We often use the centre of mass of the composite area to calculate the moment of inertia. The centre of mass for these composite body is the ratio of ________ to _________
(a) The product of centroid and mass to the total weight
(b) The addition of centroid and weight to the total weight
(c) The subtraction of centroid and weight to the total weight
(d) The product of centroid and mass to the total mass
I had been asked this question by my school principal while I was bunking the class.
This intriguing question originated from Moment of Inertia for Composite Areas topic in division Moments of Inertia of Engineering Mechanics
