it is ok
But i cannot possibly remember values for al and cu
Isnt there any time saving method.
this is a past year jee question?
Most of the commercially used metals have poissons ratio less than 0.3 . If they ask ,you can take a reasonable value between 0.2-0.3 as the poissons ratio of metals and 0.4- 0.5 for polymers.
