Answer 2

Correct Answer:

A. db12

Step-by-step explanation:

Moment of inertia of the rectangular section about X-X axis passing through the C. G. of the section (parallel to the width):

Iₓₓ=$\frac{bd^3} {12}$

Moment of inertia of the rectangular section about Y-Y axis passing through the C. G. of the section (parallel to the depth):

Iyy=$\frac{bd^3} {12}$

Hence, the final answer will be A. db12
