Answer:
The weight of the scaffold is 375 N.
Step-by-step explanation:
It is given that,
The weight of the person in the middle, W = 225 N
Tn tension in each rope, T = 300 N
Let w is the weight of the scaffold. On equilibrium, the net forces can be written in terms of :
w + 225 = 300 + 300
w = 375 N
So, the weight of the scaffold is 375 N. Hence, this is the required solution.
