DEVICE FOR STUDYING LAWS OF ROTARY MOVEMENT Russian patent published in 2007 - IPC G09B23/06 

FIELD: training appliances.

SUBSTANCE: device for studying laws of rotary movement comprising a base, on which a frame is held by a post, with wire held on it made with possible change of speed of rotation and comprising an electric motor, on output end of which a pulley is held, and a body, in which an axis is installed with possible rotation, on console end of which stroboscope and disk pulley are serially mounted, the latter interacting with the pulley of electric motor, and stroboscope interacts with the sensor installed on the free end of post and fitted with detachable cable for connection to control block. Quadrilateral working frame is held on disk pulley with suspensions, pendulum, or suspension provided with signal element positioned in the frame, console end of the suspension by means of brackets interacts with a spring with holder and dynamometer, or with trap and cone with curved end, or with flat vat containing colored liquid.

EFFECT: creation of universal device, which allows studying of rotary movement and various oscillations, modeling of Stern experiments, studying of liquid rotation and Doppler effect.
