Two thin rods (each of mass 0.20 kg) are joined together to form a rigid body . One of the rods has length L1= 0.40 m, and the other has length L2 = 0.50 m.What is the rotational inertia of this rigid body about (a) an axis that is perpendicular to the plane of the paper and passes through the center of the shorter rod and (b) an axis that is perpendicular to the plane of the paper and passes through the center of the longer rod?

Question

Two thin rods (each of mass 0.20
kg) are joined together to form a rigid
body . One of the
rods has length L1= 0.40 m, and the
other has length L2 = 0.50 m.What is
the rotational inertia of this rigid body
about (a) an axis that is perpendicular
to the plane of the paper and passes
through the center of the shorter rod
and (b) an axis that is perpendicular to
the plane of the paper and passes
through the center of the longer rod?
