A
a-ii, b-iv, c-i, d-iii
B
a-iii, b-ii, c-i, d-iv
C
a-ii, b-i, c-iv, d-iii
D
a-iv, b-ii, c-i, d-iii
Correct Answer
Option A
Detailed Explanation
Yield strength of mild steel is approximately 300 × 10 6 N m –2, Young's modulus of bone is given as 9.4 × 10 9 N m –2, and the cross-sectional area of the steel rope needed for the crane is calculated to be 3.3 × 10 -4 m 2.
