Abstract : A novel design of a two-point attachment apparatus for measuring normal and tangential drag coefficients of a flexible wire conduit is presented. A technique is developed to stiffen the flexible cable so that its catenary is reduced. An instrumentation method that accurately measures the desired inline forces is also presented. The fundamental frequencies of vibration are calculated for the drag apparatus and compared with the expected excitation forces.... Hydrodynamics, Drag coefficients, Drag forces, Mechanical cables.
