Imagine you are part of a group of engineers who need to test a scale model of a footbridge. It will be a 1/20th scale model of the bridge. The footbridge will cross over a busy road and allow people to cross the road safely. How could a relatively small design error of 2 centimeters in the model system cause a significant problem in construction of the bridge? What if it was an error of 4 centimeters? (HINT: Create a ratio table.) Please explain your answer.
