The grand averageelves the result that the unit deformation in the line of actionof the greater load at the portion of the test piece subject totwo perpendicular compressions, one compression half as greatas the other, is of the unit deformation on the arm underthe greater compression. Assuming, as in the case of comparisonbetvreen compression specimens stressed in only one directionand compression specimens stressed equally in tiro directions,that the effect of the enlarged section is the same v;hen tT70stresses are present as when only one is present, ne get theresult that the presence of the smaller compression reducesthe unit deformation on the cross, measured in the direction ofthe greater compression, to or of the unitdeformation on the arra under the greater load.
