Question

The center of gravity of a rectangle having h as height and w as width, one of its vertex is origin and its width is along x-axis is _____________

(a) (w/3,h/3)

(b) (w/4,h/4)

(c) (h/2,w/2)

(d) (w/2,h/2)

This question was addressed to me in an online interview.

I would like to ask this question from Centres of Gravity in portion Centres of Gravity, Moments of Inertia, Orthographic Reading and Conversion of Views of Engineering Drawing

Answer 1

The correct answer is (d) (w/2,h/2)

Easy explanation: Given a rectangle having h as height and w as width, one of its vertices is the origin and its width is along x-axis which is a symmetric planar object and for symmetrical objects the center of gravity lies at the intersection of axes.
