Question: Two weights with masses ma and mb > ma are suspended on a rope around a pulley according to the sketch. The pulley is then

Two weights with masses ma and mb>ma are suspended on a rope around a pulley according to the sketch. The pulley is then hung from a dynamometer from the ceiling. Determine:
a) The reading of the dynamometer if the pulley is locked so that it cannot rotate.
b) The reading of the dynamometer if the pulley is free to rotate.
The mass of the rope and the pulley is to be neglected. The length of the rope is kept constant. The gravitational constant is g.
Two weights with masses ma and mb > ma are
