Elastic Behaviour, Stress & Strain
Match List I with List II:
Choose the correct answer from the options given below:
| LIST I | LIST II | ||
| A. | A force that restores an elastic body of unit area to its original state | I. | Bulk modulus |
| B. | Two equal and opposite forces parallel to opposite faces | II. | Young's modulus |
| C. | Forces perpendicular everywhere to the surface per unit area same everywhere | III. | Stress |
| D. | Two equal and opposite forces perpendicular to opposite faces | IV. | Shear modulus |
Show answer and solution
Answer: (b)
- A: restoring force per unit area is stress (III).
- B: equal and opposite forces parallel to opposite faces cause shear, so shear modulus (IV).
- C: equal normal force per unit area all over the surface is a volume change, so bulk modulus (I).
- D: equal and opposite forces perpendicular to opposite faces change the length, so Young's modulus (II).
- So the answer is (b) A-III, B-IV, C-I, D-II.
