→ Young’s modulus describes the relationship between stress (force per unit area) and strain (proportional deformation in an object.
→ The Young’s modulus is named after the British scientist Thomas Young. A solid object deforms when a particular load is applied to it.b

The mechanical property of a material to withstand the compression or the elongation with respect to its length.
It is denoted as E or Y.
Notations Used In The Young’s Modulus Formula
E is Young’s modulus in Pa
is the uniaxial stress in Pa
ε is the strain or proportional deformation
F is the force exerted by the object under tension
A is the actual cross-sectional area
ΔL is the change in the length
L0 is the actual length
