An object’s polar moment of inertia, J, represents itsresistance to twisting. For a cylinder, this moment of inertia isgiven by this formula: J = mr2 / 2 + m(l2 + 3r2) / 12 m is thecylinder’s mass (kg).

l is the cylinder’s length (m).

r is the cylinder’s radius (m).

Using this formula, determine the units for the cylinder’s polarmoment of inertia.
