Question

Two of the things of the composite materials are to be known so that their properties can be varied. Which of the following is one of them?

(a) Weight of the centre of gravity

(b) Weight of the centre of body

(c) Location of the centre of gravity

(d) Location of the centre of mass

I got this question by my college director while I was bunking the class.

This intriguing question originated from Composite Bodies in section Centre of Gravity and Centroid of Engineering Mechanics

Answer 1

Correct answer is (c) Location of the centre of gravity

To explain: The centre of the gravity’s location and the weight of the composite body is needed to be known. This means that if both of the quantities of the composite body is known then the properties of the body can be altered. Thus both are very important things to be known about the composite bodies.
