The formula to calculate the net sectional area (An) is:
\[ An = Ag - (N \times Ah) \]
Where:
The net sectional area is the effective area of a structural member after accounting for any reductions due to holes or other discontinuities. It is an important parameter in structural engineering, as it determines the strength and load-carrying capacity of the member. The net sectional area is typically less than the gross sectional area, which is the total area of the member without any deductions.
Let's assume the following values:
Using the formula to calculate the net sectional area (An):
\[ An = Ag - (N \times Ah) = 100 - (4 \times 2) = 92 \text{ square units} \]
The Net Sectional Area (An) is 92 square units.
