The block split into four approximately equal larger pieces and four smaller but still significant smaller pieces. there was minimal fines and small fraction produced. the throw on this blast was much greater than on any of the previous blasts, with large fragments landing up to 8.4 m away. one fragment from the blast is shown in figure.The convex surface is under tension, as in an ordinary beam test. (see fig. 6.) if the same stick is braced in such a way that flexure is prevented, its supporting strength is increased enormously, since the compressive stress acts uniformly over the section, and failure is by crushing or.
