Stress, strain, and Young's modulus are all factors linked to the performance of a material or object in a particular setting.

Stress: Simple engineering stress is similar to pressure in that it is calculated as force per unit area. Stress is a physical quantity closely associated with 'internal force.' It measures the average amount of force exerted per unit area over a material. The maximum amount of stress a material can withstand before breaking is called breaking stress or ultimate tensile stress.

Strain: Strain is the response of a system to an applied stress. When a material is loaded with a force, it produces stress, which causes the material to deform. Engineering strain is defined as the amount of deformation in the direction of the applied force divided by the initial length of the material.

Formula :
ε =  (L₂ - L₁)/L₁
σ = F/A
E = σ/ε

Where,
F =  Force
A = Area
L₁ =  Initial Length
L₂  = Final Length
ε = Strain 
σ = Stress 
E = Young's modulus
