Three point objects with masses $m_1=1\mathrm{.}7kg,m_2=2\mathrm{.}0kg,$

and $m_3=2\mathrm{.}3kg$ are arranged in the configuration shown in

the figure. The distance to mass $m_1$ is $d_1=22cm$ and the

distance to mass $m_3$ is $d_3=42cm.$ The distances are

measured from the axis $O.$

What is the combined moment of inertia I for the three point

objects about the axis $O?$

$I=,kg*m^2$
