What is the relationship between shear stress and shear strain in a material?
Step 1: Understand what shear stress is. Shear stress is the force applied parallel to the surface of a material divided by the area over which the force is applied.
Step 2: Understand what shear strain is. Shear strain is the measure of how much a material deforms when shear stress is applied, expressed as the change in shape relative to its original shape.
Step 3: Learn about the shear modulus. The shear modulus is a constant that relates shear stress to shear strain in a material.
Step 4: Know the formula. The relationship can be expressed with the formula: Shear Stress = Shear Modulus × Shear Strain.
Step 5: Recognize that this means if you know the shear modulus of a material, you can predict how much it will deform (shear strain) when a certain shear stress is applied.
