Question: Which of the following is the correct relation? $ Y= $ Young’s modulus & $ G= $ modulus of rigidity?

Options:

A) $ Y<G $

B) $ Y>G $

C) $ Y=G $

D) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

[b] Young’s modulus $ Y=2G(1-\sigma ) $

$ G= $ modulus of rigidity and $ \sigma = $ poissons’s ratio
