LMEC-21 Vibrating String Experiment(tambo yekurira mita)

Tsanangudzo Pfupi:

LMEC-21 inoshandisa tambo yesimbi uye oscilloscope kuyera kumira kwakamira uye kuzunguzika kwetambo yakafanana, uye inogona kuwedzera kuyedza hunyanzvi, chiridzwa ichi chinoda yakazvigadzirira oscilloscope.
LMEC-21A ishanduro yakachipa isingade oscilloscope, Chinangwa chechiridzwa ndechekumisa inonakidza tambo yekurira kuyedza. Haikwanise kungoita zvechinyakare tambo vibration kuyedza, asi zvakare kuwedzera kune yakashandiswa kuyedza kugadzirisa matauriro ezviridzwa zvetambo uye kudzidza musimboti wekushanda wezviridzwa zvetambo.

Main Experiments
1. Hukama huri pakati petambo kureba, mutsara density, tension uye kumira wave frequency inodzidzwa;
2. Mafambiro ekufambisa kwemafungu anoyerwa kana tambo ichizunguzika;
3. Kuedza kubvunzurudza: hukama huri pakati pekudengenyeka uye inzwi; 4. Innovation uye tsvakurudzo yekuedza: Tsvakurudzo pamusoro pemagetsi ekugadzirisa kushandura zvakanaka kwekumira wave vibration system.
