SOME GEOMETRICAL CONSTRUCTIONS

The Slope State Standard 8908 – 81

The slope characterizes inclination of one line or a plane according to the other (fig.1.21)

To mark the slope on a drawing a sign or is put before a size number, where Н is a font size. Slope examples are shown on figure 1.22.

	Figure 1.22 – The examples of slope

A taper is defined as unit alteration in a specified length measured along the axis in case of a shaft and a base line or a center line in case of flat pieces as shown in Fig. 1.23.

The taper is the correlation of difference of diameters of two cone cross-sections toward distance between them (fig.1.23).

	Figure 1.23 – The calculation of taper

To mark the taper on a drawing a sign or is used which is put before a dimension (fig.1.24).
