Specific Strength Of Materials Is Very High When They Are In Fibre Size But Lower When They Are In Bar Form - Why? |
|
Answer» The crystal structure has ordered, repeating arrangement of atoms. Fibers are LIABLE to maintain this and thus have HIGH specific STRENGTH. As for size increases, the CONDITION of ordered and repeating arrangements can’t be guaranteed because of several types of defects and dislocations, and thus the specific strength GETS lower.
