Stress is a measure of the internal force developed in a material when subjected to an external force. It is expressed as force per unit area.
The CBSE curriculum for the 2024-2025 academic year includes Chapter 8, “Mechanical Properties of Solids,” from the Class 11 NCERT Physics textbook. To enhance conceptual understanding, multiple-choice questions (MCQs) are an essential practice tool. These questions focus on key topics such as stress, strain, elasticity, Young’s modulus, bulk modulus, shear modulus and Poisson’s ratio. Rephrased MCQs are designed to assess comprehension of principles like Hooke’s Law, stress-strain curves and factors affecting material deformation. This chapter emphasizes real-world applications, enabling students to grasp the mechanical behavior of solids under force, essential for both theoretical knowledge and practical applications in physics.
