Two beams are joined end to end and hinged at the left end.  The left beam has a mass of 10 kg and the right beam has a mass of 12.2 kg.  Determine the magnitude of the gravitational torque about the hinge.  Use g = 10 N/kg.  Enter units as Nm.  Hint:  You can either determine the center of mass of the combined object and exert the total gravitational torque from there or you can treat each beam individually and add the torques of each.
