This Report deals with the variation of percentage of elongation with different gauge lengths and sections of test bar. It is based almost entirely on tests of steel plate test bars supplied by Mr.ColviDe, of the Dalzell Steel Works, Motherwell, N.B., and by Mr. Dick, of the Parkgate Steel Works. These tests cover a wide range of conditions, and no such complete information as to variation of elongation with the form of test bar has been previously available. As the results are, it is believed, valuable, whatever decision may be x5 arrived at as to standard forms of test bars, the results have been very fully and critically discussed.
