To calculate the Weight Per Foot (W/ft) of a steel bar:
\[ W/ft = \pi \left(\frac{D}{2 \cdot 12}\right)^2 \cdot d \]
Where:
The weight of a steel bar per foot is determined by the diameter of the bar and the density of the steel. It indicates how much a steel bar weighs for each foot of length. The weight is calculated using the volume of the bar and the density of the material. In this case, the formula takes into account the diameter of the bar and the density of steel (490 lbs/ft³) to determine the weight per foot.
Let's assume the following values:
Using the formula:
\[ W/ft = \pi \left(\frac{2}{2 \cdot 12}\right)^2 \cdot 490 \]
\[ W/ft = \pi \left(\frac{1}{12}\right)^2 \cdot 490 \approx 1.27 \text{ lbs/ft} \]
The Weight Per Foot is approximately 1.27 lbs/ft.
