FIELD: education. SUBSTANCE: device comprises vessel 1 filled with fluid 2 and body 3 positioned inside the space of vessel 1 and made up as hemisphere. The outer side of the body is provided with a number of screw grooves 4 or projections. Weights for varying the depth of submersion of the body are mounted inside body 3 on area 6. In the initial position there is no energy supply to the fluid, but under the action of fluid 2 that exerts on inclined surfaces of screw grooves 4 or projections 3, the body begins to rotate in the fluid about the vertical axis. EFFECT: expanded capabilities. 2 cl, 2 dwg |
