There are many papers on scales, but they all assume that the scale is lying on the horizontal plane at rest, and existing scales are all designed on that assumption.
Because of the increasing number of large fishing vessels containing plants for dressing fish, the demand for shipboard scales which can be used on a moving base is increasing.
The authors intended to make a shipboard scale and have found two ways to make it. One is the way in which
(1) one reads the difference of the two angles of deviation of two independent levers which swing in the same way when the base swings.
The other is the way in which
(2) one constructs compound levers which are connected so as to cancel the influence of the motion of the base.
A product based on case (1) will be manufactured shortly. The authors explain the theory of the simple lever which is fixed on a moving base, introduce experimental data, and show the usefulness of the first way in this paper. They will be publishing the details for case (2) following this explanation of case (1).
