LMEC-21 Vibrating String Experiment(chingwe chomveka mita)

Kufotokozera Kwachidule:

LMEC-21 imagwiritsa ntchito chingwe chachitsulo ndi oscilloscope kuyeza mafunde oyimirira ndi kugwedezeka kwa chingwe chofanana, ndipo imatha kukulitsa kuyesa kwatsopano, chida ichi chimafunikira oscilloscope yokonzekera yokha.
LMEC-21A ndi mtundu wotsika mtengo womwe sufuna oscilloscope, Cholinga cha chida ndikukhazikitsa zoyeserera zamawu osangalatsa. Sizingangoyesa zoyeserera zachikhalidwe za zingwe zogwedezeka, komanso kukulitsa kuyeserera komwe kumagwiritsidwa ntchito kuti athe kuwongolera kamvekedwe ka zida za zingwe ndikuphunzira mfundo zogwirira ntchito za zida za zingwe.

Kuyesera Kwakukulu
1. Ubale pakati pa kutalika kwa chingwe, kachulukidwe kakang'ono, kukangana ndi kuima kwa mafunde kumaphunziridwa;
2. Kuthamanga kwa mafunde kumayesedwa pamene chingwe chikugwedezeka;
3. Kufufuza: mgwirizano pakati pa kugwedezeka ndi phokoso; 4. Kuyesa kwatsopano ndi kafukufuku: Kafukufuku wokhudza kusinthika kwamakina amagetsi pamakina ogwedezeka.
