A dog-leg staircase A quarter-landing, on a dog-leg staircase, is made into an architectural feature, by the use of arches, vaulting and stained glass. A dog-leg is a configuration of stairs between two floors of a building, often a domestic building, in which a flight of stairs ascends to a quarter-landing before turning at a right angle and continuing upwards.

In mathematical analysis, the staircase paradox is a pathological example showing that limits of curves do not necessarily preserve their length. [1] It consists of a sequence of "staircase" polygonal chains in a unit square , formed from horizontal and vertical line segments of decreasing length, so that these staircases converge uniformly to ...
A stair, or a stairstep, is one step in a flight of stairs. A staircase or stairway is one or more flights of stairs leading from one floor to another, and includes landings, newel posts, handrails, balustrades, and additional parts. [4] In buildings, stairs is a term applied to a complete flight of steps between two floors.
Similarly, the root word "scala" does not mean "a flight of steps", but is the singular form of the plural noun "scalae", which can denote any of: "a flight of steps or stairs, a staircase; a ladder, [or] a scaling-ladder." [21] The alleged intended capitalization of "escalator" is likewise a topic of debate. Seeberger's trademark application ...
Falling down a flight of stairs or just a couple of steps is very common during infants’ first exposure to stair descent. Infants are more likely to fall down stairs than any other age group. [ 3 ] In the United States, approximately 73,000 children between the ages of 6 months and 2 years have reported injury on stairs or steps in 2009.
The maximum range condition is obtained at maximum lift/drag ratio (L/DMAX) The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1]
Designed by Thomas Heatherwick, [3] Vessel has 154 flights, 2,500 steps, and 80 landings, [3] with the total length of the stairs exceeding 1 mile (1.6 km). [4] The copper-clad steps, arranged like a jungle gym [ 5 ] and modeled after Indian stepwells , [ 4 ] [ 6 ] can hold 1,000 people at a time. [ 3 ]
Calculation of the balanced field length traditionally involves relying on an expansion program model, where the various forces are evaluated as a function of speed, and step-wise integrated, using an estimate for V 1. The process is iterated with different values for the engine failure speed until the accelerate-stop and accelerate-go ...
