Allowable Area Calculator

Formula

The formula to calculate the Allowable Area (AA) is:

\[ \text{AA} = \frac{\text{S}}{\text{L}} \]

Where:

\(\text{AA}\) is the allowable area (square feet)
\(\text{S}\) is the span (feet)
\(\text{L}\) is the load (pounds per square foot)

Allowable Area Definition

Allowable area is a term used in engineering and construction to describe the maximum area that can safely support a given load without exceeding the material’s stress limits or causing structural failure. This concept is crucial for ensuring the safety and integrity of buildings, bridges, and other structures.

Example Calculation

Let's assume the following values:

Span (S) = 100 feet
Load (L) = 50 pounds per square foot

Using the formula:

\[ \text{AA} = \frac{100}{50} = 2 \text{ square feet} \]

The Allowable Area (AA) is 2 square feet.
