As the causes of the dispersions in the measurements with a balance, we considered the roughnesses of the knife edge and the flat bearing. About this problem, we made a thorough research on various knife edges, and as a result the following formula was found. σΔW=W/L·α·b where σΔW is the standard deviation of dispersions, W is the load supported by the knife edge, L is the distance between center and end knife edge, α is a constant, b is the breadth calculated by Hertz's equation. However, the roughness of the knife edge, and the flat bearing treated in our preceding reports, was nearly constant, consequently α was nearly constant, α must be the function of the roughness, so we changed this time the roughness of the flat bearings in a wide range, and observed σΔW. We found two essential sources of the dispersions as well as the quantitative relations between them.
