A rigid body does not deform under applied stress.
The CBSE syllabus for 2024-2025 includes Chapter 8 “Mechanical Properties of Solids” from the Class 11 NCERT Physics textbook. This chapter explores key concepts like stress, strain, elasticity, Young’s modulus, bulk modulus, shear modulus and Poisson’s ratio. It describes the behavior of solids under various forces and the factors influencing their mechanical properties. Multiple-choice questions help evaluate understanding of fundamental principles such as Hooke’s Law and stress-strain relations. Mastery of these concepts is essential not only for academic success but also for practical applications in fields such as engineering and material science.
