Solution
(b) Hookes law establishes the relationship between stress and strain
Stress$:$ The force per unit area
Strain$:$ The elongation or contraction per unit length (dimensionless)
The ratio of stress to strain is known as the elastic modulus of the material
Elastic Modulus $=\frac{\text {stress}}{\text {strain}}$ Hence, the modulus of elasticity is dimensionally equivalent to the stress
