The sketch shows a painter’s scaffold in mechanical equilibrium. The person in the middle weighs 225 N, and the tension in each rope is 300 N. What is the weight of the scaffold?

Respuesta :

Answer:

The weight of the scaffold is 375 N.

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.
