Which one is INCORRECT?
Which one is INCORRECT?
Show Hint
Young's modulus is a property that defines how difficult it is to stretch or compress a material.
Updated On: Apr 27, 2026
- Stress is not a vector.
- Young's modulus is applicable only for solids
- Compressibility is relevant for solids, liquids and gases
- Elastomers have larger Young's modulus than metals
- Tension per unit area is equal to the tensile stress
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Young's modulus ($Y$) measures the stiffness of a material.
Step 2: Meaning
Metals are generally very stiff and have very high Young's modulus values (e.g., Steel $\approx 200$ GPa).
Step 3: Analysis
Elastomers (like rubber) are highly flexible and have very low Young's modulus values compared to metals. Therefore, statement D is false.
Step 4: Conclusion
Hence, option D is the incorrect statement.
