Question

For a light weight and fine fabric you require 1
a) single strand yarn
b) ply yarn
c) cord yarn
d) any yarn

Answer 1

Answer:

A single strand yarn is the right answer.  

Explanation:

It is composed of 'concentric simple helices' with equal pitch. The fiber of helices are perfectly 'elastic thin rods' and the yarn is ready to be a 'conservative system'.  

The 'fibers' are in two states; which is a 'jammed and free state.'  

When a 'fiber' is in the 'jammed state', its 'radial movement is restricted.' When a 'fiber' is in the 'freely moving state', its 'neighboring fibers' do not have any 'interaction' with it.  

It will find an 'equilibrium state' which is subject to the rule which remains to 'helical' at the 'prescribed pitch' and 'zero tensile strain'.
