# Neutral axis

## Definitions

• Webster's Revised Unabridged Dictionary
• Neutral axis (Mech) that line or plane, in a beam under transverse pressure, at which the fibers are neither stretched nor compressed, or where the longitudinal stress is zero. See Axis.
• Neutral axis (Mech) the line of demarcation between the horizontal elastic forces of tension and compression, exerted by the fibers in any cross section of a girder.

Hence the ionization ﬁeld in the model became 2D (keeping the axial symmetry about the solar rotation axis) and time-dependent, and since the gas in ﬂow axis and solar rotation axis are inclined at an angle to each other, the model of neutral hydrogen distribution in the inner heliosphere became 3D and time dependent.
