In the previous video, we discussed calculating two crucial parameters for a given cross-section. These parameters are the principal axes and the angle between the principal axes and the two horizontal and vertical axes that pass through the centroid of the cross-section. Knowing these parameters is crucial for analyzing the stress state of the cross-section and its behavior under different loading conditions. In this video, we will learn how to locate the neutral axis (N.A.) in cross-sectional analysis. The neutral axis is an important concept in structural engineering because it is the line along which the cross-section experiences no bending stress when subjected to bending moments. Furthermore, we will apply a moment to the cross-section and calculate the resulting stresses at the corner points.
