NCERT Solutions for Class 11 Physics Chapter 9

This chapter is very useful for college-level Physics. Furthermore, the chapter has wide applications in chemistry as well. Properties of Solids are important to engineers as well. Also, astronomers need to properly understand the properties of solids. In the constructions of roads and railways, this information is important. Geologists will also find this chapter’s information vital. This is because properties of solids change with change in weather conditions.
Below are the sub-units of chapter 9:

9.1 Introduction –

This part introduces the student to this chapter. The student certainly gets a basic idea about the properties of solids.

9.2 Elastic behaviour of solids –

Elasticity refers to the ability of a solid to resume its normal shape. Above all, the solid resumes its shape after being stretched or compressed.

9.3 Stress and strain –

Stress refers to a reforming force. Furthermore, this force develops in a body. The force develops when the body is subjected to a deforming force. A strain refers to a measure of deformation. Also, strain shows the displacement between particles in the body. This displacement is relative to a reference length.

9.4 Hooke’s Law –

Here stress and strain are proportional to each other. This happens when deformations are small.

9.5 Stress strain curve –

There certainly exists a relationship between stress and strain. Furthermore, this relationship is for a given material under tensile stress. Most noteworthy, there is a discussion of this relationship in this sub-unit.

9.6 Elastic moduli –

Modulus of elasticity is the ratio of stress and strain. Also, this sub-unit also has Young’s Modulus. Furthermore, there is also Shear Modulus and Bulk Modulus here.

9.7 Applications of elastic behaviour of materials –

Elastic behaviour of materials has several applications. These applications are discussed here.
