where is the volume fraction of the fibers in the composite (and is the volume fraction of the matrix).. If it is assumed that the composite material behaves as a linear-elastic material, i.e., abiding Hooke's law = for some elastic modulus of the composite and some strain of the composite , then equations 1 and 2 can be combined to give
Axial loading is defined as applying a force on a structure directly along a given axis of said structure. [1] In the medical field, the term refers to the application of weight or force along the course of the long axis of the body. [2] The application of an axial load on the human spine can result in vertebral compression fractures. [3]
Two types of molecules having axial chirality: allenes (left) and binaryl atropisomers (right) In chemistry, axial chirality is a special case of chirality in which a molecule contains two pairs of chemical groups in a non-planar arrangement about an axis of chirality so that the molecule is not superposable on its mirror image.
As examples, in PF 5 the axial P−F bond length is 158 pm and the equatorial is 152 pm, and in PCl 5 the axial and equatorial are 214 and 202 pm respectively. [ 2 ] In the mixed halide PF 3 Cl 2 the chlorines occupy two of the equatorial positions, [ 2 ] indicating that fluorine has a greater apicophilicity or tendency to occupy an axial position.
Recall that the spin tensor (the skew part of the velocity gradient) can be expressed as = ˙ + (˙ ˙) Thus for pure rigid body motion = ˙ = Alternatively, we can consider the case of proportional loading when the principal directions of strain remain constant. An example of this situation is the axial loading of a cylindrical bar.

1,1 ′-Bi-2-naphthol (BINOL) is an organic compound that is often used as a ligand for transition-metal catalysed asymmetric synthesis.BINOL has axial chirality and the two enantiomers can be readily separated and are stable toward racemisation.
The difference between now and the past is that such a decision is available not simply to 16-to-18-year-old high school recruits, who are also easily swayed by things like jersey colors ...
