This exercise is about calculating the moment of inertia for a given system of masses and understanding how the distribution of mass affects rotational motion about different axes.

Expert Solution

Step 1 :Introduction

The moment of inertia of an object about an axis is given by the formula $I = m l^{2}$ ,where m is the mass of the object and l is the distance of the object from the axis of rotation.

In axis 1 , there are two objects lying on the considered axis of rotation , for which the distance from the axis of rotation to the object will be zero. In axis 2 , only one object is lying on the axis .

The height of an equilateral triangle with side a is given by the formula $h = \frac{\sqrt{3} a}{2}$ , so the value of each side of the triangle will be $a = \frac{2 h}{\sqrt{3}}$ .
