Biaxial joints allow for movement in two planes or axes. A common example of a biaxial joint is the wrist, which allow for movement side to side, and also allows for movement up and down. It can be difficult to determine whether a joint is biaxial or multiaxial, because when the biaxial joint moves in both directions at the same time, it appears to have the multiaxial quality of being able to move in any plane or axes.

Certain substances will split a ray of light into two slightly different paths by polarisation. If a crystal transmits light without splitting it in this way when the light is incident on the crystal in only one direction then the crystal is said to be uniaxial. If light is transmitted when it is incident in either of two directions then the crystal is said to be biaxial. Please see the links.

Aircraft structures can be fabricated from fibre reinforced polymers such as carbon fibre/epoxy and glass polyester composites. They are normally loaded in more than one direction at once, that is, they are biaxially loaded. It has been recognized that limiting the evaluation of a material characteristic to uniaxial tests can lead to a misrepresentation of the behaviour of a material in an engineering structure. So, using more realistic loading during the test, i.e. introducing biaxial conditions, leads to a more accurate representation of the expected behaviour of the structure in-service, which could in turn lead to far wider use of composites. Advantages of Biaxial Loading: Biaxial Loading can be used to measure basic material properties and also the behaviour of specific features of interest under biaxial loading conditions. This would include open holes, holes containing fasteners, impact damage sites and loaded fasteners. This last type of test is made possible by the bolt loading facility. The use of biaxial testing represents a major step forward in understanding their properties and establishing a way forward to the next generation of advanced structures, leaving traditional 'black aluminium' designs in the past.

The difference between a uniaxial and a biaxial crystal is that a uniaxial crystal has 1 optic axes, while a biaxial crystal has 2 optic axes.

yes
There are two types uniaxial or biaxial.

Biaxial cable consists of two side-by-side coaxial cables held together by an outer insulating jacket.

A bisectrix is the line bisecting the angle between the optic axes of a biaxial crystal.
