ISection.compute_neutral_axis
- ISection.compute_neutral_axis(N=0.0, Mx=0.0, My=0.0)[source]
Compute the neutral axis slope and intercept for the section.
- Parameters:
- Nfloat, optional
Axial force (default is 0.0).
- Mxfloat, optional
Bending moment about the x-axis (default is 0.0).
- Myfloat, optional
Bending moment about the y-axis (default is 0.0).
- Returns:
- tuple
Slope of the neutral axis (dy/dx) or None for vertical axis, intercept of the neutral axis in local coordinates.
- Raises:
- ValueError
If the neutral axis is undefined for pure axial load.
