Which of the following materials shows elastic behavior over a large range of stress?

Materials with high elasticity can sustain large deformations without permanent change.

The CBSE syllabus for 2024-2025 includes Chapter 8 “Mechanical Properties of Solids” from the Class 11 NCERT Physics textbook. This chapter focuses on crucial concepts like stress, strain, elasticity, Young’s modulus, bulk modulus, shear modulus and Poisson’s ratio. It provides an in-depth understanding of how solids behave under various types of forces and the factors that affect their mechanical properties. The chapter explains how materials deform and how their strength and flexibility are determined. Multiple-choice questions are included to test the understanding of key principles such as Hooke’s Law and stress-strain curves. These questions are designed to assess how well students grasp the application of these concepts in real-life scenarios such as engineering and materials science. A thorough understanding of these principles is important not only for academic success but also for practical applications in designing structures and selecting materials in engineering fields.
