The area moment of inertia for a circular cross-section with a 6 mm diameter will be 64 mm⁴. Option B is correct.
The moment of inertia is defined as the resistance offered in the rotation of the moment.
Given data;
The diameter of circular section ,d = 6 mm
The moment of inertia is, I
The moment of inertia for the circular cross-section;
[tex]\rm I = \frac{\pi d^4}{64} \\\\ \rm I = \frac{3.14 \times 6^4 }{64} \\\\ I = 63.585 mm^4[/tex]
The area moment of inertia for a circular cross-section with a 6 mm diameter will be 64 mm⁴
Hence option B is correct.
