Question

Select the correct option from the following statements about the physical properties of silk.

• A. Silk rope is stronger than metal wire of similar dimension
• B. Silk rope is stronger than metal wire of any dimension
• C. Silk rope is heavier than metal wire of similar dimension
• D. Silk rope is more rigid than a metal wire of similar dimension

Answer 1

The correct option is A

Silk rope is stronger than metal wire of similar dimension

Silk rope is stronger than metal wire of comparable dimension. If an experiment is done, in which different weights are tied to different ropes of silk, cotton, wool and metal, then it is observed that silk can bear the maximum weight implying it is stronger than the rest of the materials used. But the density of silk is lesser than metal, so it weighs less than metal wire. Also, silk is more flexible when compared to a metal wire.
