When a force is applied, stiffness, which is defined as the resistance of an elastic body to deflection or deformation, can be represented as
k = F /[tex]$\delta$[/tex] (1), where k = stiffness (N/m, lb/in).
Where F is the load and is the bending deflection, it has a stiffness of
S = F/[tex]$\delta$[/tex]. When a force, F, is applied to an item, its stiffness, k, is calculated as the product of the force's magnitude and the object's deformation,. The slope of the elastic portion of the stress-strain curve for a particular material is taken into consideration when calculating it by dividing the longitudinal stress by the strain. A material's stiffness is primarily categorized by its modulus of elasticity.
A material's stiffness can be summed up by its Young's modulus, also known as elastic modulus. To put it another way, it is how easy it can be bent or stretched. To be more precise, the mathematics and physical values are calculated as follows: Young's modulus equals stress minus strain.
