Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What defines geometric similarity?

  • All linear dimensions of models should match the prototype
  • Models are randomly scaled
  • Only some dimensions are considered

💡 Hint: Think about replication of the size and shape.

Question 2

True or False: The discharge in a model should be greater than the prototype discharge.

  • True
  • False

💡 Hint: Consider what happens as you scale down.

Challenge Problems

Push your limits with challenges.

Question 1

Design a model for a prototype bridge that is 300 meters long, 30 meters high, and 10 meters wide. If the model is to be built at a scale of 1:50, what will the model's dimensions be?

💡 Hint: Remember to divide each dimension of the prototype by 50.

Question 2

Evaluate how a model of a storm surge barrier that is scaled down by the ratio of 1:200 could influence an engineer’s decisions before constructing the full-scale barrier.

💡 Hint: Consider what valuable information can be gathered through physical observation of the model.
