Question

Which is more elastic glass or steel?

Answer 1

Hint: Elasticity is a measure of a variable's sensitivity to a change in another variable; in most cases, this sensitivity is the price change in relation to other factors. It's mostly used to figure out how much a change in a product's or service's pricing affects customer demand.

Complete answer:
Young's modulus is a term used to describe the ability of a The Young modulus, also known as the modulus of elasticity in tension, is a mechanical characteristic that quantifies a solid material's tensile stiffness. It is calculated using the formula: It quantifies the connection between tensile stress $\sigma $(force per unit area) and axial strain$\varepsilon $(proportional deformation) in the linear elastic region of a material.
\[E = \dfrac{\sigma }{\varepsilon }\]
Rubber is less elastic than steel. Young's modulus is used to explain this. The connection between stress (force per unit area) and strain (proportional deformation of an object) is defined by Young's modulus. When a certain load is applied to a solid object, it deforms. When the pressure is released from an elastic item, the body returns to its previous shape. Beyond a modest degree of distortion, many materials are not linear and elastic.
When a little load is given to a solid material in compression or extension, it will deform elastically. The deformation of elastic materials can be reversed.
The stress–strain curve is linear at near-zero stress and strain, and the connection between stress and strain is defined by Hooke's law, which asserts that stress is proportional to strain. Young's modulus is the proportionality coefficient. The greater the modulus, the more stress is required to produce the same amount of strain; in an idealised rigid body, the Young's modulus would be infinite. A highly soft substance, such as a fluid, on the other hand, would deform without force and have zero Young's modulus.
 STEEL is the most elastic. Steel has the steepest linear stress-strain curve of any material. The elastic modulus of a stiffer material is greater.

Note: The change in size of a bar composed of an isotropic elastic material under tensile or compressive stresses may be calculated using Young's modulus. For example, it can estimate how much a material sample would stretch or shorten under stress or compression. Young's modulus is immediately applicable to situations of uniaxial stress, which is defined as tensile or compressive stress in one direction with no stress in the other. Young's modulus is also used to estimate the deflection that will occur when a load is put between the beam's supports in a statically determinate beam.
