The formula to calculate the Rebar Weight is:
\[ RW = \pi \left( \frac{r}{12} \right)^2 \cdot L \cdot 490 \]
Where:
Rebar Weight refers to the weight of a steel reinforcing bar used in construction. The weight is calculated based on the radius and length of the rebar, along with a constant that represents the density of steel.
Example 1:
Using the formula:
\[ RW = \pi \left( \frac{0.5}{12} \right)^2 \cdot 10 \cdot 490 \approx 26.73 \, \text{lbs} \]
The Rebar Weight is approximately 26.73 lbs.
Example 2:
Using the formula:
\[ RW = \pi \left( \frac{0.75}{12} \right)^2 \cdot 20 \cdot 490 \approx 120.26 \, \text{lbs} \]
The Rebar Weight is approximately 120.26 lbs.
