Question

The length to height ratio of a closed filled arrow head is?

(a) 1:3

(b) 3:1

(c) 1:2

(d) 2:1

This question was posed to me in my homework.

My doubt stems from Lines, Lettering and Dimensioning topic in chapter Lettering Practice, Scales & Curves of Civil Engineering Drawing

Answer 1

Right choice is (b) 3:1

For explanation I would say: This  arrow is called as closed filled arrow head as it is hatched and closed. Due to bold appearance and hence good visibility and uniform ratio makes it a good arrow for use.
