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:
19w^2-m
Step-by-step explanation:
4w^2-m+15w^2
19w^2-m
Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
