Q1: Justify how young’s modulus of material is considered as important for materials

Write by microsoft word ( text )

Answer 1

◆ There are some characteristics of young's modulus which make it an important property for any material :-

• Young's modulus measures the resistance of a material to elastic (recoverable) deformation under load.

• A stiff material has a high Young's modulus and changes its shape only slightly under elastic loads (e.g. diamond). A flexible material has a low Young's modulus and changes its shape considerably (e.g. rubber)

• A stiff material requires high loads to elastically deform it - not to be confused with a strong material, which requires high loads to permanently deform (or break) it.

• The stiffness of a component means how much it deflects under a given load. This depends on the Young's modulus of the material, but also on how it is loaded (tension, or bending) and the shape and size of the component.

• Specific stiffness is Young's modulus divided by density (but should more properly be called "specific modulus").

So above given characteristics of the young's modulus makes it important for any material.

if helpful them give ?.

thank you.
