consider a two dimensional stress system, in which body is subjected to stress 1 and 2 in x and y directions respectively, then the total strain in x direction is equal to?

A) = (longitudinal stress in x direction + lateral strain in y direction) B) =(longitudinal stress in x direction - lateral strain in y direction) C) =(longitudinal stress in x direction - lateral strain in x direction) D) =(longitudinal stress in x direction + lateral strain in x direction)
