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.
