A painter with 80 weight is on a 4 meters long platform. Platform has negligible weight. The painter is balanced by two cables. One is at the left end and the other one is 3.2 meters away from the first cable. a)What is the tension on the left cable and the right cable when the painter is in the middle of the platform b)Would the painter be able to move the right end of the platform without loosing balance. Calculate the tensions on the cables for that case and show that it leads to a negative tension.
