Picture 2 towers, 2 ft apart and 2 ft high. The left tower is just an anchor point for a string and the right tower has a roller on top for the string to roll over. Now I put a 2# weight in the middle of the string allowing it to pull the string over the roller until it touched the floor.
Now I attach a scale to the sting, holding the string so it just barely touches the roller and is at 90 degrees to the tower. I measure the weight every inch as I ull the string back to level.
Now I do the same thing again twice but once I pull the string down at parallel to the tower and the next time at 45 degrees.
Question 1, will the scale read the same regardless of the angle I pull it.
Questin 2, I know the weight would have 4 ft# of energy if it dropped with no friction but how will the scale read as I pull the weight back up until the string is straight?
