Solution
Correct Answer:
Stress/strain
Within the elastic limit, according to Hooke's Law, stress is proportional to strain. The constant of proportionality for longitudinal stress and strain is called Young's Modulus (Y): Y=Longitudinal StrainLongitudinal Stress=ΔL/LF/A=AΔLFL
- It is a characteristic property of the material and does not depend on the dimensions of the object.
- It indicates the stiffness of the material: higher Y means the material is harder to stretch.
This easy difficulty physics question is from the chapter properties of solids and liquids, covering the topic of young's modulus. It appeared in the 2025 exam.
