Answer 2

Answer :

Shearing Modulus :

• It is the ratio of shearing stress to shearing strain.
• It is represented by G.
• It is also called Modulus of rigidity.
• SI unit is Nm^{-2} or Pa.
• For most materials G approximately equal to Y/3.
• The shear modulus is less than Young's modulus.

G = shearing stress/shearing strain

G = (F/A)/(∆x/L)

G = (F × L)(A × ∆x)

G = (F/A)/∅

G = F/(A/∅)

The other two types of modulus include :

• Young's modulus
• Bulk modulus

Young's modulus is the ratio of tensile or compressive stress to the tensile or compressive strain.

Bulk modulus is the ratio of hydraulic stress to volume strain.
