Conservation of angular momentum

  1. Hi,
    I am by now very used to the concept of conservation of momentum and energy, however i had never solved a problem using the conservation of angular momentum.
    Well, in the case where angular momentum is conserved, we do not have a torque net. But, how this conservation law helps us to determine quantitatively ?
    Could you illustrate the concept with an example?
    Thank you very much.
