Liwiro la kufalikira kwa mafunde likhoza kudziwika pogwiritsa ntchito njira yonseyi:
Kufotokozera kwa fomula:
v = liwiro la kufalikira kwa mafunde (mayunitsi ndi mamita/sekondi)
T = nthawi ya mafunde = nthawi yomwe mafunde amafunikira kuti ayende mu wavelength imodzi (mayunitsi ndi masekondi)
f = pafupipafupi = chiwerengero cha mafunde omwe amadutsa mfundo yomweyo pa sekondi imodzi (gawo ndi 1 / sekondi = hertz)
lambda = kutalika kwa nthawi (mayunitsi ndi mamita)
Kodi fomula yomwe ili pamwambayi imachokera kuti? Mwina mukukumbukira fomula ya liwiro v = s / t, pomwe v = liwiro, s = mtunda woyenda, ndi t = nthawi yopuma. Iyi ndi fomula ya liwiro la chinthu, monga momwe taphunzirira pankhani yoyenda molunjika.
Ngati yasinthidwa kuti igwirizane ndi kayendedwe ka mafunde, mtunda womwe umayenda umakhala wofanana ndi kutalika kwa mafunde, nthawi yomwe imayenda imakhala yofanana ndi nthawi (T = 1/f) kapena pafupipafupi (f = 1/T).
Liwiro la kufalikira kwa mafunde pa chingwe
Mafunde omwe amafalikira pa zingwe kapena zingwe ndi mafunde opingasa, owerengedwa pogwiritsa ntchito njira iyi:
Kufotokozera kwa fomula:
v = liwiro la mafunde pa chingwe (mayunitsi ndi mamita/sekondi)
F = mphamvu yogwira chingwe (mayunitsi kg m/s2 (wotchedwanso Newton)
Myu = kulemera kwa chingwe = kulemera pa unit kutalika kwa chingwe (mayunitsi ndi ma kilogalamu/mita)
Kutengera ndi fomula yomwe ili pamwambapa, zatsimikiziridwa kuti liwiro la mafunde pa chingwe limadalira mphamvu ya chingwe ndi kulemera kwa unit iliyonse ya chingwe. Momwe fomula iyi imapezekera ingadziwike potengera njira yopangira. liwiro la kufalikira kwa mafunde pa chingwe.
Liwiro la mafunde a phokoso
Mafunde a mawu ndi mafunde aatali omwe amafalikira kudzera m'njira zosiyanasiyana. Pali njira zambiri zomwe mafunde a mawu amatha kudutsamo, kuphatikizapo mpweya, madzi, makoma, ndi zina zotero. Liwiro la kufalikira kwa mafunde a mawu limadalira makhalidwe a njira yomwe amadutsamo, monga momwe liwiro la kufalikira kwa mafunde opingasa mu chingwe limadalira makhalidwe a chingwe.
Ngati mafunde a phokoso akuyenda kudzera mumadzimadzi monga mpweya kapena madzi, liwiro la phokoso limawerengedwa pogwiritsa ntchito fomula
Kufotokozera kwa fomula:
v = liwiro la mafunde a phokoso
B = kuchuluka kwa modulus
rho = kuchulukana
Ngati mafunde a phokoso afalikira kudzera mu ndodo yayitali komanso yolimba, liwiro la phokoso limawerengedwa pogwiritsa ntchito fomula
Kufotokozera kwa fomula:
Y = Modulus ya Young
Liwiro la mafunde amagetsi
Liwiro la mafunde amagetsi (liwiro la mafunde a kuwala) ndi 3,00 x 108 Ms.
Liwiro la kufalikira kwa mafunde pa chingwe
Zinthu zomwe zimakhudza liwiro la mafunde opingasa mu zingwe
Liwiro la mafunde amakina limadalira kokha pa makhalidwe a chinthu chomwe chimayendamo. Liwiro la mafunde a m'nyanja limadalira mtundu wa nyanja, liwiro la mafunde a phokoso limadalira mtundu wa mpweya womwe amadutsamo. Momwemonso, liwiro la mafunde mu chingwe limadalira makhalidwe a chingwe. Kuti mumvetse bwino izi, choyamba chitani kafukufuku wofufuza zinthu zomwe zimakhudza liwiro la mafunde mu chingwe.
Kutengera ndi zoyeserera zomwe zidachitika, zidatsimikizika kuti liwiro la mafunde pa chingwe limadalira mphamvu ya mafunde pa chingwe ndi kulemera kwa unit iliyonse ya chingwecho. Mphamvu ya mafunde ikakula (chingwe chikakhala cholimba kwambiri), mafunde amasuntha mofulumira. Mosiyana ndi zimenezi, kulemera kwa chingwe kukakhala kwakukulu, mafunde amasuntha pang'onopang'ono.
Kuchokera kwa fomula ya liwiro la mafunde opingasa mu zingwe
Kuchokera kwa njira ya liwiro la mafunde pa zingwe ndi umboni wa masamu wa zinthu zomwe zimakhudza liwiro la kufalikira kwa mafunde pa zingwe.
Taganizirani za chivundikiro cha mafunde kapena kugunda kwa mtima komwe kumayenda kumanja kudzera mu chingwe (chithunzi chapamwamba). Chithunzi cha kugunda kwa mtima chikukulitsidwa, limodzi ndi chithunzi cha mphamvu ya mphamvu ya chingwe F yomwe ikugwira ntchito pa chingwe chomwe chimadutsa pamwamba pa mafunde (chithunzi cha pansi).
Mphamvu iliyonse yolumikizira chingwe (F) imafotokozedwa mopingasa (F)x) ndi njira yolunjika (FyMphamvu zonse ziwiri Fx ali ndi kukula kofanana komanso mbali zosiyana kotero amaletsana. M'malo mwake pali mphamvu ziwiri za Fy kupita pakati pa bwalo.
Kukula kwa mphamvu iliyonse kumbali yolunjika (F)y):
Mphamvu yochokera pakati pa bwalo
Msonkhano wa zingwe
Lamulo lachiwiri la Newton la kuyenda kozungulira kofanana
Kufotokozera kwa fomula:
v = liwiro la mafunde pa chingwe (m/s)
F = mphamvu ya kukangana kwa zingwe (Newton)
myu = kuchuluka kwa chingwe = kulemera pa unit kutalika kwa chingwe (kg/m)
Kutengera ndi equation yomwe ili pamwambapa, zitha kuganiziridwa kuti liwiro la mafunde limagwirizana ndi mphamvu ya chingwe ndipo limagwirizana molakwika ndi kulemera kwa chingwe pa unit. Chifukwa chake, chingwe chikakhala cholimba, mafunde amathamanga kwambiri, komanso kulemera kwa chingwe kukakhala kwakukulu, mafunde amachepa pang'onopang'ono.
