I think x is any distance along the beam where strain can occur under a considerable amount of stress. hence, the modulus of elasticity is applicable here. Also, L/2 is where ultimate failure is likely to occur and hence it is where the plastic hinge is located, hence, the plastic modulus is applicable here and that is the idea of having the ratio as 0.5L/X=1.5.
Therefore X=0.33333333L=L/3.
Therefore X=0.33333333L=L/3.

Can we call the ratio between plastic moment to elastic moment as the ELASTOPLASTIC zone?
