Answer:
Step-by-step explanation:
mass of scaffold, m = 135 kg
mass of box, m' = 440 kg
let the tension in the left wire is T.
take moments about the right end.
According to the diagram,
135 x g x 3.3 + 440 x g x (6.6 - 1.7) - T x 6.6 = 0
4365.9 + 21128.8 - T x 6.6 = 0
T x 6.6 = 25494.7
T = 3862.8 N
