a 617 N window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 385 N and is 4.48m long. Assume the window washer stnads 1.06m from the left end.What is the tension of the rope on the right?What is the tension of the rope on the left?Answer in units of N.
Set up a net moment equation. To find the tension in the rope on the right use the spot where the left rope connects to the scaffold as rotation point. Then it's just force times distance for the rope and the man and the net moment will be zero. For the the left end use the right side as your rotation point. Tr (x1) + Wm(x2) = 0 Tr = Tension in right rope x1 = length of board Wm = Weight of man x2 = man's distance from left rope.
