A method of studying virtual mass of plates and discs in linear-accelerated motion involves: (1) simple apparatus for strobophotographic recording of small displacements at the rate of 500 per sec within a test interval of 1/25 sec under the same initial force; and (2) analysis of data form wet and dry tests plotted on a trilinear chart with displacement as ordinate, mass as abscissa, and time intervals as parameter. Variability of data is reported. Reference is made to a comprehensive bibliography on virtual mass studies.
