hollow sphere is attached to the end of a uniform rod. The sphere has a radius of 0.76 m and a mass of 0.48 kg. The rod has a length of 1.34 m and a mass of 0.42kg. The rod is placed on a fulcrum (pivot) at X = 0.38 m from the left end of the rod. (a) Calculate the moment of inertia (click for graphical table) of the contraption around the fulcrum. (b) Calculate the torque about the fulcrum, using CCW as positive. (c) Calculate the angular acceleration of the contraption, using CCW as positive. (d) Calculate the linear acceleration of the right end of the rod, using up as positive.

Question

For some reason, I keep getting an answer that is too small for this quesiton. For part a, I'm adding the moments of inertia together but must be doing something wrong in my calculations. Clarification would be super helpful!
