Question

If an auto weighing 13,345 N causes a bridge to sag 0.0254 m, a truck weighing 26,690 N would cause the bridge to sag how many meters, assuming the truck was on the same spot as the auto had been?

How do I even set this up?

Answer 1

assume it acts as a simple spring.


13345=k*.0254
solve for k
then
26690=kx and solve for the new x.
