3.0% (1 in 33) – several sections of the Main Western line between Valley Heights and Katoomba in the Blue Mountains Australia. [26] 3.0% (1 in 33) – The entire Newmarket Line in central Auckland, New Zealand; 3.0% (1 in 33) – Otira Tunnel, New Zealand, which is equipped with extraction fans to reduce chance of overheating and low visibility
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.
The steep slope may be curved. An element of the Second Empire architectural style (Mansard style) in the U.S. Neo-Mansard, Faux Mansard, False Mansard, Fake Mansard: Common in the 1960s and 70s in the U.S., these roofs often lack the double slope of the Mansard roof and are often steeply sloped walls with a flat roof. Unlike the Second Empire ...
Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement; the opposite condition is called slope instability or slope failure. The stability condition of slopes is a subject of study and research in soil mechanics , geotechnical engineering , and engineering geology .
An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction. It is also known as a tilt indicator, tilt sensor, tilt meter, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator.
A log–log plot of y = x (blue), y = x 2 (green), and y = x 3 (red). Note the logarithmic scale markings on each of the axes, and that the log x and log y axes (where the logarithms are 0) are where x and y themselves are 1. Comparison of linear, concave, and convex functions when plotted using a linear scale (left) or a log scale (right).
276 is the sum of 3 consecutive fifth powers (276 = 1 5 + 2 5 + 3 5). [1] As a figurate number it is the 23rd triangular number, [2] a hexagonal number, and a centered pentagonal number, the third number after 1 and 6 to have this combination of properties.
The standard mild slope equation, without extra terms for bed slope and bed curvature, provides accurate results for the wave field over bed slopes ranging from 0 to about 1/3. [11] However, some subtle aspects, like the amplitude of reflected waves, can be completely wrong, even for slopes going to zero.
