NEET Physics Young's Modulus MCQ Question
Consider a crane designed to lift 10 tonnes using a steel rope. The rope must not exceed the elastic limit during operation. Which parameter of the rope is crucial to ensure that it does not deform permanently?
Cross-sectional area
Length of the rope
Diameter of the pulleys
Motor speed
Correct Answer
Detailed Explanation
The cross-sectional area of the rope should be such that the stress does not exceed the yield strength of the material, ensuring it remains within the elastic limit as per the NCERT context.
