Poission's ratio is ratio of mcq



Poission's ratio is ratio of .......


A) Lateral stress ÷ linear stress

B) Lateral strain ÷ Linear strain

C) Linear strain ÷ Lateral strain

D) Lateral strain × Linear strain 

Correct answer : option B ( solution discussed below)


The poission's ratio is defined as it's a ratio of lateral strain per unit linear strain.

Poission's ratio 
         = Lateral strain 
             Linear strain 

poission ratio is a unit less quantity (no unit)
