The balance consists of the triangle platform connected to the rotating frame through the rods and pivot flexures. A wind tunnel model is connected to the triangle platform by two support struts: the main support strut and the tail support strut.
An optimized way of using 6 Load cell, which in turn uses change in resistance due to elongation which is measured in terms of voltage across that, can be recalibrated to the force applied. A set of forces at a distance causes couple thus even moments can be measured.
