Chii anonzi nguva simba? Sei vanokurondedzera?

Ngatiedzei kufunga chii inonzi simba pfungwa. Izwi iri rinowanzoshandiswa wefizikisi. Vakaongorora pasi rinoreva basa papfudzi uye kurerekera simba rake.

Features

Ongorora mubvunzo zvinonzi Nguva simba zvinokosha kutaura uye vamapoka ukoshi ichi. Muna SI gadziriro nayo unotaurwa Numbers.

torque

Torque ane simba pamusoro pfungwa zvakakoshera chokuita zvireruke uye simba. Muupenyu hwezuva nezuva, vanhu kazhinji vanoshandisa "mhikuriso pokutonga", iro kunobva chaiyo iri simba pfungwa.

Somuenzaniso, kuti zvienderane-famba, tinofanira kuziva anonzi nguva simba, uye kuti zvakanaka batanidza. Papfudzi inonzi penguva pakati application pfungwa uye pivot pfungwa.

Somuenzaniso, zvakaoma kuvhura musuo, kungoita izvozvo kubva hwakawanda pfungwa. Kuti tinzwisise nei izvi zvakadaro zvakaoma kuita, unofanira kuziva chii anonzi nguva imwe simba pamusoro akabatana.

Ngatitii kuti unofanira kuvhura musuo, une upamhi meter, annexing 100 N. Kushandisa zvinofanira kuva munzvimbo nhatu:

• pedo zvamagonhi;
• pakati;
• panguva kumucheto kanivhasi.

Nokuti kutanga nyaya pamafudzi iri razero, naizvozvo, basa riri ruoko achapiwa ndikazoti simba ukoshi razero.

Nokuti kuita pakati pamukova, nguva achaita anoenderana 50 Shona. To pasi pamukova shizha pfungwa achava kunonyanyisa ukoshi 100 Shona.

Masvomhu kwakadaro kuti zvinoita kugumisa kuti kurasikirwa Daro ndanyarara hangu achishandisa fuma iri kutamburira.

rorudyi

Kana kushandisa rimwe simba panguva necheparutivi, hazvibviri kutaura pamusoro Pakusarudza mauto papfudzi sezvo zvaionekwa ambotaurwa. Kutsungirira basa iri, unofanira kushandisa rorudyi. Pamafudzi mauto anonzi perpendicular kureba kuti Haatauri kubva pivot pfungwa pamusoro mutsetse kuita hondo.

Kuti uone ruoko simba, kuwedzera mutsetse. Zvadaro iri akatura perpendicular kubva pivot pfungwa.

Zvinoguma netriangle rworudyi pamakona. Uchishandisa nemitemo trigonometry, zvinokwanisika kuburikidza sinus kuona Nguva simba.

Kufunga kuti simba rinoshanda panguva necheparutivi rworwendo 45. Panyaya iyi, nguva vakawana 70 Shona. Zvinova pachena kuti kwete kushanda kuvhura pamukova necheparutivi of 0 inegumi. simba kwakadaro hakuna maberere kuti aigona kukonzera rotational sangano. Pasina papfudzi rake, kunze zero, haabvumiri simba rokusika torque. Kufungisisa zviri kunzi nguva simba, zvinofanira kucherechedzwa kuti munhu vector uwandu. Kuti tizive mirayiridzo Nguva simba, shandisa -ruoko rworudyi utongi. Saizvozvowo, kuona vatungamirire vektori chisina kutsetseka velocity.

Chii chinokosha pamusoro pokutonga ichi? Fukidza muchanza rworudyi akabatana kuti kutenderera, saka kuti kutungamirirwa minwe dzichienderana mirayiridzo yacho Zvakarurama simba. Napagumwe roruoko dzichiita ari chisina kutsetseka tichimhanya Vector kuti simba. Chii anonzi nguva imwe simba pamusoro yakamisirwa pfungwa? kukosha ichi, izvo rinobatanidza fungidziro pamusoro Vector simba nguva uye akabatana pamusoro iyo kukarukureta chichaitwa.

Pfungwa huru simba ndiro Vector inova Verengai vanhu vose nguva wacho masimba kuti ashande munyika panyaya pfungwa yakafanana. Her kufona centre kuunza hurongwa yose mauto.

In mukuru musimboti, mugumisiro chiito chimwe hwakasimba hurongwa kwakafanana Zvakaitwa torque huru ino uyewo Vector mauto kureva musimboti kutyaira.

mhedziso

Nokuti rondedzero torque akashandisa unokosha mutemo emuchina, iyo inechirevo ari rotational inofamba. Anorondedzera kuti nguva inertia, chisina kutsetseka kumhanyisa, torque. Mushure Archimedes akasimbisa zvakarurama ruoko, pasina chinhu transformations rave richishandiswa anenge 1,900 makore. Chete yechipiri yezana musayendisiti French remakore rechi17 P. Pierre Varignon akanga achinja uye nokuda torque mauto.

Kana mhikuriso ari zvakanyatsoenzana, wakaenzana M1 = M2. Torque ndiye anozivikanwa pakati rotational simba chiito. Zvinoenderana kwete simba asiwo pafudzi rake. Kuti sunungura nati, vanoshandisa refu chipanera. Screws nokukurumidza vakakosa sikurudhiraivha ane zvakakwana refu mubato.
