The ration stress to strain in youngs modulus of the material then tension is__________________?
Correct answer: A. Directly proportional to extension
- A. Directly proportional to extension
- B. Directly proportional to strain
- C. Directly proportional to square of amplitude
- D. Inversely proportional to extension
Explanation
Within the elastic limit, Young's modulus remains constant, so stress is proportional to strain. Since tension produces the extension in this range, the extension is directly proportional to the applied tension or force. Inversely proportional to extension, the likely mistaken choice, would contradict Hooke's law.

About Work-Energy Theorem
The work-energy theorem states that the net work done on an object equals its change in kinetic energy. Questions involve positive and negative work, variable forces and force-displacement graphs, acceleration or deceleration, and the difference between this theorem and conservation of mechanical energy, which also requires attention to potential energy and non-conservative work.
