Umsebenzi Mechanical - nto wena ucinga ntoni

Yintoni umsebenzi, ukuba wazi yonk 'into. Nkqu nabantwana basebenza enkulisa - kids. Nangona kunjalo, lo, ukumelwa yasekhaya eqhelekileyo ayikho into efanayo njengoko ingqiqo umsebenzi lomatshini physics. Ngokomzekelo, umntu esimiyo ubamba kwibhegi. Ngengqiqo njengesiqhelo, wenza lo msebenzi, ephethe umthwalo. Noko ke, ukususela kwinqanaba Ngenxa physics, akazange enze nto njengaye. Yintoni ingxaki?

Xa kukho imibuzo enjalo, lixesha lokuba ukukhumbula le nkcazelo. Xa izenzo ukusebenza into, naphantsi intshukumo yomzimba isusiwe, ngoko ke umsebenzi ngoomatshini. Le ixabiso ngokomlinganiselo indlela ababehamba ngayo umzimba kunye nomkhosi isicelo. Kukho uxhomekeke kakhulu kwicala lwesicelo inguwo ulwalathiso sesindululo somzimba nangoku.

Ngenxa yoko, siye sasungula into efana umsebenzi ngoomatshini. Physics ikuchaza ngokuthi imveliso kwamaxesha amandla kunye ukubana i cosine ye ixabiso engile langoku kwimeko therebetween jikelele. Ngokomzekelo, cinga nje ezimbalwa, ukuba uya kuyazi into kuthethwa ngalo.

Xa umsebenzi ngoomatshini na kwenziwa? Truck limi, siya ukutyhala, kwaye ayithethi ukuhamba. sifakwa amandla, kwaye akukho ntshukumo. Owenza umsebenzi ilingana zero. Kwaye nantsi omnye umzekelo - umama ethwele umntwana esinamavili, kwimeko apho kwenziwa umsebenzi, sifakwa amandla, ezizukileyo isusiwe. Umahluko kwezi meko ezimbini echazwe phambi ukufuduka. Kwaye ke, lo msebenzi wenziwa (umzekelo wenqwelwana), okanye (umzekelo nge kwilori).

Elinye icala - inkwenkwe ngebhayisekile kunye saa ngoxolo uzibhuqa kwingoma, lo enyovwayo a akufunekanga bajije. Umsebenzi wenziwa? Akunjalo, nangona intshukumo apho, kodwa akukho amandla isicelo, isindululo kudluliselwa inertia.

Omnye umzekelo - inqwelo eqhutywa ihashe, umqhubi ohleli kuyo. ukuba kuyasebenza oko? Ukuqhubekela apho, amandla isicelo yi (ubunzima nomqhubi bukaThixo enqwelweni), kodwa umsebenzi akwenziwanga. I-engile ephakathi ngakwicala intshukumo kunye ulwalathiso mandla 90, yaye i cosine ye 90 ° ngu zero.

Le mizekelo kwenza kube lula ukuqonda ukuba umsebenzi mechanical - ukuba nje imveliso lwamaxabiso ezimbini. Kufuneka kwakhona athathe ingqalelo indlela ethunyelwa yala maxabiso. Ukuba kwicala ukuhamba kunye nolwalathiso yomkhosi ayafana, umphumo uya kuba HIV ukuba indlela yeentshukumo kwenzeka ngokuchasene kolwalathiso isicelo amandla, isiphumo negative (umzekelo, umsebenzi owenziwa yi-amandla frictional xa uhambisa umthwalo).

Ukongeza, kufuneka ucinge ukuba ebambeleyo ekhankanyiweyo amandla omzimba kuba nomphumela imikhosi eziliqela. Ukuba kunjalo, ngoko ke umsebenzi yonke imikhosi isicelo umzimba elingana ngomsebenzi owenziweyo yi-amandla isiphumo. Umsebenzi ulinganiswa ziijowule. Enye esiyijowule na umsebenzi eyenza amandla newton omnye xa umzimba ihamba kwimitha eyodwa.

Ukususela le mizekelo ingasentla kunokuba kwisigqibo umdla kakhulu. Xa Wajonga wenqwelo enqwelweni, bubungakanani ukuba ayenzi umsebenzi. Umsebenzi lwenziwa kwi-moya tyaba, ngokuba kulapho yenziwa ukudluliswa. Kodwa ke imeko isuntswana eyahlukileyo xa siqwalasela ngeenyawo.

Xa uhamba, iziko womxhuzulane yomntu akuthethi sihlale simile, siya moya nkqo yaye, ke ngoko, wenza umsebenzi. Kwaye njengoko intshukumo sibhekiswe amandla umtsalane, ngoko ke msebenzi uya kuqhubeka ngokuchasene kolwalathiso amanyathelo womxhuzulane. Vumela intshukumo kunye encinane, kodwa kudala uhamba umzimba kuya kufuneka ukuba enze umsebenzi owongezelelekileyo. Ngoko umlenze echanekileyo kunciphisa umsebenzi engakumbi kunciphisa nokudinwa.

Emva kokuhlalutya inani zeemeko ubomi obulula, okhethiweyo njengemizekelo, yaye usebenzisa ulwazi lo msebenzi mechanical, siye saxubusha imeko ezisisiseko obubonakala, kwakunye nomsebenzi lwenziwa nini kwaye njani. Sizimisele ukuba onjalo ngqikelelo njengoko umsebenzi ekhaya kwaye physics inophawu eyahlukileyo. Iqinisekile ngokusebenzisa imithetho yemvelo iqinelwa engaqhelekanga ebangela ukudinwa olongezelelweyo.
