Intshukumo rotary njengendlela uthutha emajukujukwini

Makhe sicinge - iisosi eziphaphazelayo, ingaba ngumkhuba yokwenene ngokomgangatho wophando kwizifundo, kwaye ingaba kukho nayiphi na ingcaciso efanelekileyo kule meko? Ekuqaleni, masikhumbule oko sele kwafika kubo bonke. zesayensi kwizifundo bungqinelwa into yokuba nayiphi na intshukumo kufuneka lwandulelwe isizathu. Kungenjalo, le nto ikwabizwa ngokuba "kuthethwa 'intshukumo, apho ubunzima umzimba ihamba, kuquka nokuba intshukumo rotary, ukuba angaphumelela ngamanye intlama.

Kwiinkqubo ezivaliweyo udibaniso yonke imikhosi yangaphandle, isoloko okufanayo. Ngamafutshane, embindini nayiphi na intshukumo okwenzeka ehlabathini kwisithuba orbit bafunda ngokwaso seredinka umhlaba. Lo mthetho ulawula zonke izinto zonke izithuthi yaziwe ehlabathini namhlanje.

Imithetho-siseko eyinqobo, ngokusekelwe apho bonke ubunzima unxibelelwano kwisithuba closed, oko kukuthi i-Earth, nimkhonze ezintathu umthetho Newton, ezizezi umthetho zolondolozo amandla, umthetho nomthetho la ye umfutho emboxo. Ukuba ingcaciso echanekileyo kwezi mithetho hayi kunokwenziwa isigqibo sokuba kumbindi mass indawo evaliweyo apho nentshukumo ejikelezayo lihlala rhoqo.

Ingaba ikhona enye yamandla agciniweyo of motion rotation, nto leyo esekelwe kwi intshukumo isimaphambili se imikhosi yangaphandle, leyo i "support"? Ethetha umzekelo.

Masithi kufuneka itankana ngeenxa itankana kwi sphere eqhelekileyo, anamandla kakhulu yaye ikhaphukhaphu ujikeleza ibhola encinci. Xa uyila okubulala encinane ngasemva kwebhola (dubulo), ngokomthetho yesibini Newton, ngesantya ibhola utshintsho wokutshintsha kufuneka kwenzeke ngokomlinganiselo isiphumo kuyo ngamandla (ithetha ukuba amandla dubulo), kunye nentshukumo kufuneka ibhekiswe ecaleni umgca ngqo ngendlela apho amandla umonakalo kwaba iqhotyoshelwe apha.

Kwenzeka ntoni kulo, umzekelo ethile? Owesibini umthetho Newton a Makangagocagoci phakathi indlela ukuya translational okanye ejikelezayo. Ngenxa yoko, le nentshukumo ejikelezayo kunye translational lombhobho kufuneka kuqwalaselwe ngamandla ngokulinganayo lisetyenziswa lombhobho. Kubonakala ukuba olujikelezayo ngeenxa zonke ezinye yomzimba isifundo nalo zibhekisela kulo mzimba phambili kwaye isindululo yomgama, indlela apho ingqamana ulwalathiso amandla isicelo.

Oku kuthetha ngqo kunye isindululo translational bento eyodwa kunokubangela amandla leyo uvelisa umsebenzi kunye isindululo ojikelezayo enye into. Isilinda, kulo mzekelo, inobunzima elikhulu, xa kuthelekiswa ibhola. Ukuba oku akunjalo, intshukumo esqwini engundoqo lombhobho kuya kuthetha kwintshukumo rotary ibhola. Nakuba kunjalo, ukuhlola umzekelo yethu, sithi ukuba unalo ilungelo lokuba khona, inertia ezinjalo, apho amandla isicelo kwiziko lombhobho kuzodala ngqo kunye phambili eshukumayo.

Ngoko ke, lo isindululo ojikelezayo bento eyodwa kunokubangela isiphakamiso rectilinear kwaye Buyisela ke omnye, kwaye umthetho zontathu umthetho Newton.

isayensi Modern sele yafika urhulumente ukuba uyakwazi ukuyila injini 'ayixhaswanga "esisebenzisa sizukulwana eqhubekayo, evaliweyo inkqubo loop namandla nto leyo idala isindululo rotary. Le ndlela intshukumo anokusetyenziswa nasiphi na isithuthi, ngebhayisekile, yaye ukuya esosini eziphaphazelayo, kunye neendleko-ngempumelelo kwale nkqubo iya kuba into eyogqitha.
