Turbulent boundary layer on a body of revolution under influence of eddy breakup devices

An improved load cell comprises flexing elements and support structure connected thereto by welding. Each flexing element has enlarged end portions, extending through openings in the support structure, and an intermediate flexing portion extending between the support structures. The enlarged end portions are welded to the end plates by electron beam welding so that the stress and strain characteristics of the intermediate flexing portions, between the end plates, are not modified from their pre-welded state.
