If a dent in an aluminum A/C fin measures one inch, what is the approximate size of the hail that caused the dent?

1. 1.5"

2. 1.0"

3. 0.8"

4. 1.25"

The correct answer is: 1.25"

When evaluating the relationship between the size of a dent in an aluminum A/C fin and the size of the hail that caused it, it's important to understand the mechanics of how hail impacts surfaces. Typically, the size of the dent is larger than the size of the hailstone because when hail strikes a surface, it compresses the metal without perfectly transferring its dimensions. In this scenario, a dent measuring one inch generally suggests a hailstone that is slightly smaller. Research and industry standards often indicate that the hail that creates such dents can be roughly 20-30% smaller than the dent itself. Therefore, if the dent measures one inch, this correlates to an approximate hail size of about 0.8 to 1.0 inches. Selecting 1.25 inches, as noted, represents a slightly larger size than is typical for hail creating a one-inch dent, hence it does not provide the most accurate estimation. Conversely, a 0.8-inch hailstone is likely the most aligned with the one-inch dent but doesn't fit as directly into the estimate based on size comparison used in assessing impairments from hail. Thus, while one could argue for a small diameter variation, the context of dent-to-hail size ratios makes a smaller measurement like
