SUMMARY
The discussion focuses on calculating the flexural stress in a steel column supporting a signboard with an area of 16.60 sq. m subjected to a wind velocity of 130 km/hr. Participants confirm that the overall force can be calculated using the sign's frontal area and wind speed, which can then be distributed between two cantilever beams. The flexural stress can be determined using the formula σ = My/I, where M is the moment, y is the distance from the neutral axis, and I is the moment of inertia.
