Rigid rods of negligible mass lying along the y axis connect three particles (Fig. P10.20). The system rotates about the x axis with an angular speed of 1.20 rad/s.(adsbygoogle = window.adsbygoogle || []).push({});

(a) Find the moment of inertia about the x axis.

So isnt the moment of inertia given by the sum of mr so..

(4kg)(3m)+(2kg)(-2m)+(3kg)(-4m) = -4?
