Two identical blocks of mass m are hung via massless strings over two pulleys of identical mass M and radius R, but different mass distributions. The bearings in the pulleys are frictionless and the strings do not slip as they unwind from their pulleys.

Once the systems are set into motion which pulley has the larger tension acting on it?

  1. The one on the left
  2. The one on the right
  3. Neither, they're equal
