The elastic properties of concrete under bi-axial loading . spring dynamometer called dynamometer ITo. 1, and shOTmIn operation inPig. 7 and 8. The dynamometers used in measuring the load on a specimenin some of the tests reported in this discussion resembleRegniers dj-namometer, vvhich is an elliptical spring whose colla-in the direction of its minor axis is made to move an indexfinger on a graduated arc. See Fig. 12, page 43. They consistessentially of two beams loaded at t-O points, with tOY^ard each other, and separated by steel bloclcs. dial is placed betv^een the two beams and measures theircombined flexural deflections, which is a measure of the appliedload. The beams are rectangular, by 2-in. in crosssection, 19-in. long and are made of niclcel steel. The bloclcsat the ends of the beams are 5 x 2 x and are of thesame material. Two 3/4-in. bolts through the ends of the beamshold the instrument together and when firmly tightened provide aslight restraint at the ends of the beams. The Mies dial reads. 9 Fi3 12.
