Abstract

Przedmiotem zgłoszenia jest przyrząd do badania siły odśrodkowej i siły wyporu, mający zastosowanie w laboratoriach fizycznych. Przyrząd do badania siły odśrodkowej i siły wyporu zawiera podstawę (1) w kształcie poziomej płyty, zaopatrzonej w pobliżu brzegów w kołek (2) ze stożkowym końcem dolnym oraz dwie śruby (3, 4), wkręcane w płytę i mające również stożkowe końce dolne, ponadto z płytą połączony jest pionowy wspornik (5), do którego został przymocowany silnik elektryczny prądu stałego (6), przyłączony do zasilacza. Oś silnika jest ustawiona pionowo i została na niej osadzona tarcza (8) ze znacznikiem, obok której znajduje się elektroniczny wskaźnik szybkości obrotów. Powyżej tarczy na osi silnika osadzona jest też prostokątna ramka (11) z poziomą poprzeczką, w którą wkręcana jest od dołu śruba (13) z radełkowanym łbem, zaopatrzona w nakrętkę kontrującą (14), dokręcaną do poprzeczki. Górny koniec śruby (13) połączony jest z płytą oporową (15) z przyklejonym do niej od góry magnesem walcowym (16), namagnesowanym w kierunku osiowym. Oprócz tego do górnego boku ramki (11) przymocowana jest symetrycznie przezroczysta rurka (17) w kształcie litery V z odgiętymi pionowo górnymi końcami ramion (19), zamkniętymi korkami gumowymi (20). Przezroczysta rurka (17) wypełniona jest cieczą (22), w której zanurzone są kulki (23).The subject of the application is a device for testing centrifugal force and buoyancy force, applicable in physical laboratories. The centrifugal force and buoyancy force testing device includes a base (1) in the shape of a horizontal plate, provided near the edges with a pin (2) with a tapered bottom end and two screws (3, 4), screwed into the plate and also having tapered bottom ends, in addition, a vertical bracket (5) is connected to the plate, to which a DC electric motor (6) has been attached, connected to the power supply. The motor axis is vertical and a disc (8) with a marker is mounted on it, next to which is the electronic speed indicator. Above the disc, on the motor axis, there is also a rectangular frame (11) with a horizontal crossbar, into which a screw (13) with a knurled head is screwed in, provided with a counter nut (14), tightened to the crossbar. The upper end of the screw (13) is connected to the thrust plate (15) with a cylindrical magnet (16) glued to it from above, magnetized in the axial direction. In addition, a symmetrically transparent V-shaped tube (17) with vertically bent upper ends of the arms (19), closed with rubber plugs (20) is attached to the upper side of the frame (11). The transparent tube (17) is filled with liquid (22) in which the balls (23) are immersed.
