For maximum extension with given load for a wire with same value of young's modulus of elasticity, which is true?

Answer»

Is it true that a material with a higher Young's MODULUS is more elastic than a material with a lower Young's modulus? If so, why?

Young’s modulus, or the modulus of elasticity, is the measure of stiffness of a material. It is a mechanical PROPERTY measured in pressure of the relationship of the stress (force per unit area) and strain (resulting proportional deformation) of a material. Many materials with a high Young’s modulus will bend under stress but may return to their original shape when the force is removed because Young’s modulus is a measure of linear elasticity. Do not confuse the strength of a material to Young’s modulus. Lead has a very low modulus of elasticity. It requires LITTLE stress to cause permanent deformation and it will not return to its original shape. A rubber band likewise has a low modulus of elasticity, deforms significantly under load but returns to it’s original shape. Young’s modulus is simply a MEANS of describing with numbers our perception of the stress/strain relationship
