Nzira yekuverenga yakajeka

Chero chinhu chipi nechipi chine maitiro. Uye iyo huru yemamiriro ezvinhu chero ipi zvayo-uremu, kana kuti panzvimbo--kureruka kwakakwana, chiyero chekurehwa kwemumwe muviri uye ivhu rinoitwa nemuviri uyu. Ichi chinoratidzira chinotevera kubva kumatsananguro ekugadzirisa nyaya. Iko kuburikidza naye iye kuti tiri kuita shanduko kune imwe nzvimbo yemafanirwo ekufananidzira. Nyaya kwatiri haisisiri masorphous mass, tichiedza nzvimbo yayo yekuvhiti. Zvakanaka, somuenzaniso - yezuva masikati - miviri yayo yose yakasiyana maererano nehukuru hunokwana (sei kuverenga hukuru hunokwana - zvishoma pasi), nokuti vane utera hwavo uye ivhu. Kana tikatora pasi redu nemakondohwe ayo (lithosphere, hydrosphere, mumhepo) zvakasiyana, zvinosvika kuti ivo vanewo simba ravo, rakasiyana uye rakasiyana.

Saizvozvowo, munhu mumwechete chemakemikari ane uremu hwake, chete atomic imwe. Izvi zvinorevawo kukurumbira. Nenzira, kune zvishoma zvichemo zvinogona kumira mumhando yakachena, uye mamwe ose-makemikari, sekutonga, akasimba uye ane zita rezvinhu zviri nyore. Muchi lithosphere yepasi redu pane mazana mashanu, imwe neimwe ine simba rakananga. Nzira yekuverenga yakajeka sei? Uye zvakadaro, izvi zvingaitwa here?

Zvechokwadi. Parizvino, tichaona maitiro ekuverenga chiremera chaiyo. Zviri nani kuita izvi pane mienzaniso chaiyo, kuitira kuti zvinyatsonzwisisika.

1. Somuenzaniso, iwe ndiwe musoro wechitoro chekuveza uye unoda kuziva kuverenga kwehuwandu hunorema hwekutengesa zvimwe zvinhu kana kushanda mune imwe nyaya. Inofanira kuzivikanwa: ukuru hwekutengeswa kweimwe chigadzirwa uye izwi rose. Ngatitii tine: chigadzirwa chemhando - bhodhi, mari - 15500 (rub), kuyerwa kwemasero - 81.6%; Mhando yemhando - matanda, mari - 30000 (rub), chiremera chakakwana 15.8%; Mhando yemhando - croaker, mari - 190000 (rub), chiremera chakakwana 2.6%. Zvose: mari - 190,000, uye huwandu hunorema (huwandu), maererano, 100%. Nzira yekuverenga sei chiremera chaiyo chebhodhi? Tinoparadzanisa 155,000 ne 190 000 uye tinowedzera nezana. Tinowana 81.6%. Ichi ndicho chiremera chaiyo chebhodhi.

2. Kuverenga sei kukwirira kwezvimwe zvinhu?

Chiremera chakakosha pane chimwe chikonzero chinowanzovhiringidzika nehuwandu hwevanhu, kunyange pfungwa idzi dzakasiyana zvachose. Izvo zvakashata hazvirevi maitiro e physicochemical uye zvinopesana nehuwandu hwemashoko, somuenzaniso, kuyerwa nekuyera.

2.1.) Kuwedzerwa - huwandu hwehukuru kusvika kuhuwandu, uye hukuru hunokwana - chiyero chekuyera kusvika kuhuwandu, chirevo ichi chingafananidzirwa seizvi: γ = mg / V. Uye kana huwandu huwandu hwehuwandu hwemuviri hwakapiwa kuhuwandu hwemuviri uyu, zvino tinonyora murairo wekuwana simba rakajeka, muchimiro ichi: γ = ρg.

2.2.) Kana uchida, zvinokwanisika kuwana hukuru hunoshandiswa kuburikidza nehuwandu uye huwandu, kana nenzira yekuedza, nekuenzanisa zvinodzvinyirira. Pano hydrostatics equation ichashandiswa: P = Po + γh. Asi iyo nzira inoshanda chete munyaya iyo iyo yose inoyera yakawanda inozivikanwa pasina kunze. Muchiitiko ichi, chirevo chekuwana chiremera chaicho chinotora fomu inotevera: γ = P-Po / h. Ichi chiyano chinowanzoshandiswa kurondedzera kukurukurirana midziyo uye zvavanoita. Pamusoro peshoko rekuedza, mhedzisiro yakarurama ndeyekuti: zvinhu zvose mumidziyo yekukurukurirana zvichava nehupamhi hwayo uye iyo inopararira mberi kwayo pamadziro emudziyo umo chinhu ichi chiripo.

2.3.) Kuti tivere (kuverenga) simba rakajeka, tinogona kushandisa rimwe rumbiro (Archimedes 'simba). Unoyeuka zvidzidzo zvekuchikoro mune physics? Zvichida, vashomanana chete ndivo vachapindura mubvunzo. Nokudaro, tinovandudza chiyeuchidzo: simba reArchimedes-sila riri kukurira . Ngatitaurei kuti tine nhumbi nemamwe mashoma (ticharatidza mutoro uyu se "m"), unochengetwa pamvura. Panguva ino, mauto maviri anobata pamutoro, wekutanga ndiye simba guru, uye wechipiri Archimedes (simba rinosundira, uye rinodzokera kune vector mg). Muchirevo chacho, simba raArchimedes rinoratidzika seizvi: Fapx = ρgV. Kuziva kuti ρg yakaenzana nechiremera chakakwana chemvura, tinowana kuenzanirana kunotevera: Fapx = yV, uye kubva pane ino tinowana: y = Fapx / V.

Zvakaoma here? Zvadaro ita nyore: kuitira kuti uverenge simba rakananga, aparadzanisa uremu nehuwandu.
