Engineering Mechanics | Distribution | Statical Moment Qy | Manual Calculation | z-t Distribution

This video discusses the distribution of the statical moment.
First, we draw the z-t distribution, then integrate the individual surfaces, which leads to determination of the statical moment Sy.

The s-coordinates help here. The sensible orientation of these coordinates has a great effect on this distribution.

This video shows the difference between calculation by the central axes and a more precise calculation.

Since, in the simplified system, the height goes from the web to the central axes of the flanges, a higher value of the governing statical moment will result.
