A system of skew coordinates is a curvilinear coordinate system where the coordinate surfaces are not orthogonal, [1] in contrast to orthogonal coordinates.. Skew coordinates tend to be more complicated to work with compared to orthogonal coordinates since the metric tensor will have nonzero off-diagonal components, preventing many simplifications in formulas for tensor algebra and tensor ...
Colorado Street Bridge, an example of a false skew arch. The strength of a regular arch (also known as a "square" or "right" arch) comes from the fact that the mass of the structure and its superincumbent load cause lines of force that are carried by the stones into the ground and the abutments without producing any tendency for the stones to slide with respect to one another.
Southdown Road Skew Bridge looking along the barrel. Note the substantial retaining wall to the left of the arch. The easiest way to visualise Boucher's concept for the ribbed skew arch is to consider a regular arch bridge that carries the railway at right angles across the road and then to slice it vertically at regular intervals along the axis of its barrel, the planes all being parallel ...
The bridge has an unusually great skew angle of 63°, [note 2] requiring a large skew span of 42 feet (13 m) for a bridge with a relatively small clear span of only 18 feet (5.5 m). [10] As the bridge is in open countryside and the line is curved near this point, it is unclear why such a difficult and expensive bridge was chosen, rather than ...

In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam).Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1]

Bowley's measure of skewness is γ(u) evaluated at u = 3/4 while Kelly's measure of skewness is γ(u) evaluated at u = 9/10. This definition leads to a corresponding overall measure of skewness [23] defined as the supremum of this over the range 1/2 ≤ u < 1. Another measure can be obtained by integrating the numerator and denominator of this ...
