7. In the figure, a barbell consists of two identical small spherical weights, each of mass 50 kg. These weights are connected by a thin 0.96-m rod with a mass of 24 kg. a. Find the moment of inertia of the barbell through the axis perpendicular to the rod at its center, assuming the two weights are small enough to be treated as point masses. Ix : Emr? I* = mir, +marz = ( 50 ) (0 96 ) + ( 24 ) (0 96)2 0.96 m- b. Find the moment of inertia if one of the weights is tripled. |0.96 m- c. What is the angular acceleration when the barbell with the additional mass is just released
