R S Khurmi Strength Of Materials May 2026

Arjun had a problem. His end-semester design project was a simple steel cantilever beam meant to support a small hoist. But his calculations kept showing failure. Every time he computed the bending moment, his answer was off by a factor of ten. His roommate, Rohan, had already submitted his project and was snoring peacefully.

By 2 AM, Arjun had redesigned the beam with a 10 mm fillet and a 60x60 mm section. He recalculated deflection (Chapter 9) and checked buckling (Chapter 18). Everything passed. R S Khurmi Strength Of Materials

But Arjun now knew it was for something more—for anyone who wanted to build things that wouldn’t break. He patted the book gently. Arjun had a problem

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. Every time he computed the bending moment, his
