A
Young's Modulus is defined as the ratio of tensile stress to tensile strain.
B
Young's Modulus applies only to materials under compressive stress.
C
Young's Modulus is a measure of a material's ability to deform permanently.
D
Young's Modulus is irrelevant in determining the thickness of a steel rope for cranes.
Correct Answer
Option A
Detailed Explanation
Young's Modulus is indeed defined as the ratio of tensile stress to tensile strain, which is essential for ensuring that materials like steel ropes do not exceed their elastic limit when lifting heavy loads.
