NEET Physics (general) MCQ Question
Which of the following statements about the mechanical properties of solids is correct?
The elastic limit of materials like rubber is typically higher than that of typical rocks.
Materials that can be stretched significantly while returning to their original shape are known as elastomers.
The shear component in structures is irrelevant to the design of load-bearing beams.
The stress-strain curve for materials like the aorta shows a well-defined plastic region.
Correct Answer
Detailed Explanation
Statement B correctly identifies elastomers as materials that can be stretched significantly and still return to their original shape, as mentioned in the context. Statement A is incorrect as rubber has a high elasticity but is not compared directly to rocks in terms of elastic limit. Statement C misrepresents the importance of shear components in structural design. Statement D is false because materials like the aorta do not have a well-defined plastic region.
