Question

Little sonu wants a ride on a parachute. His father checked the ropes of the parachute and confirmed it is made of nylon. Why can't we use rayon here?

Answer 1

Nylon replaced when silk world war 2 is diminished. Nylon has resistance to wind and has good elasticity and are also cheaper. Rayon does not have all of these properties.

That's why when little sonu wants a ride on a parachute, his father checked the ropes of the parachute and confirmed it is made of nylon.
