Yintoni esele? Uhlalutyo olunzulu

Eli nqaku ibalisa yintoni na isikali ngokufutshane ibali kwendalo yazo kwaye ingqalelo iintlobo ezimbini - kunye ekhishini.

Amaxesha amandulo

Ukususela kwixesha lakudala, ekuqaleni kobudlelwane zorhwebo olubanzi abantu baye babona imfuneko ukufumanisa ngokuchanekileyo ubunzima kunye nobungakanani impahla ethile. Ke ukuba, umzekelo, nokudla okuziinkozo efanayo kulula (uyakwazi ndiyilinganisele amabhakethi kunye nezinye izikhongozeli), ngoko kuthekani okungakumbi yaye ubunzima ezahlukeneyo mbini, ezifana iinkukhu, inyama kunye nezinye iimveliso nesypuchimi? Izikali yokuqala afunyanwa yi abembi asusela V nkulungwane BC kwaye zenziwe eMesopotamiya. Kwakhona, le fowuni kubonakala kakuhle kwimipapiri eYiputa yamandulo, leyo imihla ukususela kunyaka 1250 BC. e. Kodwa yintoni na isikali yaye yintoni na ke?

definition

Ngokutsho kwesigama esemthethweni siyaqabela - isixhobo yokuqingqa ubunzima echanileyo into ngokuvelisa indlela yangaphakathi okanye uthelekiso kunye inani. Eyokuqala isikali, nto ixesha elide isetyenziswe kulo lonke ihlabathi ziye lever. ukuba lingohluka, kodwa umgaqo ibisoloko simanywe ngembonakalo, indlela ezikhathaza. Eyona idumileyo - espan. Ndabeka kwelinye icala iimpahla, kunye nezinye - umthwalo reference (enye okanye ngaphezulu). Xa uthwele omabini kumiselwa ubunzima. Ngokuchanekileyo

Ukuze ukuba isikali enjalo, siyaqonda, kodwa yintoni isisekelo kumgangatho mihla kunye efanayo?

isimiso ukusebenza

Kukho iintlobo ezintlanu. Le azisebenzisele, intwasahlobo (apho ubunzima emiselwe yi iqondo ucinezelo okanye ndisolulela spirally nxeba ingxenye metal) ubunzima (deformation kwenzeka apho woluvo ezichaphazelekayo) hydrostatic (apho umgaqo isekelwe kaArchimedes 'umgaqo) kunye ngesanti kubunzulu baphantsi.

Eyona ixhaphakileyo spring ukukhathaza basekhaya, njengoko bazenze zambi ubungakanani elincinane, kwaye zokugqibela echanekileyo amaqhezu gram. Ngoku siyazi into scales and yintoni na umgaqo yesenzo sabo. Makhe sithethe ixhaphakileyo ukusetyenziswa okanye imveliso - kumgangatho kunye nekhitshi.

Floor

izixhobo ezo zisetyenziselwa isigqibo ubunzima amashishini asebenza imithwalo mbini ezibanzi, leyo kube lula ukubeka kwaye inobunzima emgangathweni, umzekelo, kwi-ofisi yeposi. Kwimeko yokugqibela, kufuneka kuzinza, oluchanekileyo ixesha elide.

Indawo yesibini besicelo - yasekhaya kuphela. Apha, isikali umgangatho ziyafuneka ukumisela ubunzima kubantu ababukele ubunzima lwabo. Umzekelo, iimbaleki okanye ufuna nje ukuncipha. Bona luphawulwa ubungakanani amancinci kunye balo babulingana nesandla, senze emthonjeni okanye uhlobo gauge basis. Kwimeko yokuqala, basebenza ngaphandle kwalo naluphi na unikezelo lwamandla, kunye nemfuno ibhetri yesibini. Nangona ezinye iimodeli efakiweyo panels ezincinane solar ukuba imali imizuzwana elishumi ngakanye zokugcina amandla.

izikali Kitchen

ezikalini ezinjalo zokudlela ikakhulu lwamayeza kunye nezinye iindawo loo ukuvelisa ukutya. Zezi echanekileyo amaqhezu gram, ubungakanani elincinane, ekhuselweyo ukufuma, ubumdaka kunye amaqondo obushushu aphezulu.

Kwakhona, isikali zamakhitshi asetyenziselwa iinjongo zasendlwini, ekuphekeni, nto leyo mass ngqo ngokukodwa ebalulekileyo lwezithako.

ezinye izicelo

Ngaphandle namatye ungenza ukwenza inani neminye imibutho kunye amacandelo. Zimisela ubunzima yomthwalo abakhweli kwi-moya, elininzi izigadla phezu amasiko kunye bekwilift, isikhongozeli amazibuko ezinjengeetheminali zikaloliwe. zithengise ukutya - indawo apho sikwazi ukubona ezahlukeneyo kwizikali zokuguqulwa rhoqo.

Lo iqhekeza ebalulekileyo izixhobo kwi iilebhu imichiza, ngokwasemzimbeni kunye amayeza kunye namashishini lweendawo ezifanelekileyo apho components ngqo ubunzima kubaluleke kakhulu.

Ngoku siyazi ukuba ezikalini, into abayenzayo kwaye zeziphi na iintlobo eziphambili zezi zixhobo ezikhoyo namhlanje.
