Which feature of the following graph represents Young's Modulus?
Correct answer: C. Reciprocal of the gradient
- A. Area under graph
- B. Gradient of the graph
- C. Reciprocal of the gradient
- D. Product of gradient and area of the curve
Explanation
Young's modulus of elasticity (E), also known as the elastic modulus, is the ratio between stress and strain. Since the gradient of graph is strain/stress (gradient = x-axis/y-axis). So, its reciprocal would be equal to Young's modulus.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
