uction is relatively large so that from10 to 100 feet will be represented by an inch, for it has di-visions of lOths, 20ths, 30ths, 40ths, and 50ths, of an inch.It can also be used in the same way as the mechanical en-gineers scale. To illustrate: The twentieths scale canbe used for J inch to the… … Curves and Straight Lines Combined, and Sections 67 equalling one inch. By thus assigning arbitrary values tothe divisions, any ordinary mechanical engineers require-ments can be fulfilled with the trouble only of interpolationfor some of the smaller measurements. 23.
