What is the difference between uniaxial and biaxial column?
If this neutral axis happens to be parallel to one of the coordinate axes, then we call this “uniaxial” bending. If the neutral axis (or the principle axis) is inclined with respect to the coordinate axis, then bending can be resolved into two components parallel to each coordinate axis, hence the term Biaxial Bending.
What causes biaxial bending?
Biaxial bending affects columns where the load is eccentric about both the axes in the plane of the column (eccentric load is a force placed upon a portion of a column which is not symmetric with its central axis, thereby producing bending).
What is a uniaxial crystal give an example?
This crystal is described by one optical axis and two principal refractive indices. Examples of uniaxial Crystals are calcite, KDP, quartz, rutile etc. When light beam passes through such crystal, it splits into o-ray and e-ray >>.
How many principal sections does uniaxial crystal have?
The plane containing the optic axis and the perpendicular to the pair of opposite faces of the crystal is known as principal section for that pair of faces of the crystal. Since the crystal has six faces, for each pair of opposite faces of the crystal, there are three principal sections.
What is biaxial bending in column?
Biaxial bending of columns occurs when the loading causes bending simultaneously about both principal axes. The commonly encountered case of such loading occurs in corner columns. Corner and other columns exposed to known moments about each axis simultaneously should be designed for biaxial bending and axial load.
What do we mean by biaxial bending of the column?
What is meant by biaxial crystal?
Abstract. Biaxial crystals, as their name indicates, have two optic axes along which light is propagated with the same velocity. In every other wave propagation direction there are two plane polarized components at right angles to each other and to the propagation direction; these have unequal velocities.
