PROPERTIES OF SOLIDS AND LIQUIDSSOLID & ELASTICITY
Stress, Strain and Elastic Moduli
Stress : Restoring force developed/Area.
Strain : Change in dimension/original dimension.
Stress
Modulus of Elasticity = Strain
Greater is modulus of elasticity greater is the stress
developed i.e., greater is the restoring force.
Young’s Modulus
Young’s modulus is a measure of the resistance of a solid
to a change in its length when a force is applied
perpendicular to a face.

, Young’s modulus Y for the material of the rod is defined
as the ratio of tensile stress to tensile strain.

Shear Modulus
The shear stress is defined as
Tangetial force
Shear Stress =

Where A is the area of the surface.

, Density and Pressure
The density of a substance is defined as the mass per unit
volume of a sample of the substance.
M
=
V
The SI units of density are kg m-3.
Specific Gravity
The specific gravity of a substance is the ratio of its
density to that of water at 4oC, which is 1000 kg/m3.
Specific gravity is a dimensionless quantity numerically
equal to the density quoted in g/cm3. For example, the
specific gravity of mercury is 13.6, and the specific gravity
of water at 100oC is 0.998.
