He paused. The number was high—too high for mild steel.

For the first time, Arjun smiled at the book. Khurmi wasn’t just giving formulas—he was teaching engineering judgment. The book was a silent mentor, unforgiving but fair. It never let you guess. It made you derive, verify, and then doubt yourself until you understood.

Step by step, he followed Khurmi’s method. First, find the reaction. Then the shear force diagram. Then the maximum bending moment at the fixed end. He calculated the moment of inertia for a square section. Then the section modulus. Then stress. R S Khurmi Strength Of Materials

He needed a thicker section. Or a fillet at the support. Or both.

“Thank you, sir,” he whispered.

Arjun had always hated this book. It was too thick, too dry, and the problems were sadistically progressive—just when you understood simple tension, it hit you with compound stress and principal planes . But tonight, desperation forced respect.

He redrew his beam. He listed the given data: Length 2 m, load 500 N at free end, cross-section 50x50 mm. He turned to the section on Cantilevers . There it was: Bending stress = (M * y) / I . He paused

“Come on, Khurmi saab,” Arjun whispered, flipping to Chapter 6: Shear Force and Bending Moment Diagrams .
