For a single section used as a tension member, the given area is assum...
Explanation:
In tension members, the net area is the effective area available for resisting the tensile force. The net area is obtained by deducting the holes, fasteners or any other discontinuities from the gross area of the section. However, due to the presence of stress concentrations at the ends of the fastener holes, the actual stress in the member is higher than the nominal stress based on the net area.
To account for this, a reduction factor is applied to the nominal stress based on the net area, known as the fillet weld or fastener strength reduction factor (phi). This factor is typically 0.75 for bolts and 0.70 for welds.
To ensure that the actual stress in the member does not exceed the yield strength, the area of the section is increased by a certain percentage over the net area. This excess area is known as the gross area and is used to calculate the nominal stress based on the applied load.
For a single section used as a tension member, the given area is assumed to be 20% to 30% in excess of the net area. This means that the gross area is 20% to 30% larger than the net area. The exact value depends on the type of connection used and the size of the section.
The purpose of this excess area is to ensure that the actual stress in the member does not exceed the yield strength and to provide some margin of safety against unexpected loads or flaws in the material.
Therefore, the correct answer is option 'A'.
