In an effort to be the star of the half-time show, a majorette twirls an unusual baton made up of four spheres fastened to the end of very light rods (see figure). Each rod is 1.30 m long. (a) Find the moment of inertia of the baton about an axis perpendicular to the page and passing through the point where the rods cross. 0.4225 kg . m 2 (b) The majorette tries spinning her strange baton about the axis OO', as shown in the figure. Calculate the moment of inertia of the baton about this axis. 0.2535 kg . mz EXERCISE HINTS: GETTING STARTED | I'M STUCK! Yet another bizarre baton is created by taking four identical balls, each with mass 0.293 kg, and fixing them as before except that one of the rods has a length of 1.07 m and the other has a length of 1.60 m. (a) Calculate the moment of inertia of this baton when oriented as shown in the figure. 1 = kg . m2 (b) Calculate the moment of inertia of this baton when oriented as shown in the figure, with the shorter rod vertical 1 = kg . m2 (c) Calculate the moment of inertia of this baton when oriented as shown in the figure, but with longer rod vertical I = kg . m2 Need Help?

PROBLEM In an effort to be the star of the half-time show, a majorette twirls an unusual baton made up of four spheres fastened to the ends of very light rods (Figure (a)). Each rod is 1.0 m long. (a) Find the moment of inertia of the baton about an axis perpendicular to the page and passing through the point where the rods cross. (b) The majorette tries spinning her strange baton about the axis OO', as shown in Figure (b). Calculate the moment of inertia of the baton about this axis. STRATEGY In Figure (a), all four balls contribute to the moment of inertia, whereas in Figure (b), with the new axis, only the two balls on the left and right contribute. Technically, the balls on the top and bottom in Figure (b) still make a small contribution because they're not really point particles. However, their contributions can be neglected because the distance from the axis of rotation of the balls on the horizontal rod is much greater than the radii of the balls on the vertical rod.
