Hooke’s Law modulus of elasticity

Hooke’s Law & the stress-strain formula introduces a new term called modulus of elasticity

Inside a continuous elastic material (such as a block of rubber, or a steel bar), the stresses and strains of the material are connected by a linear relationship. This relationship is mathematically similar to Hooke’s spring law and is often referred to by that name.

Hooke’s Law introduces the modulus of elasticity

From Hooke’s Law for small deformations in a continuous elastic material, the ratio of stress and strain comes out to be constant.

Stress/Strain = K (constant)

 This constant K is the ratio of stress and strain, and is termed as modulus of elasticity.

Modulus of elasticity formula

Modulus of elasticity = stress/strain
