Interaxis

The doors, windows, niches, and the like, are then placed centrally in the interaxes.

The small order is 16½ braccia high, i.e. eleven times the diameter of the base of the columns (which is 1½ braccia) and one and a half times the interaxis.

The analyses performed have shown the importance of the longitudinal distance (interaxis) for in-series applications.

Indeed, when the light-frame elements and the timber-frame ones are of different widths (the studs/mullions with respect to the posts and the rafters with respect to the sloped beams), and when there is a constant interaxis from center to center between them, the span between them cannot be constant; and vice versa, when the span is kept constant, the interaxis from center to center cannot be constant.

The principles of analytical geometry afford the means of determining how much the interaxes of the regular octahedron must be increased or diminished to equal the interaxes in these different forms.

Owing to this I was only able, by breaking a number of the quartz pieces, to obtain one small crystal representing a distorted rhombic dodecahedron ∞ 0(110), i.e., one extended in the line of an octahedral or trigonal interaxis, giving it the appearance of an hexagonal prism terminated by a rhombohedron (see fig. 2) in striking resemblance to dioptase.

When the position is as given in the stereographic projection in Fig. 265, the angle over the axial-plane polar edges is the more acute, but if the pole were placed nearer to the crystallographic than to the interaxis, as in the case of the dihexagonal pyramid {2131} of beryl shown in Fig . 266, the case would be reversed.

In the traditional valence bond approach above, the decrease of the bron position parameter improves the bond strength of the (sp³)_z hybrid, but it increases the misfit between direction of the boron-metal interaxis and direction (z-axis) of (sp³)_z hybrid.
