What type of stress acts perpendicular to the surface?

Stress can be classified based on the direction of the applied force. This type of stress acts normal to the cross-sectional area.

The CBSE syllabus for the 2024-2025 academic year includes Chapter 8 titled “Mechanical Properties of Solids” from the Class 11 NCERT Physics textbook. This chapter emphasizes understanding key concepts such as stress, strain, elasticity, Young’s modulus, bulk modulus, shear modulus, and Poisson’s ratio. Multiple-choice questions are an important tool for testing knowledge and improving comprehension of these concepts. Rephrased MCQs are crafted to cover fundamental principles like Hooke’s Law, stress-strain relationships, and factors influencing material deformation. The chapter also explores the behavior of solids under different types of forces and explains their mechanical responses. Students learn to apply these concepts in real-world situations and gain insights into the structural properties of materials. Practicing MCQs based on this chapter helps in better preparation for exams while fostering a deeper understanding of how solids behave under various conditions which is crucial for both academic and practical learning in physics.
