Question

Consider a model steel bridge that is 1/100 the exact scale of the real bridge that is to be built.

a. If the model bridge weighs 50 N, what will the real bridge weigh?
b. If the model bridge does not appear to sag under its own weight, is this evidence the real bridge, built exactly to scale, will not appear to sag either?

Answer 1

A. 50x9.8x1/100 = 500 000N B. The evidence is sufficient, so yes.
