  2. Grade (slope) - Wikipedia

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

    as a ratio of one part rise to so many parts run. For example, a slope that has a rise of 5 feet for every 1000 feet of run would have a slope ratio of 1 in 200. (The word "in" is normally used rather than the mathematical ratio notation of "1:200".) This is generally the method used to describe railway grades in Australia and the UK.

  3. Drainage gradient - Wikipedia

    en.wikipedia.org/wiki/Drainage_gradient

    Typically on straight road sections, the drainage gradient is at least 1–3% due to the normal cross slope of 1–3%. In curved sections the drainage gradient is higher, and may often reach 5–12% due to superelevated CS that may reach 5–8% in areas with icy roads and up to 12% in areas without icy roads.

    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.

  5. Capital allocation line - Wikipedia

    en.wikipedia.org/wiki/Capital_allocation_line

    An example capital allocation line. As illustrated by the article, the slope dictates the amount of return that comes with a certain level of risk. Capital allocation line (CAL) is a graph created by investors to measure the risk of risky and risk-free assets. The graph displays the return to be made by taking on a certain level of risk.

    From Figure 8, the intersection of 1 / β and A OL occurs at f 0 dB = 1 kHz. Notice that the peak in the gain A FB near f 0 dB is almost gone. [note 2] [9] Figure 9 is the phase plot. Using the value of f 0 dB = 1 kHz found above from the magnitude plot of Figure 8, the open-loop phase at f 0 dB is −135°, which is a phase margin of 45 ...

    The template can format a brick chart within 1/6 second, so 3 brick charts could appear within a page and add only 1/2 second to reformat, or edit-preview. The initial creation of the template occurred in August 2009; however, the alignment for display problems with overlapped bars was fixed in September 2012, over 3 years later.
