Question

For a plain scale, RF = \(\frac{1}{4}\) and M.L = 5decimeters, what is LOS?

(a) 1.25 cm

(b) 12.5 cm

(c) 12.5 m

(d) 12.5dm

I got this question in my homework.

My doubt is from Scales in section Lettering Practice, Scales & Curves of Civil Engineering Drawing

Answer 1

Right option is (b) 12.5 cm

The best I can explain: LOS = R.F*M.L = \(\frac{1}{4}\)*5 *10 cm (Since 1dm = 10 cm)

                                  = 12.5 cm.
