Step 1: Understand the terms. Shear modulus (G) is a measure of how much a material deforms under shear stress. Shear stress (τ) is the force applied per unit area.
Step 2: Convert the units if necessary. Here, shear stress is given in MPa (megapascals) and shear modulus in GPa (gigapascals). 1 GPa = 1000 MPa.
Step 3: Write down the formula for shear strain (γ): γ = τ / G.
Step 4: Substitute the values into the formula. τ = 40 MPa and G = 80 GPa = 80,000 MPa.
