YOUNG'S MODULUS Definition & Meaning

Young's modulus

noun

Physics.

a coefficient of elasticity of a substance, expressing the ratio between a stress that acts to change the length of a body and the fractional change in length caused by this force.

Young's modulus

noun

a modulus of elasticity, applicable to the stretching of a wire etc, equal to the ratio of the applied load per unit area of cross section to the increase in length per unit length E
