Masimba ari hurongwa. The chairema simba mune hurongwa

Masimba ari hurongwa anowanzodanwa anozviratidza muchikamu ichi chiri simba. Zvaiva imomo kuti akadzidza kufamba kwemiviri kufungisisa mauto kuita pamusoro pavo. Ndiyo simba hurongwa izvo zvakasikwa vane uye zvavangaita kuti akaverenga, nhasi tichataura.

Chii hwaro rinomutsa

Sezvambotaurwa, hurongwa kwesimba anozviratidza inonyanyoshandiswa muchikamu chino. Uye kana zvakadaro, pachava zvinopfuura kuziva kuti kazhinji ndiyo yokungotaura hwaro nezvokuvapo simba. Zvichida mumwe yakatotanga wafungidzira kuti tiri kutaura pamusoro yakakurumbira Isaac Newton, kana pane, mitemo yaiwana navo. The chairema simba hurongwa, nenzira, ndicho chikonzero, uye inobereka zita rake.

Kuti isu kubvumira mitemo Newton raMwari?

Vanobvumira isu kugadzirisa chinetso chikuru mune chiitiko kuti zvinovinga vamwe kuvazivisa dzose masimba kuita pane imwe nguva iri bvunzo muviri. Ngationei kufunga kuti ichi ichokwadi, uye tinoziva navo. Zvadaro tinogona kuwana kumhanyisa, kushandiswawo muviri hakuna kumbondinetsa. Asi kuziva kuti mune kwakakura uye mirayiridzo ndiye kumhanyisa, achavhura pamberi pedu muviri nokukurumidza kutsvaka tarisiro chero achida nguva. Somugumisiro, tinogona kuona nzvimbo ine zvinhu pfungwa apo tinoda. Unogona kusimbisa kukosha uye Ivan Kuchin dambudziko. Zvakaratidza kuti kugadzirisa matambudziko pakutanga vanofanira zvakanaka kuronga masimba mune hurongwa, uko nzira achapiwa pazasi.

Nature mauto

Kana isu kuzarura bhuku, bhuku matambudziko wefizikisi kana mamwe mashoko uye kureva Vanamakanika, tinoona yakawanda zvinetso emuchina, apo inonyanyoshandiswa atarisana namapoka matatu chete. Ivo inoshandawo kune rinokwevera zvinhu pasi, kukweshera uye elasticity. Ngatitaurei pamusoro mumwe nomumwe wavo zvizere. Uye Ngatitangei yokutanga.

The muviri chikawira kubva kumusoro, pasina kutanga nokukurumidza

vari nyaya dzakadaro inonzi akasununguka kuwa. Zvose tichigara uchifarira redu. Kusanganisira isu. Pano unogona kuona chokwadi ichi wesimba rinokwevera zvinhu pasi mauto. Zvino tinogona hanya mhepo nemishonga, kunyange zvazvo izvi hazvisi nguva dzose musoro. Asi chii isu kuwana? Zvino uya, kuti mitumbi yose ndezvomuzana zvakafanana kumhanyisa murusununguko kuwa. Regai kukanda chiduku ibwe kana cobblestone chaicho pasi - nokukurumidza uye kuwa ichava pamusoro chete.

Kuchawedzera kutsime hurongwa

Fungidzira kuti chitubu akarembedzwa sinker. Iye, kufanana mumwe muviri, vanowanzotevedzera pasi. Panguva ino, zvakanga anoita simba kukwezvana nyika yedu. Zvisinei, kana tsime riri simba, zvichava ruchatambanudzirwa kune imwe pfungwa. Pashure paizvozvo, muviri achamira kuwa hurongwa vachauya ezvinhu anonzi zvokuimba zvakanyatsoenzana. Zvinotora nzvimbo kana chiito pamusoro muviri vari mauto akawanda, asi mari yavo razero. Nemamwe mashoko, Zvakaitwa nemauto vari ndanyarara hangu.

Pano anotanga kukumbira vatiwo. Zvakaratidza kuti kuwedzera simba regiravhiti pamusoro uremu kudivi chitubu ane zvimwe simba kuti dziwande kukwezvana vakaenzana. It ane zita nyore chaizvo inopiwa chinonakidza. It akadana ayo kwakavharwa nenyama simba. The chairema simba mune hurongwa iri pasi nokudenga, uye ipapo iye, zvakare, akaenzana mumwe Newton.

Ko kumhanyisa - chikonzero mwero shanduko?

Pamwe. Pakutanga, zvinhu zvose sezvo zvinoita. Asi kana imi kuchera zvakadzika, zviri zvakakwana kutora inonakidza dzoro. Pane chinhu chinoshamisa murayiro Newton (wechipiri), iro rinoti simba kuenzana gobvu nguva kumhanyisa kundiwedzera kumuviri. Pakutanga zvingaita sokuti (chete mathematically) kuti simba ndiwo mugumisiro. Asi aripo, chokwadi, ichokwadi zvakasiyana.

Fungidzira bhora, nokuti urove. Akashuma simba, uye ipapo anowana mumwe kumhanyisa. Saizvozvowo, pane nyaya kufamba muviri. It inopfuura chimwe kure, mira. Kumhanyisa achava asina kunaka sokuvapo velocity akaenzana razero. Tinogona pakarepo kuisa mberi nokufungidzira kuti anowanikwa simba kuti DZEMUNHU DZINODZORA muviri, kuti chinokonzera izvi kunaka kwazvo kumhanyisa. Uye ariko zvechokwadi. Izvi frictional simba.

Nechinguvana simba. Mechanics: yokungotaura uye hwokugadzira

Nhambo simba ichanzi rotational simba kunotangira vachishandisa kutenderera rehondo Vector noruremekedzo kusvikira kana kunditsoropodza muviri. It ane divi kuti Newton muzana mita. chiitiko ezvinhu zviri nyore. Zviri zvakakwana kuti pfungwa nhema pamusoro yakayerwa simba. Sarudza pfungwa zvinogonawo zvinobikwa simba uye zvireruke. The nyore muenzaniso ndiyo monyorora nati ane chipanera. Simba yokungotaura hurongwa kashoma inosiyana analogues ayo ari dzekare chikamu, saka zvinoita njere yakawanda yokunyatsoongorora kuti uwane kukurukurwa. Ngatidzokerei kune zvinokosha, nekuti ivo zvikuru kukosha.

Zvakare, simba elasticity

Muverengi anogona nguva dzose pachake kutarisa zviri parizvino yakati. Ngatitii tine muviri hwakasimba. Chero hwakasimba inopa nemishonga kana vachiedza kushandura chimiro, ukuru. Asi mudzimu aya hapana chimwe pane nyore deformation, zvakarurama? Asi chii ayo mhando? Kune mhando shanu inokosha deformation: makakatanwa, compression, vachikotama, torsion, Sheari.

Chii chichaitika kana ukaedza kushandura chimiro uye kukura?

It zvinoenderana yezvakaita muviri. Kazhinji, deformation ndiyo kwakavharwa nenyama uye kwete kwakavharwa nenyama. Asi iwe unofanira kuziva kuti chero kuedza kushandura chimiro uye kukura kwomuviri, zvichaita kuedza avadzose. Pakadaro, kana deformation iri diki zvichienzaniswa yepakutanga kukura, asi kwakavharwa nenyama mauto ichi chinogona kuitwa. Chimwe chinhu, kana mamiriro acho ezvinhu akasiyana chaizvo. Asi ongororo azvaiitwa atopiwa aidaro musayendisiti Robert guk. kuedza ake, waiita zvakadzama nhau yacho deformation kwacho mitumbi, akanga ari 1660.

Chii akaita musayendisiti ichi?

Akatora panozogadzirika zvakaoma, izvo zvakatanga ruoko. Kana izvi zvakaitika mukati tsvimbo, sezvo inogona wafungidzira, ari kwakavharwa nenyama simba. Zvinonzi akayera mu muitiro kutambanuka. Kutsanangura muitiro tichitarisa yakawanda, kupinda kukosha itsva, akashevedza elongation. Ichi chimwe kunze musiyano Linear kukura mumuviri uye huine mune vanhuwo mamiriro. The experimental Migumisiro kunyange zvakashamisa vamwe. Somugumisiro, panyaya deformations duku pakati elongation uye kwakavharwa nenyama simba rine zvakananga Proportional ukama. Pano tine imwe kukosha, izvo isu kudaidzo coefficient ose elasticity. It zvinoenderana mashoko iyo muviri wakaita, uye pane zvainazvo Linear miganhu.
