In a Hooke's law experiment a the length of the spring was 32cm when 4N was added, 33cm when 6N was added, 34cm when 8N was added and 36cm when 12N was added. What would be the extension when 15N is added?

Answer:
relationship is given by σ = E* ε, where σ represents stress, ε represents strain and E represents Young's modulus of elasticity. Using this means of inferring stress, strain is a geometrical measure of deformation and Young's modulus is a measure used to characterize the stiffness of an elastic material.
