engineering recuitment FCI JE 2022 Mock Test for CE/ME/EE (Phase I & II) Strength of Materials Torsion of Shaft Moment of Inertia about Polar Axis
If a section has moment of inertia Ixx on x-axis and moment of inertia Iyy on the y-axis, then polar moment of inertia at the same section will be-
1
(Ixx + Iyy) / 2
2
(Ixx - Iyy) / 2
3
Ixx + Iyy
4
Ixx / Iyy
5
None of these
