Question

ABC is a triangular plate of uniform thickness. The sides are in the ratio shown in the figure. I_AB, I_BC and I_CA are the moments of inertia of the plate about AB, BC and CA axes respectively. Which one of the following relations is correct?

(a) I_AB > I_BC

(b) I_BC > I_AB

(c) I_AB + I_BC = I_CA

(d) I_CA is maximum

Answer 1

Correct option: (b) I_BC > I_AB

_Explanation:

The intersection of medians is the centre of mass of the triangle. Since distances of centre of mass from the sides are related
