Measuring the force components on an object simultaneously is one of the problems encountered in engineering. The design of a measurement system that can simultaneously measure such forces, as well as its working principles, production stages and application of this system in a wind tunnel are presented. The system consists of an arm to which the model is attached, a five-bar mechanism, and load cells that measure horizontal and vertical forces. The signals obtained from the load cells are amplified and transferred to a computer. Manufacture of the parts, assembly and calibration of the system are explained. An application of the measurement system was carried out in a wind tunnel and the results are presented.
