What you'll learn

  1. Axle at the rim: Parallel axes: I = Icm + Md²
  2. Spin on a diameter: Perpendicular axes: Iz = Ix + Iy
  3. Tangent in the plane: Two rules in a row
  4. Dumb-bell: Parts on a rod: shift each one, then add
  5. Punch a hole: A hole: take away the missing piece's I
  6. Pendulum with a disc: Joined parts: add each part's I about one axle
