The formula to calculate the scale speed is:
\[ SS = \frac{RS}{\sqrt{S}} \]
where \( SS \) is the Scale Speed (mph), \( RS \) is the real speed (mph), and \( S \) is the scale.
Scale speed is a concept used to determine the speed of a model or scaled-down version of an object based on its real-world speed. It is calculated by dividing the real speed by the square root of the scale. This is useful in various fields such as model railroading, aviation, and automotive design to understand how a scaled model would perform compared to its full-sized counterpart.
Let's assume we have the following values:
Step 1: Calculate the square root of the scale:
\[ \sqrt{S} = \sqrt{4} = 2 \]
Step 2: Divide the real speed by the square root of the scale:
\[ SS = \frac{60}{2} = 30 \text{ mph} \]
Therefore, the Scale Speed is \( SS = 30 \text{ mph} \).
