  2. Grade (slope) - Wikipedia

    en.wikipedia.org/wiki/Grade_(slope)

    Slope may still be expressed when the horizontal run is not known: the rise can be divided by the hypotenuse (the slope length). This is not the usual way to specify slope; this nonstandard expression follows the sine function rather than the tangent function, so it calls a 45 degree slope a 71 percent grade instead of a 100 percent. But in ...

  5. Grading (earthworks) - Wikipedia

    en.wikipedia.org/wiki/Grading_(earthworks)

    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.

  6. Mount Washington Cog Railway - Wikipedia

    en.wikipedia.org/wiki/Mount_Washington_Cog_Railway

    It is the second-steepest rack railway in the world, after the Pilatus Railway in Switzerland, [3] with an average grade of over 25% and a maximum grade of 37%. The railway is approximately 3 miles (5 km) long and ascends Mount Washington's western slope, beginning at an elevation of approximately 2,700 feet (820 m) above sea level and ending ...

  7. Geometric design of roads - Wikipedia

    en.wikipedia.org/wiki/Geometric_design_of_roads

    The alignment is the route of the road, defined as a series of horizontal tangents and curves. The profile is the vertical aspect of the road, including crest and sag curves, and the straight grade lines connecting them. The cross section shows the position and number of vehicle and bicycle lanes and sidewalks, along with their cross slope or ...

  8. Slope - Wikipedia

    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.

  9. Pikes Peak Cog Railway - Wikipedia

    en.wikipedia.org/wiki/Pikes_Peak_Cog_Railway

    The average grade of the line would be 12% but would top out at 25%. Normal trains can not retain traction on the rails at grades steeper than 10%, so the railway would need to use a cog and rack system to help pull trains up the mountain and control the speed of the descent.
