Abstract
A load cell which may be embodied in an arch beam structure or a shear tension link and comprising a flexure area design which requires the machining of only five parallel holes. The five holes comprise a large central hole and four satellite holes to define two opposite load paths, each including two flexure areas which react to a load in opposite tension-compression sense. Strain gage resistors of the foil type are bonded onto the flexure areas and connected into a Wheatstone bridge circuit.
