If we know the original dimensions (length, width, thickness) for all of the car parts (wheels, windows, headlights, etc.), we would simply multiply by the scale fraction in order to create accurate scale models for each of the parts. In this case, the scale model would have to be 10 inches long. To do this, simply multiply the original length (180 inches) by the scale fraction (1/18). We could start by calculating the total length of our model. This ratio, also called the scale factor, tells us that our model car is going to be 1/18th the size of the original.
In other words, the pieces of the model must be the same size relative to each other as they would be in real life.įor example, if we want to make a scale model of a car that is normally 15 feet long (180 inches), we would first decide how big our model is going to be relative to the actual car - say, a ratio of 1:18. It could be just as effective it it were made of plastic.įor a scale model to be useful, all of its parts have to be proportional to the same parts on the real thing. If she needed a scale model of a bridge to show the location of a new bridge that is set to be built, then the material does not matter. In such a case, the scale model would need to be made of that material in order for the test to provide any useful data. If an engineer is considering a new material for bridge building, she may create a miniature bridge and test it with a structure tester to determine its strength. However, for this scale model, the filmmaker would probably want to use much weaker materials so that the buildings easily crumble on impact. Real skyscrapers are made of steel frames and thick glass, among other strong materials.
A filmmaker may want to show New York skyscrapers being destroyed by asteroids. They are used by professionals such as engineers, architects, craftsmen, film makers, the military, and salespeople. Scale models allow us to demonstrate a behavior or property without examining the original object.
