Neutral Plane - Plane in the beam where all bending stresses are zero. It is the reference point for the integral defining the Area Moment of Inertia, I.
Line Pressure Load - Out of convenience, beam theory defines the units for a pressure load as [N/m], as opposed to real pressure units [N/m2]. To convert a real pressure to this line pressure for beams, multiply the true pressure by the beam width,
