Steel is more elastic than rubber because it :
A. Requires larger deforming force
B. Is never deformed
C. Is deformed very easily
D. Is harder than rubber
Answer: Option A
Solution(By Examveda Team)
The elasticity of a material is determined by its ability to return to its original shape after being deformed. Steel, being a metal, has a high modulus of elasticity and requires a larger deforming force to change its shape, but it also has the ability to return to its original shape once the force is removed. Rubber, on the other hand, is a polymer with a lower modulus of elasticity, meaning it is easily deformed and doesn't return to its original shape as effectively as steel.This Question Belongs to General Knowledge >> Physics
