Quizplus · Accepted Answer

The relationship between stress and strain is linear, and stress is directly proportional to strain, which means stress (σ) equals a constant (E, Young's modulus) multiplied by strain (ε), or σ = Eε. This is commonly known as Hooke's Law. Therefore, the correct choice is A.
