what I mean is the force is 175 and 350 pounds force. that 525 pulls the pulley shaft down and the pulley shaft exerts 525 pounds on its mount since the position of the pulley does not move.
Now the force on the rope is 175 in one direction and 350 (for a sum of 175) in the other so it moves in the direction of the heavy weight.
