Abstract
The effective mass or moment of inertia of an object in a liquid may be considerably greater than the corresponding value in vacuum. Hence many applied dynamical problems require the use of effective rather than actual values. Herein is reported an experimental method, making use of a torsion pendulum, for determining the increase or ``virtual'' moment of inertia or mass of an object due to a surrounding liquid. Actual data on disks and cylinders in water, gasoline and carbon tetrachloride are given. Experimental and theoretical results are compared where possible.This publication has 0 references indexed in Scilit:
