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

Answer:
16, 74
Step-by-step explanation:
3x +10 + 12x +50 = 90
15x + 60 = 90
15x = 90 -60
15x = 30
x = 30/15
x = 2
3x + 10 = 3*2 +10 = 6 +10 = 16
12x + 50 = 12*2 +50 = 24 + 50 = 74
