When is the Y-Axis section modulus used to calculate the bending stress in an I-beam? If the beam is conventionally loaded (simply supported , and load is imparted in the vertical direction on top of the flange), does bending occur about the "Y" or "X" direction? Subsequently, do you use the corresponding section modulus to calculate the stress?? Thank you for your input.

I agree with jsha811 that this is a very basic question and that you should thoroughly review the principles of beam theory before applying any of this to a real problem.

As someone said above, the section modulus axis is perpendicular to the loading direction.
Y-Y axis would be used on an I shape if it happened to be laid flat OR if it was subject to lateral loading such as wind or seismic,
