What is the ratio between stress and strain?

$\huge{\underline{\boxed{\boxed{\red{\mathcal{ANSWER:}}}}}}$

• The ratio between stress and strain is known as modulus of elasticity.
• Hook's law derive the ratio between stress and strain.

$\star{\bf{\blue{\underline{Hook's\;law:}}}}$

⇒ According to Hook's law elongation produce in a wire is directly proportional to load attached to it.

⇒ Elongation ∝ load

⇒ Stress ∝ Strain

⇒ Stress = E Strain

⇒ E = Stress/Strain

⇒ Where, E = Modulus of elasticity.

$\star{\bf{\blue{\underline{Extra\;Info:}}}}$

What is Stress?

⇒ It is the ratio of deforming force acting per unit area of an object.

⇒ Stress = Force/Area

Types of Stress:

• Longitudinal stress
• Normal stress
• Tangential stress

What is Strain?

⇒ It is the ratio of change in dimension with respect to original dimension.

⇒ Strain = Change in dimension/Original dimension.

Types of Strain:

• Longitudinal strain
• Volumetric strain
• Shearing strain.

According to Hook's law elongation produce in a wire is directly proportional to load attached to it.

⇒ Elongation ∝ load

⇒ Stress ∝ Strain

⇒ Stress = E Strain

⇒ E = Stress/Strain

⇒ Where, E = Modulus of elasticity.
