What is a Scaled Model?
A scaled model (prototype) is a model that is either much larger or smaller than a typical prototype or an actual size model.
Why Scaled Model?
Scaled models help the design process in that they may be experienced (tested, inspected, modeled and varied) at the scale that is convenient for human interaction.
This video gives you an overview of scaled model
This video gives you a walk-through on how to apply Dimensional Analysis:
Here is an example of Scaled Model method used for AV case study and additional examples of Dimensional Analysis.
