| 摘 要： | In as paper,an eddy current analogy and a brief sketch of required equipment arepresented.Values of torsional rigidity and shearing stresses of a prismatic bar under freetorsion can be obtained experimentally to a high degree of accuraey in an instant with thisequipment whether the cross-section is bounded by a single boundary or multi-connectedboundaries.The error is les than two per cent generally,as shown in Table 3.This newanalogy can be used extensively to solve various physical problems expressed by Poisson’s(or Laplace’s) equation with constant boundary condition.
