The keystone effect is the apparent distortion of an image caused by projecting it onto an angled surface. It is the distortion of the image dimensions, such as making a square look like a trapezoid, the shape of an architectural keystone, hence the name of the feature.
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 ...
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 ...

Orthographic projection (also orthogonal projection and analemma) [a] is a means of representing three-dimensional objects in two dimensions.Orthographic projection is a form of parallel projection in which all the projection lines are orthogonal to the projection plane, [2] resulting in every plane of the scene appearing in affine transformation on the viewing surface.
Adobe Bridge is a free digital asset management app made by Adobe Inc. and first released with Adobe Creative Suite 2. It is a mandatory component of Adobe Creative Suite, Adobe eLearning Suite , Adobe Technical Communication Suite and Adobe Photoshop CS2 [ 3 ] through CS6.
In micromechanical context the skewness angle can be understood as a macroscopic measure of the magnitude of internal entropy of the (macroscopic) Cauchy stress tensor. In this sense that its value determines degree of order of the population of micro pure shears (directional dipoles) generating the specific macroscopic stress state.
