Identify the incorrect statement....

Identify the incorrect statement.

A

Youngs modulus and shear modulus are relevant only for solids

B

Bulk modulus is relevant for solids, liquids and gases

C

Alloys have larger values of Young's modulus than metals

D

Metals have larger values of Young's modulus than elastomers

Text Solution

Verified by Experts

The correct Answer is:
c
Because the alloys have high density, they have larger values of Young's modulus then metals.
