As the methods of measuring Young's Modulas E, ordinarily the so-called static measuring methods, for example, tension test or bending test is used. But in practice, the stresses applied to the materials which constitute machines or structures are scarcely pure static but nearly dynamical. Then I devised and designed newly a measuring apparatus for E by the transverse vibration of cantilever, and made an experiment on several drawn metal wires at room temperature. I observed the relation of E with the annealing temperatures, the carbon percentages and the diameters. Moreover, I compared the static tension test results with the newly devised dynamical test results.
