Dilatometer is used to measure __________________?
Correct answer: B. Contraction/expansion due to changes in temperature
- A. Stress
- B. Contraction/expansion due to changes in temperature
- C. Deflection
- D. Strain
Explanation
A dilatometer measures dimensional change, especially expansion or contraction, as temperature changes. Stress and strain require mechanical testing instruments rather than a dilatometer.
