Question

5. Anuj has performed an experiment to compare
the strength of different fibres. He arranged the
set-up as shown in figure: Arrange the threads
in order of their increasing strength.
Hook
Threads of same
length and thickness
were taken
Weights were put
one by one till the
thread broke
(a) Nylon < Silk < Cotton
(b) Silk < Cotton < Nylon
(c) Cotton < Nylon < Silk
(d) Cotton Silk < Nylon​

Answer 1

The correct order will be Nylon> Silk > Cotton.

• Nylon lies in the category of synthetic fibres due to which it is the strongest of all. It is specially designed to bear a lot of stress before breaking, because of which it is used in ropes, etc.
• Then next comes silk which has a little less ability of forming long chains as compared to Nylon due to which it comes in second position.
• While cotton is the last one because it cannot form long chains therefore it breaks off easily.
