in a horizontal position by a vertical cable at each end. A window washer of mass 68 kg stands at a point 0.58 m from the end. What is the tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable?
Its all correct except you put 57 instead of 51 in the last equation.
(a) Taking moments about the farther end we have [TN = tension in near end cable nad TF = tension in farther end cable] 51*2.85*9.8 + 68*(5.7-0.58)*9.8 = TN*5.7 or TN = 848.5 N (b) TF + TN = (57+68)*9.8 = 376.5 N
