Question

explain all the three modulus of elasticity ??? ☺☺

Answer 1

elastic moduli

1.Young's modulus (E) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis.

It is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the elastic modulus.

2.The shear modulus or modulus of rigidity (G or μ ) describes an object's tendency to shear (the deformation of shape at constant volume) when acted upon by opposing forces.

It is defined as shear stress over shear strain. The shear modulus is part of the derivation of viscosity.

3.The bulk modulus (K) describes volumetric elasticity, or the tendency of an object to deform in all directions when uniformly loaded in all directions.

It is defined as volumetric stress over volumetric strain, and is the inverse of compressibility

FIND MODULUS

Young's Modulus (E) or the modulus of elasticity is a measure of a materials stiffness. The higher the Young's modulus value the stiffer the material. Young's modulus can be calculated from tensile test stress/strain graphs–derived from load/extension graphs.

Young's modulus = stress/strain = (FL0)/A(Ln − L0). This is a specific form of Hooke's law of elasticity. The units of Young's modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m2)
