Isihloko mayelana nezinhlobo zokulingana kwe umzimba oqinile
Akuzona zonke izinto esizithola ekuphileni kwansuku zonke ezihlala ziphumula. Mhlawumbe ekuqaleni into iyaphumula, kodwa uma ishukunyiswa (isibonelo ngumoya) izinto zingashukuma. Inkinga iwukuthi, noma ngabe ngemva kokuhamba, izinto zibuyela endaweni yazo yokuqala noma cha. Lokhu kuncike ohlotsheni lokulinganisela kwento. Ngemva kokuhamba, kuzoba namathuba amathathu, okungukuthi:
(1) into ibuyela endaweni yayo yokuqala,
(2) into isuka endaweni yayo yokuqala,
(3) into ihlala isendaweni yayo entsha.
Uma ngemva kokubuyisela into endaweni yayo yokuqala, into isesimweni esizinzile. Uma ngemva kokuhamba, into iqhubekela phambili nakakhulu, khona-ke into isesimweni esizinzile. Ngokuphambene nalokho, uma ngemva kokuhamba, into ihlale esimweni sayo esisha, khona-ke into isesimweni esingathathi hlangothi.
1. Ukulingana okuzinzile
Into eqale yabekwa, uma isebenzise amandla noma i-torque kuyo (kukhona amandla noma umzuzu wamandla ophumelayo) khona-ke into izohamba. Ukulingana kuzinzile uma, ngemva kokuhamba, into ibuyela endaweni yayo yokuqala. Izinto ezihambayo zibuyela endaweni yazo yokuqala ngenxa yamandla noma umzuzu wamandla ophumelayo ovele ngemva kokuhamba kwento.
Isibonelo 1. Into ilenga ngentambo ku-buffer. Okokuqala, into iphumula. Ngemva kokusunduzwa, into iyahamba bese into ibuyela endaweni yayo yokuqala. Isisindo sento siphakathi nendawo yento, kuyilapho iphuzu lokusekela liphakathi kwentambo nokusekela. Izinto ezihambayo zibuyela endaweni yazo yokuqala ngenxa yamandla adonsela phansi avelayo ohlangothini oluvundlile (wx). Ukucindezeleka kwentambo (T) kanye nengxenye yamandla adonsela phansi ohlangothini oluqondile (wy) kuyasusana ngoba la mandla amabili anobukhulu obufanayo kodwa uhlangothi oluphambene.
Isibonelo 2. Into esesigodini. Ekuqaleni, into iyaphumula. Ngemva kokususwa, into iya kwesokudla nakwesobunxele, bese ibuyela endaweni yayo yokuqala. Ibhola liyahamba ukuze libuyele endaweni yalo yokuqala ngenxa yamandla adonsela phansi avelayo ohlangothini oluvundlile (wx). Ingxenye yamandla adonsela phansi ohlangothini oluqondile (wy) kanye namandla ajwayelekile (N) ziyahlukana ngoba amandla amabili anobukhulu obufanayo, kodwa isiqondiso siphambene.
Isibonelo 3. Ekuqaleni, into iphumule. Isikhungo samandla adonsela phansi siyisikhungo sento, kanti iphuzu lokusekela lisezansi lento ethintana nendiza eyisicaba. Ngemva kokuya kwesokudla, into iphakama iye kwesokudla. Uma isikhundla sesikhungo samandla adonsela phansi sisesesobunxele se-fulcrum, khona-ke into isengabuyela endaweni yayo yokuqala. Into ingabuyela endaweni yayo yokuqala ngenxa yomzuzu wamandla akhiqizwa amandla adonsela phansi. Kulokhu, iphuzu lokusekela lisebenza njenge-axis yokujikeleza. Ngokuphambene nalokho, uma into ishukunyiswa iye kwesobunxele, khona-ke into iphakanyiswe ngakwesobunxele. Uma indawo yesikhungo samandla adonsela phansi isese ngakwesokudla sendawo yokusekela, into isengabuyela endaweni yayo yokuqala.
Ezimweni ezifana nesibonelo sesi-3, izinto zisesekulinganisweni okuzinzile uma ngemva kokuphakanyiswa, isikhungo samandla adonsela phansi sento singadluli endaweni yokusekela. Uma ngemva kokuphakanyiswa ngakwesokudla, isikhungo samandla adonsela phansi sidlula indawo yokusekela, into isuka endaweni yayo yokuqala. Lesi yisibonelo sokulingana okungazinzile.
2. Ukulingana okungazinzile
Ukulingana akuzinzile uma into ekuqaleni ingashukumi ngenxa yamandla avelayo noma umzuzu wamandla osebenza entweni. Ngemva kokuhamba, into ayibuyeli endaweni yayo yokuqala, kodwa isuka endaweni yayo yokuqala.
Isibonelo 1. Into enganyakazi ekuqaleni ngenxa yokuphazamiseka. Ngemva kokuhamba, into iyaqhubeka nokunyakaza isuka endaweni yayo. Into isuka endaweni yayo yokuqala ngoba ngemva kokuhamba, indawo yesikhungo samandla adonsela phansi ingakwesokudla sendawo yokusekela. Lapho isikhungo samandla adonsela phansi singakwesokudla sendawo yokusekela, kuvela umzuzu wamandla ophumelayo, ophendula into isuke endaweni yayo yokuqala.
Isibonelo 2. Into ingaphezulu kwesiqongo ekuqaleni.
Ngemva kokususwa, into iyaqhubeka nokuhamba
kusuka endaweni yayo yokuqala. Into iyasuka endaweni yayo yokuqala ngenxa yokuba khona kwezingxenye zamandla adonsela phansi ohlangothini oluvundlile (w x ).
3. Ukulingana okungathathi hlangothi
Ukulingana okungathathi hlangothi uma ngemva kokuhamba ngenxa yokuphazamiseka, into ihlala endaweni yayo entsha. Izinto azibuyeli endaweni yazo yokuqala futhi izinto azisuki endaweni yokuqala.
Isibonelo 1: Ibhola liqala liphumule endaweni eyisicaba, liyahamba. Ngemva kokuyeka ukuhamba, ibhola lihlala endaweni yalo entsha. Ibhola aliphindeli endaweni yalo yokuqala noma alisuki endaweni yalo yokuqala.
Ngokusekelwe encazelweni engenhla, kungaphethwa ngokuthi:
Okokuqala, uma isikhungo samandla adonsela phansi sento singaphansi kwendawo yokusekela, into isesimweni sokulingana okuzinzile. Isibonelo, into ilenga ngentambo ku-buffer.
Okwesibili, uma isikhungo samandla adonsela phansi sento singaphezu kwephuzu lokusekela, ukulingana kwento kuyahambisana. Izinto zingaba zizinzile, izinto nazo zingaba zizinzile.
Okwesithathu, ukulingana kwezinto kuncike ekubunjweni kanye nosayizi wezinto. Izinto ezibanzi zizinzile kakhulu kunezinto ezibanzi.
Okwesine, ukulingana kwezinto kuncike ebangeni lesikhungo samandla adonsela phansi ukusuka endaweni yokusekela.
Uma isikhungo samandla adonsela phansi sikude nendawo yokusekela, khona-ke into isesimweni sokulingana okungazinzile. Ngokuphambene nalokho, uma isikhungo samandla adonsela phansi siseduze nendawo yokusekela, khona-ke ukulingana akuzinzile.
