Abstract
Within an experimental error of ∼0.3% the static and the dynamic torsion constants of selected small tungsten wires are equal. It is suggested that spurious forces which have been observed in torsion Knudsen effusion recoil measurements arise from thermomolecular flow rather than from torsionally anisotropic wires.This publication has 6 references indexed in Scilit:
