Moment of Inertia MixedHardQuestion 6195

Question

Two thin rods (each mass M, length L) form '+' shape. MI about axis through centre perpendicular to both:
  1. A
    ML²/6
    Correct
  2. B
    ML²/12
  3. C
    ML²/3
  4. D
    2ML²/3

Correct answer

ML²/6

Explanation

Each rod: I = ML²/12 about its centre (perpendicular axis). Two rods: I_total = 2×ML²/12 = ML²/6.
