A structure consists of three small objects (which may be treated as point particles) connected by massless rigid rods as shown.

a. Find the moment of inertia of this structure about axis I through the center of object A, perpendicular to the plane of the diagram.

b. Find the moment of inertia of this structure about axis 2 through the centers of objects B and C and in the plane of the diagram.

Axis 1 0.5 m 0.3 m mA = 0.2 kg Axis 2 m = 0.3 kg 0.4 m m = 0.4 kg
