If we assume that the relation of the enlarge^l section atthe cross to the reduction in the unit deformation on the crocsis the same when a specimen is tested under one load as when itis tested under two equal loads, we can deduce a relation betweenthe unit deformation of any specimen loaded in tv;o directionswith equal loads and the unit deformation which would occur ifthe same specimen were loaded with one of these same loads, asfollows: From the average of all specimens loaded with two equalcompressions we have that the unit deformation at the center ofthe specimen is 0,66 of the deformation on the arm, and from theaverage of all specimens tested with one compression, we have(Table VIII) that the
