MECHANICS OF SOLIDS AND FLUIDS in 1 Shot - NEET Physics

## Mechanics of Solids and Fluids Mechanics of solids and fluids covers the behavior of materials under force, including deformation, elasticity, and flow. It is a core topic for NEET, with heavy emphasis on definitions, laws, formulas, and exam-style applications. The subject is divided into solid mechanics (stress, strain, elasticity)...

A graph is plotted between load and the extension in case of a metallic wire. If it is a straight line passing through origin, then the area under the curve will give

<p style="text-align: justify;">Energy stored in the wire</p>

Which of the following statements is/are incorrect?

I. Hooke's law is applicable only within elastic limit

II. Young's modulus is dimensionless

III. Stress multiplied by strain is equal to the stored energy

II and III only

What is the general definition of stress in the context of solid mechanics?

Restoring force per unit area

Which property allows a material to regain its original configuration after the removal of deforming forces?

Elasticity
