For example, a self-aligning nut allows the nut to find its own perpendicularity to the thread axis by floating via a pair of spherical bearing surfaces ( a ball-in-cup arrangement ).
22.
There are several constraints that may be applied between the entities or bodies depending much on their actual natural geometry; sometimes these are also referred to as mates and include : collinearity, perpendicularity, same dimension.
23.
Even with some inaccuracies in polar alignment or the perpendicularity of the mount, setting circles can be used to roughly get to a desired object's coordinates, where a star chart can be used to apply the necessary correction.
24.
The time increases because the central axis of the pendulum is aligned with the axis of rotation of the Earth at the North Pole and then the angle of misalignment increases as the latitude decreases to the point of perpendicularity at the Equator.

Its personnel fly first class, retire to generous pensions ( instead of working the revolving door with the private sector ), and in general convey the aura of worldly perpendicularity that is necessary in order to persuade the best bankers to confide one-anothers'secrets.
27.
Because the magnitude of the cross product goes by the sine of the angle between its arguments, the cross product can be thought of as a measure of " perpendicularity " in the same way that the dot product is a measure of " parallelism ".
28.
I'd like to find a set of axioms for perpendicularity that are visually obvious, that don't rely for their intuitive justification on the additional concept of congruence ( beyond what is present already in the affine structure ), and that give us all of Euclidean geometry.
29.
Since perpendicularity to "'? "'1 means that the first two coordinates are equal, E 7 is then the subset of E 8 where the first two coordinates are equal, and similarly E 6 is the subset of E 8 where the first three coordinates are equal.
30.
In an inner product space, the concept of perpendicularity is replaced by the concept of orthogonality : two vectors "'v "'and "'w "'are orthogonal if their inner product \ langle \ mathbf { v }, \ mathbf { w } \ rangle is zero.
