Question

Hook’s law is said to be the fundamental law in elasticity.

1. State Hook’s law of Elasticity.

2. Name the different types of modulus of elasticity with their equations​

Answer 1

Hooke's law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load.

There are many types of elastic constants, like:

Bulk modulus (K)

Young's modulus or modulus of Elasticity (E)

Poisson's Ratio (µ)

Shear modulus or modulus of rigidity (G)
