Question

Hey guys, can you please check my answer and correct it? If I am missing something, please add :) Of course it is holiday season and no school but I like to keep practicing solving problems :) But of course I need you guys backup!

My answer: So the bridge is 1/100 of original proportion that means the original bridge will have a weight equivalent to 100 times the model bridge.
So what we need to do is 50N * 100 = 5000N

B) As we can see, the original bridge might sag because as we can see, it has a weight of 100 times greater than the model bridge.

Answer 1

Your answer for part `color (green)(A)` is correct , but i'm not so sure about `color (red)(B)` , that seems to me like schodinger's cat will survive or it will die . I would yet preferably say that the bridge will not sag , though it has greater weight but also size .' A model won't sag' shows the the orignal bridge shall neither . This may seem a little confusing but it can be made clear by some examples .
Consider a bridge Golden Gate Bridge, San Francisco, United States , all know it didn't sag . So, if You are making a model of it the model shall not sag either as per your explanation.
I believe the answer should be the the orignal bridge shall not sag , if i'm wrong someone from socratic community shall update my answer.
