Sir can we say that if a material is stiff that means there is negligible elastic strain in the material but if a material is elastic then there is elastic strain in material which is fully recoverable upon unloading of material....
So basically is Young's Modulus is high, that means it's Stiffness is high as we need very high stress to produce a definite elastic strain inside the specimen and since the Young's Modulus (E) is high, it's elasticity is high too... Because E for Aluminum = 70 GPa and E for Steel = 210 GPa, thus E (steel) > E(Aluminum) and hence we say Steel is more elastic than aluminum..Correct explanation???

Stiffness is Ability of a material to resist elastic deformation.
@@shettyrajeshwar7408 that i know but is my explanation regarding the elasticity comparison of Steel and Aluminium above is correct or not?😊
@@kabeerdixit9364 Yes it is crct whatever u said about elasticity comparison.
Thanks

The student is so dull & confusing.....
