The formula to calculate the steel plate mass is:
\[ M_{sp} = \frac{SL \times SW \times T}{12} \times 490 \]
where \( M_{sp} \) is the steel plate mass (lbs), \( SL \) is the length (ft), \( SW \) is the width (ft), and \( T \) is the thickness (in).
The steel plate mass is the weight of a steel plate, calculated based on its dimensions and material density. This is useful in various engineering and construction applications to determine the load and structural requirements.
Let's assume we have the following values:
Step 1: Multiply the length, width, and thickness:
\[ SL \times SW \times T = 10 \times 5 \times 0.5 = 25 \]
Step 2: Divide by 12 and multiply by 490:
\[ M_{sp} = \frac{25}{12} \times 490 \approx 1020.83 \]
Therefore, the Steel Plate Mass is \( M_{sp} \approx 1020.83 \text{ lbs} \).
