Mechanical Properties of Solids in One Shot | Class 11 Physics ISC | Stress, Strain, Young’s Modulus

Описание: Welcome to Chapter 7 – Mechanical Properties of Solids from Class 11 Physics (ISC Board).
In this video, we’ll break down one of the most important chapters — how solids behave under external forces.

Here’s what you’ll learn:
📘 Stress and Strain — the foundation of elasticity
⚙️ Hooke’s Law and Elastic Limit
📊 Young’s Modulus, Bulk Modulus, and Shear Modulus
🧩 Stress-Strain Graph and Elastic Behavior
🏗️ Real-life examples — bridges, springs, and materials in construction
