The scaffold weighs 303 N and is 3 . 21 m long. Assume the window washer stands 1 . 35 m from the left end. What is the tension in the rope on the right? Correct answer: 362 . 621 N. Explanation: Let : W w = 502 N , W s = 303 N , d s = l s 2 = 1 . 605 m , d w = 1 . 35 m , and d 2 = 3 . 21 m . T 1 W w @ d w W s @ d s T 2 @ d 2 Applying the second (rotational) condition of equilibrium (with axis of rotation at T 1 ), summationdisplay τ = summationdisplay τ ccw- summationdisplay τ cw = 0 T 2 d 2- W w d w- W s d s = 0 T 2 = W w d w + W s d s d 2 = (502 N) (1 . 35 m) + (303 N) (1 . 605 m) 3 . 21 m = 362 . 621 N ....
