A stair flight is a run of stairs or steps between landings. A stairwell is a compartment extending vertically through a building in which stairs are placed. A stair hall is the stairs, landings, hallways, or other portions of the public hall through which it is necessary to pass when going from the entrance floor to the other floors of a building.
l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A ...
The cars are permanently attached to the cable, which stops, starts and reverses as required. Cars are often custom built for the slope, with specially raked seating and steps rather than a sloped floor. Taken to its logical conclusion as the slope becomes vertical, a funicular becomes an elevator.
Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
Section through railway track and foundation showing the sub-grade. Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.
A stairwell or stair room is a room in a building where a stair is located, and is used to connect walkways between floors so that one can move in height. [1] Collectively, a set of stairs and a stairwell is referred to as a staircase or stairway .
Slope or gradient of a line describes its steepness, incline, or grade, in mathematics. Slope may also refer to: Slope landform, a type of landform; Grade (slope) of a topographic feature or constructed element; Piste, a marked track for snow skiing or snowboarding; Roof pitch, a steepness of a roof; Slope, a 2007 album by Steve Jansen
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 ...
