NEET Physics Elastic Behavior MCQ Question
Which of the following statements about the elastic behavior of materials is correct?
Steel exhibits more elasticity than copper, brass, and aluminum, making it suitable for heavy-duty applications.
Rubber follows Hooke's law throughout its entire elastic range, allowing it to return to its original shape.
The elastic limit of a material is the point beyond which it can no longer return to its original dimensions.
Ductile materials have their ultimate tensile strength and fracture points closely spaced on the stress-strain curve.
Correct Answer
Detailed Explanation
Steel is indeed more elastic than copper, brass, and aluminum, which is why it is preferred for heavy-duty machines. Rubber does not strictly follow Hooke's law, and the elastic limit is where permanent deformation begins, while ductile materials have a greater distance between ultimate tensile strength and fracture points.
