Apparatus for displaying centrifugal force action

The utility model relates to a device which can show centrifugal force role, which is characterized in that the device comprises a base, an operation part and a display part. The inner of the base is provided with a fixing frame, a pair of bevel gears and a speed shifting mechanism are arranged on the fixing frame, the speed shifting mechanism is an accelerator, wherein the output end is connected with a pair of bevel gears whose output end is connected with a transmission shaft, one end of the transmission shaft is connected with a generator, other end extends into the display part. The operation part is a shaken handle, the inner end of the shaken handle is connected with the speed shifting mechanism. The display part comprises a transparent cover, a pair of fixed seat and at least a bouquet of elastic steel strip. One of a pair of fixed seat is fixedly arranged on top of the transmission shaft which extends into the transparent cover, other is sleeved on the transmission shaft. At least one bouquet of elastic steel strip is arranged between two fixed seats. When the visitor shakes the handle, the elastic steel strip beam is driven to rotate by the rotary mechanism; the two ends of the steel strip beam are acted on by the centrifugal force to form a variation of ellipse, the greater the speed is, the larger the centrifugal force is, and the flatter the ellipse is. The device shows the effect of the centrifugal force from the mechanics and the optics.
