FAQs on DC Pandey Solutions (JEE Main): Elasticity - DC Pandey Solutions for JEE Physics
| 1. What is elasticity in the context of JEE Main Physics? |  |
Ans. In the context of JEE Main Physics, elasticity refers to the property of a material to regain its original shape and size after being deformed by an external force. It is a measure of how much a material can stretch or compress under the influence of a force.
| 2. How is elasticity related to the JEE Main exam? | |
Ans. Elasticity is an important topic in the JEE Main Physics syllabus. Questions related to elasticity often appear in the exam, testing the understanding of concepts such as stress, strain, Young's modulus, and Hooke's law. It is essential for JEE Main aspirants to have a clear understanding of elasticity to solve these questions accurately.
| 3. What is Young's modulus? | |
Ans. Young's modulus, denoted by the symbol 'Y', is a measure of the stiffness or rigidity of a material. It is defined as the ratio of stress (force per unit area) to strain (deformation per unit length) in a material within the elastic limit. Young's modulus is a fundamental concept in elasticity and is used to determine the extent of deformation a material undergoes under the application of a force.
| 4. How can I calculate the strain in a material? | |
Ans. Strain is calculated by dividing the change in length of a material by its original length. Mathematically, strain (ε) is given by the formula: ε = (ΔL / L), where ΔL represents the change in length and L represents the original length of the material. Strain is a dimensionless quantity and is often expressed as a decimal or a percentage.
| 5. What is Hooke's law? | |
Ans. Hooke's law states that the extension produced in a material is directly proportional to the applied force, provided the elastic limit of the material is not exceeded. Mathematically, Hooke's law can be represented as F = kx, where F is the applied force, k is the spring constant (a measure of the stiffness of the material), and x is the extension or compression of the material. Hooke's law is applicable to materials within their elastic limit, and it helps in understanding the behavior of materials under the influence of external forces.
