Use vertical curves to smooth changes in vertical direction. A crest curve occurs when the arc of the curve is below the VPI. A sag curve occurs when the arc is above the VPI. Typically, vertical curves are symmetrical. This means the tangent length from VPC to VPI equals the tangent length from VPI to VPT. Figure 2 illustrates the components of a vertical curve.
write a function/method/subroutine/... that given a list of angles in degrees returns their mean angle. ... Use the function to compute the means of these lists of angles (in degrees): [350, 10] [90, 180, 270, 360] [10, 20, 30] Show your output here.
mean = median = mode symmetry about the center 50% of values less than the mean and 50% greater than the mean
While many projects can be worked on either a vertical or horizontal mill, each type can offer unique advantages for certain milling specifications. Vertical milling is an excellent choice for projects mostly worked on a single side, such as sinking dies and working with large metal plates.
