How to find the modulus of elasticity in a material?

To find the modulus of elasticity in a material, you can conduct a test called a tensile test. This test involves applying a controlled amount of force to a sample of the material and measuring how much it deforms. The modulus of elasticity is then calculated by dividing the stress (force applied) by the strain (deformation). This value represents the material's ability to deform under stress and return to its original shape.
