Ako i te tautau - me pehea ki te kitea te wā o te oscillation tāwēwē ohie

Ko te momo o te tukanga oscillatory e haati nei ia tatou, kia nui ai he poitirere - a reira he tahi mea e kore e kapewhiti? Whakauaua, mai ara ahanoa rawa aueue ore, e mea he kohatu, i te mea mano o nga tau ko tonu, tonu oscillates tukanga - wā pupū ake i roto i te ra, te whakanui ake, a i te po mātao me Tīngongo. Na te tauira tata - rakau me manga - e kopikopiko ana kaha katoa tona ora. Ko reira -, kohatu rakau. A, ki te koutou hau tika awhe pēhanga i 100 whare kōrero? Kei te mohiotia te reira, mo te tauira, e te runga pourewa Ostankinskaya e whakakotititia ana te hoki a mai i 5-12 mita, pai atu i kore tāwēwē 500 m tiketike. A tae noa ki te piki i roto i te rahi hanga rite i ngā rerekētanga pāmahana? Tenei ko reira taea ki te whakarōpū me te wiri o mihini me pūhanga pourewa. whakaaro tika, te manureva i roto i nei rere koutou tonu rerekē. Kaua e huri tō whakaaro ki te rere? Ehara i te mea e tika ana, no te mea te rerekē - ko te uho o te ao huri noa ia tatou, e kore e taea e matou te maka o ratou - e taea anake te tangohia e ratou ki pūkete, me te tono i te "pai mo".

Ka rite ki mua, te ako o te wāhanga tino matatini o te matauranga (a ratou tika e kore e tupu) haamata ki te whakataki ki te tauira ohie. Na reira ko te ohie me atu mahino ki te tauira perception o te tukanga oscillatory, atu i te tautau. Ko konei te reira i, i roto i te ako o te ahupūngao, tatou te tuatahi whakarongo ki tenei parau ngaro - ". wā o oscillation o te tāwēwē ohie" Tautau - Ko te miro, me te kawenga. A he aha te mea he tāwēwē motuhake tenei taua - Pāngarau? He tino māmā, kei te tūmanako tenei tāwēwē e kore e te miro i te taimaha o te whakawhānui-kore, me te wāhi rauemi pāoro i raro i te mana o te mahara. Ko te meka ko e te tikanga, whakaaro he tukanga, hei tauira, te wiri taea kore e pūkete tino tonu o ngā āhuatanga tinana pērā i taimaha, elasticity, me ētahi atu kaiuru katoa i roto i te whakamātautau. I te wa ano, he hokiate te mana o etahi o ratou i roto i te tukanga. Hei tauira, he priori kua matau ai e te taimaha tautau me elasticity miro i raro i etahi tikanga i kahore pānga kitea i runga i te wā o te oscillation o te tāwēwē pāngarau ko negligibly iti, na araia te ratou mana i te whakaaro.

Whakatau i o te wā o oscillation o te tautau, ki te kahore te māmā mohiotia e papaki ko tenei: ko te wā - te wa i roto i nei e tuu kotahi oscillation oti. Kia hanga o te tohu i roto i tetahi o nga ngā tino o te kaupapa o te utanga. Na wa katoa te katia te wāhi, hanga tatau te maha o oscillations oti, me te mōhio i te wa o, mea, 100 wiri. Te whakatau i te roanga o tetahi wā ko te putunga. kawe matou i tenei whakamātau mō te kōpiupiu i roto i tetahi waka rererangi o te tāwēwē i roto i te wā e whai ake nei:

- rerekē tīwera tuatahi;

- rerekē taimaha kawenga.

Ka whiwhi tatou hua auheke i mawhiti tuatahi: i roto i wā katoa, tonu te wā o te oscillation tāwēwē ohie tonu. I roto i te mau parau te tahi atu, te kaha tīwera, me te papatipu tuatahi o te pūwāhi rauemi i runga i te roanga o te wā e kore e faaitoito mana. Hoki kōrero atu ko te kotahi anake te paku - no te mea kawenga teitei ka peia huringa, ka te kaha whakaora taha te tāupe ara, i te mea ērā mō tātaitanga. Paku tinihanga - Pana tautau ano i roto i te ahunga hake - haamata te reira ki te whakaahua i te mata koeke, te wā T o hurihanga tonu te taua, te tere o te kaupapa me te paenga V - tamau paenga, haere nei neke te utanga S = 2πr, he kaha te whakaora whakahaua haere te pūtoro.

Na ka tātai tatou te wā o te oscillation o te tāwēwē ohie:

T = S / V = 2πr / v

Ki te he iti te roa o te l miro tino atu te rahi utanga (i te iti rawa 15-20 wa), me te koki miro o te tokonga ake (tīwera iti), ka taea e tatou amo e he rite ki te F kaha centripetal nga whakaora i kaha P:
P = F = m * V * V / r

I te tahi atu te ringa, te wa o te kaha whakaora me te kau o te tūpuku o he rite te kawenga, me ka

P * l = r * (m * g), e uhinga a tango ki pūkete e P = F, te whārite e whai ake nei: r * m * g / l = m * v * v / r

E kore e uaua ki te kitea te tere o te tāwēwē: v = r * √g / l.

Na inaianei mahara te faaiteraa rawa tuatahi mo te wā, me te whakauru i te uara o te tere:

T = 2πr / r * √g / l

I muri i te hurihanga wā tātai ore oscillation tautau pāngarau i roto i te puka whakamutunga ko e whai ake:

T = 2 π √ l / g

Na kua whakapumautia hua mua experimentally whiwhi o te rangatiratanga o te wā oscillation o te taimaha o te kawenga me te kaha tīwera i roto i te puka tātari, me te e kore e titiro ki te e na "mīharo", rite ki te mea ratou, rite hiahiatia.

I roto i te tahi atu mea, penei i te faaiteraa whakamutunga mo te wā o oscillation o te tautau pāngarau, ka taea e kite koe i ha faingamālie pai ki te ine i te whakatere o te mahara. Ko reira ranea ki te huihui i te tāwēwē tohutoro i tetahi wāhi o te whenua, me te ki te ine i te wā o ona oscillations. A pera, tino ohorere, kua homai he tāwēwē ohie, me te māmā tatou ha faingamālie pai ki te ako i te tohatoha o te kiato o te kirinuku o Papatūānuku, ki runga ki te rapu putunga kohuke whenua. Ko e te tetahi atu kōrero.
