The scaffold is 18 m long. A 650-N box sits 3.0 m from the left end. What is the tension in each wire? left wire = 520 N; right wire = 130 N left wire = 640 N; right wire = 210 N left wire = 195 N; right wire = 975 N left wire = 295 N; right wire = 1000 N can someone show me how to do this please :)
Lets call left wire T1, right = T2 T1 = (200 x 9) + (650 x 15) = 11550 11550 = 18T1 11550/18 = 641.67 N T2 = (200 x 9) + (650 x 3) = 3750 3750 = 18T2 3750/18 = 208.33 N left wire = 640 N; right wire = 210 N
