Mechanics experimental instrument of rotation paraboloid

The invention discloses a mechanics experimental instrument of rotation paraboloids. The mechanics experimental instrument is used for mechanical rule demonstration for the rotation paraboloids in or after class. Three silvery smooth metal rings of the same material and size sleeve three parabolas made of metal wires respectively and are combined with a motor, so that the stability of objects on the rotation paraboloids is demonstrated, and rules of a liquid differential element in a rotation liquid surface are researched. Compared with the prior art, the experimental instrument has the advantages that f the three metal wire parabolas of different colors are driven by the motor and stable in the rotation speeds, mechanics stability effects of the three metal rings in the three rotation paraboloids can be seen simultaneously, mechanical rules of the liquid differential element in the rotation liquid surface are effectively indirectly demonstrated, and the experimental instrument, as an instrument of demonstrat
