In this chapter, we will learn about the Mechanical Properties of Solids. Subject- Physics chapter- Mechanical Properties of Solids Read full ncert pdf online with notes & video guides J is a conversion factor (not a physical quantity) and its value is 4.186 J/cal. • Elasticity The property of the body […] MECHANICAL PROPERTIES OF SOLIDS 237 As a result of applied tangential force, there is a relative displacement ∆x between opposite faces of the cylinder as shown in the Fig. It is referred to as the Elastic Behavior Of Solids. This includes finite elastic behavior, linearviscoelasticity and mechanical relaxations, mechanical anisotropy,non-linear viscoelasicity, yield behavior and fracture. But say, you take an aluminium rod and try to bend it using your arm strength. These forces are known as inter molecular forces. Mechanical energy or work (W) can be converted into heat (Q) by 1 W = JQ where J = Joule’s mechanical equivalent of heat. Elasticity and Plasticity View 6.

Of course not. You somehow do manage to bend it a little and then stop applying force. A solid material has a definite shape and size. In order to change the shape and size of the solid object, an external force needs to be applied. Providing an updated and comprehensive account of the propertiesof solid polymers, the book covers all aspects of mechanicalbehaviour. Mechanical Properties of Solids Class 11 Notes Physics Chapter 9 • Inter molecular Force In a solid, atoms and molecules are arranged in such a way that each molecule is acted upon by the forces due to the neighbouring molecules. Engineers use the concepts and methods of mechanics of solids in designing and evaluating tools, machines, and structures, ranging from wrenches to cars to spacecraft.
