By understanding the modulus of elasticity of steel, we can claim that steel is more rigid in nature than wood or polystyrene, as its tendency to experience deformation under applied load is less.Youngs modulus is also used to determine how much a material will deform under a certain applied load. Modulus of Rupture Wood. Youngs Modulus Factors. In materials science and solid mechanics, Poisson's ratio is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading.The value of Poisson's ratio is the negative of the ratio of transverse strain to axial strain.For small values of these changes, is the amount of transversal elongation divided Draw the piece of wood along the surface at a constant velocity and record the reading on the spring scale.
