Question 2

An object consists of a rod (of length 3.0 m and negligible moment of inertia) to which four small 2.0-kg masses are attached, one at each end and one at each point on the rod 1.0 m from each end. (The masses are one meter apart.) The moment of inertia of this object about an axis perpendicular to the rod and through one of the end masses:
 a. is 28 kgm2.
  b. is 12 kgm2.
  c. is 4 kgm2.
  d. cannot be uniquely determined until it is stated which inner mass the axis goes through.
