Problem

Three particles are fixed relative to a straight line axis as follows: •

2\,\text{kg}

20\,\text{cm}

•

3\,\text{kg}

40\,\text{cm}

•

5\,\text{kg}

60\,\text{cm}

Calculate the moment of inertia about the axis. (a)

1.87\,\text{kg m}^2

(b)

2.36\,\text{kg m}^2

(c)

0.236\,\text{kg m}^2

(d)

4.72\,\text{kg m}^2
