What does the area under the stress-strain curve represent?

The area under the stress-strain curve provides insight into the mechanical behavior of the material.

The CBSE syllabus for 2024-2025 includes Chapter 8 “Mechanical Properties of Solids” from the Class 11 NCERT Physics textbook. This chapter introduces key concepts such as stress, strain, elasticity, Young’s modulus, bulk modulus, shear modulus and Poisson’s ratio. It explains how solids respond to different forces and the factors that affect their mechanical properties. Multiple-choice questions are used to test the understanding of these principles like Hooke’s Law and the stress-strain relationship. These concepts are essential for academic learning and practical applications in fields like engineering and material science.
