Answer:
Step-by-step explanation:
Poisson's ration= is the ratio between the deformation that occurs in the material in the direction perpendicular to the force applied with the deformation suffered by the material in the same direction of the force.
young's modulus= is the ratio between the stress applied to a material with respect to its unit deformation when this material complies with the hooke's law.
shear modulus=change in the way an elastic material experiences when subjected to shear stresses
