 5 kg, central load = 30 kg. Find equilibrium speed when radius of rotation = 150 mm.
Solution:
Using formula for Porter governor:
( N^2 = \frac(m+M)m × \frac895h )
where h = √(l² – r²) = √(0.25² – 0.15²) = 0.2 m
( N^2 = (5+30)/5 × 895/0.2 = 7 × 4475 = 31325 )
N = 177 rpm

Navigating Theory of Machines by R.S. Khurmi: A Guide to Exercise Solutions
Theory of Machines by R.S. Khurmi and J.K. Gupta is the "bible" for many undergraduate mechanical engineering students. While the text provides clear explanations, the end-of-chapter exercises are designed to test your ability to apply abstract concepts to real-world mechanisms. Mastering these solutions requires a blend of graphical precision and algebraic accuracy. 1. The Core Focus Areas
The exercises in Khurmi generally fall into three categories:
Kinematics: Solving for displacement, velocity, and acceleration using both analytical methods and the Relative Velocity/Instantaneous Centre methods.
Dynamics: Analyzing forces in mechanisms, including turning moment diagrams and flywheel design.
Specialized Mechanisms: Focused problems on gears, gear trains, cams, and governors. 2. Strategy for Graphical Solutions
Many problems, especially in chapters like Velocity in Mechanisms or Cams, require graphical construction. Problem: A Porter governor has equal arms of length 250 mm
Scale Matters: Khurmi’s solutions often depend on a well-chosen scale (e.g.,
). Small errors in drawing lead to large discrepancies in the final answer. Vector Notation: Use the
notation consistently. The exercises are designed to reinforce the "vector loop" mentality. 3. Analytical and Numerical Mastery
For chapters like Gears or Vibrations, the solutions are purely mathematical.
Standard Formulae: Khurmi relies heavily on standard derivations. For instance, in Gear Trains, the tabular method for epicyclic gears is the most reliable way to reach the textbook's solution.
Unit Consistency: A common pitfall in these exercises is mixing (rpm) with
(rad/s). Always convert to SI units before plugging values into the energy or force equations. 4. How to Use Solutions Effectively
The goal of working through Khurmi’s exercises isn't just to match the number at the back of the book, but to understand the Degrees of Freedom and the constraint motion of the links.
Self-Testing: Attempt the problem using the provided "Hints" first. Khurmi often provides the final answer in brackets; use this as a milestone, not a crutch.
Reverse Engineering: If your answer differs, check your Free Body Diagrams (FBD). Most errors in the "Dynamics of Machinery" section stem from incorrect force directions. Conclusion
Solving the exercises in R.S. Khurmi’s Theory of Machines is a rite of passage for engineers. It builds the foundational intuition needed to design everything from simple linkages to complex automotive transmissions. Success lies in patience with drawing instruments and rigor in algebraic substitution.
