Students can easily download the PDF Class 11 Chapter 9 Physics. You can also learn Chapter 9 of Physics online i.e. Mechanical Properties of Solids. In Introduction part of this chapter we will study aspects of Mechanical Properties of Solid substances or objects. Further in Elastic Behavior of Solids discuss when forces is applied to solids, they undergo to deformation. But, if the material or object is elastic, it allows to return at initial form, if force withdrawn. Further under this chapter of physics Class 11 Chapter 9, we will study about concept of Stress and Strain. Stress is the force applied and strain is the extension of per unit length. Afterwards, we will learn about Hooke’s Law, Hooke’s Law is a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance. The law is named after 17th century British physicist Robert Hooke. Stress – Strain Curve, states about stress and strain values of a material under differing loads that can be plotted on a graph. The Elastic Modulus is the measure of the stiffness of a material. In other words, it is a measure of how easily any material can be bend or stretch. At the end of this chapter of Physics class 11 chapter 9, we will study about Applications of elastic behaviour of materials.
