Stabilized-platform weighing scale of novel design. . ghest elasticitymay be sacrificed for endurance in humid or acid atmospheres, inwhich case any of the strong and elastic bronzes will serve tapes, of thickness from inch up and of various widths,are available commercially at low cost. Knife-Edge Reactions Inclined.—It will be seen in Fig. 17 thatthe load and fulcrum knife-edges are somewhat inclined towardthe quadrant opposite the platform, the purpose of this -being toapproximate the mean position of the reactions at these knife-edges so that the scale will be as nearly as possible immune againstslipping of the knife-edge on its bearing in a direction perpendicularto the line of the pivot. No rational method can be given for thechoice of the angle of inclination of the knife-edge, since thedetermination of the most favorable angle will depend upon themanner of weighing and the bulk of the material weighed; but it ishardly to be recommended that the knife-edge be inclined in the Stabilized-Platform Weighing Scale 17.
