1.2 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)
Figure 1.21 – The examples of slope.
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
The Taper State Standard 8593-81
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).
