Abstract
Strain gaure–based electromechanical force transducers, strain gauge technical requirements, as well as arrangements and connections of strain gauges for measuring loads have been presented. Calculations of many different strain gauge–based electromechanical force transducers and their application in wind tunnel tests are also described.

Key words: aerodynamic forces, electromechanical forces, force transducers, electromechanicaltransducers, force measurement, measurement of stress, measurement of strain, strain gauge, aerodynamic test, wind tunnel.
