Question

Area under force - elongation graph gives
(A) Stress
(B) Strain
(C) Strain energy
(D) Young's modulus​

Answer 1

Answer:

strain energy is the correct answer

Answer 2

Explanation:

The area under this graph of force vs. extension is in Joules, units of energy. This is because the area is in units of Newtons (vertically) times meters (horizontally). Do not forget that units of work are units of force times units of displacement, or units of Newtons times units of meters.
