Physics-Elastic Behavior
NEET Physics Elastic Behavior MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a stress-strain diagram for a solid material, where the region OA represents the proportional limit. Which of the following best describes this region in terms of its relation to Hooke's Law and the material's behavior?
A
The stress is directly proportional to the strain, obeying Hooke's Law.
B
The material exhibits plastic deformation and does not return to its original shape.
C
The stress-strain curve is non-linear, indicating the material is an elastomer.
D
The material's deformation is permanent, indicating a failure point.
Correct Answer
Option A
Detailed Explanation
In the proportional region within the elastic limit (region OA), stress is directly proportional to strain, obeying Hooke's Law, as indicated by the NCERT context.
