Question

In the calculations of moments of inertia for an area about inclined axis we use the product of a moment of inertia. It is the the sum of _____________ and _________________

(a) Area and volume

(b) Volume and linear distance

(c) Moment of inertia at centroid and the product of the area and del dx and del dy

(d) Moment of inertia at base and the product of the area and del dx and del dy

This question was addressed to me in class test.

I would like to ask this question from Moments of Inertia for an Area About Inclined Axis in portion Moments of Inertia of Engineering Mechanics

Answer 1

Right choice is (d) Moment of inertia at base and the product of the area and del dx and del dy

Explanation: The product of moment of inertia is required as to design the structure of the body. This means that the designing of the body is majorly done by the help of the determination of the product of the moment of Inertia.
