Rotation about a fixed point --- dynamics?
two strings are hanging vertically from the ceiling and are attached to the ends of a massless rod, which is horizonal. there are two point masses that are positioned on the rod.
If one of the supporting strings is cut would the tension in the uncut string immediately after the cut be smaller if both masses are positioned in the center of the rod or if one is on each end?

Should be the same since the torque would be:
T = r x F = r x (2mg) = 2m (r x g)
or
T = 2r x mg = 2m (r x g)
