Question

The product of moment of inertia is 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

The question was asked in final exam.

The question is from Product of Inertia for an Area topic in division Moments of Inertia of Engineering Mechanics

Answer 1

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

Easy 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.
