My question arises from trying to get the correct sign convention for a pulley that has two boxes attached by a massless rope. one box is to the left of the pulley and the other box is hanging down below the pulley.
If I take the counter clockwise direction to be negative, and set up my coordinate system as having the pulley at the origin, will the tensions as seen by the pulley both be negative because one is in the negative x direction and the other is in the negative y direction?
