These separate are numbered 2055-A, 2055-B, 205G-A, 205G-B, 2057-A,2057-B, 2058-A and 2058-B. The S-in. cubes vrere made in pairsin steel forms, Por studyir^G the effect of tvTO bending stresses, crossedbeams Txere made. A crossed beam consists of two simple beams12 in. 7/ide, 10- in. deep to the center of the steel, and 7 ft.,5 in. long over all, crossing at their centers.
