MiSP Topographic Maps Worksheet #2 - Hofstra …

10. Create a contour map by tracing the contour lines from the plastic overlay onto a sheet of blank white paper. Hint: The easiest way to trace this is to place the paper onto of the plastic overlay and then place the sandwiched paper and plastic against a window. The light from outside will allow you to see the contour

Contour lines that show a depression, crater, or sinkhole on a map are represented by dashed lines (hachure marks) on the inside of a contour line. The elevation of the first depression contour is the same as the nearest regular contour line.

A predictive model on surface roughness during internal ...

The surface roughness of nozzles has important influence on the quality of fuel atomization. The diameter of nozzles in aero engine is generally less than 1 mm. Because of the smaller diameter of the grinding wheel used, its stiffness is poor and thus the wheel tends to deflect under the grinding force. The deflection of grinding wheel has great influence on the …

Gradient and contour maps (video) | Khan Academy

Video transcript. - [Voiceover] So here I want to talk about the gradient and the context of a contour map. So let's say we have a multivariable function. A two-variable function f of x,y. And this one is just gonna equal x times y. So we can visualize this with a contour map just on the xy plane. So what I'm gonna do is I'm gonna go over here.
