FIELD: experimental study of resistance force of medium to motion of bodies. SUBSTANCE: stand includes rigidly secured vertical guide for orientation of body under test in space and measuring device (dynamometer). According to first version, stand includes reservoir filled with sand. Measuring device is placed in lower part of stand at level of position of body under test and reference body in reservoir. According to second version, stand includes reservoir for medium and body under test; lower portion of reservoir contains sand. Measuring device is placed at level of position of reservoir. EFFECT: reduced consumption of labor; enhanced accuracy and reliability in determination of resistance force; extended functional capabilities. 3 cl, 2 dwg
