The stress due to suddenly applied load is either a or b of the gradually applied load.

Answer:

b.2 times

Explanation:

Work done is equal to the strain energy stored.

(F δL) / 2 = (σ2 / 2E) AL

Therefore, σ = (F/A) ----------- (1)

- Suddenly applied load is given as σ = (2F/A), here work done = (F δL)

(F δL) = (σ2 / 2E) AL

Therefore, σ = (2F/A) ------------- (2)

From (1) and (2), it can be concluded that

Hence, suddenly applied load is twice the gradually applied load.
