Moment of Inertia: in the Figure, a Weightlifter's Barbell Consists

Short Answer

Moment of inertia: In the figure, a weightlifter's barbell consists of two identical uniform spherical masses each with radius 0.17 m and mass of 50 kg. The weights are connected by a 0.96-m uniform steel rod with a mass of 12 kg. Find the moment of inertia of the barbell about the axis through the center (see figure).
