Question

There is parallel axis theorem for the area, and it is can be used to determine the moment of inertia of an area about inclined axis.

(a) True

(b) False

This question was addressed to me by my college director while I was bunking the class.

This key question is from Moments of Inertia for an Area About Inclined Axis in portion Moments of Inertia of Engineering Mechanics

Answer 1

The correct answer is (b) False

The explanation is: There is no perpendicular axis theorem for the area. In spite, there is the theorem as parallel axis for any area. Thus we have the theorem which is used to add the two mutually perpendicular moment of inertias.
