Question

Which of the following is reversible?

• A. Vertical movement due to sinking of supports
• B. Movements due to shrinkage and creep
• C. Movements due to prestressing
• D. Longitudinal movement due to temperature variation

Hint:

Reversible movements usually occur due to temperature changes, whereas other types like shrinkage and creep are not reversible.

Answer 1

The Correct Option is D

Longitudinal movements due to temperature variation are reversible, meaning the structure can return to its original position as the temperature changes back. Movements caused by sinking of supports, shrinkage, or creep are generally non-reversible. Hence, the correct answer is (4) "Longitudinal movement due to temperature variation."
