The image above represents shear modulus.

To compute for shear modulus, two essential parameters are needed and these parameters are **Shear Stress (τ) **and **Shear Strain (γ).**

The formula for calculating shear modulus:

G = ^{τ}/_{γ}

Where:

G = Shear Modulus

τ = Shear Stress

γ = Shear Strain

Given an example;

Find the shear modulus when the shear stress is 15 and the shear strain is 3.

This implies that;

τ = Shear Stress = 15

γ = Shear Strain = 3

G = ^{τ}/_{γ}

G = ^{15}/_{3}

G = 5

Therefore, the **shear modulus **is **5 Pa.**

**Calculating the Shear Stress when the Shear Modulus and the Shear Strain is Given.**

τ = G x γ

Where:

τ = Shear Stress

G = Shear Modulus

γ = Shear Strain

Let’s solve an example;

Find the shear stress when the shear modulus is 20 and the shear strain is 4.

This implies that;

G = Shear Modulus = 20

γ = Shear Strain = 4

τ = G x γ

τ = 20 x 4

τ = 80

Therefore, the **shear stress **is **80 Pa.**
