NCERT Exercise 8.2 | Stress-Strain Curve | Young’s Modulus & Yield Strength | Class 11 Physics

NCERT Exercise Question 8.2, Chapter 8 – Mechanical Properties of Solids for Class 11 Physics.

QUESTION:
The figure shows the strain–stress curve for a given material. What are (a) Young’s modulus and (b) approximate yield strength for this material?

This session focuses on understanding the stress–strain curve, identifying the linear elastic region, calculating Young’s modulus from the slope of the graph, and determining the yield strength from the curve so that students can confidently answer graphical questions in exams.
