Question

Two m = 0.7 kg masses are located at either end of a 2.5 m long, very light and rigid rod as in the diagram. What is the rotational inertia of this system about an axis through the center of the rod?

______kg·m2

thanks a lot man

Answer 1

Since there is no diagram I assume that the axis of rotation is perpendicular to the rod.

2*0.7*(2.5/2)^2

2.19 kg m^2
