Isibonelo: Intambama ye-D’Alembert
Iyunithi elilodwa phezulu ngemuva kokuhlulwa, iyunithi elilodwa phansi ngemuva kokuwina, kokubomvu kukho konke ukujikeleza okulikhulu. Uhlelo olunesizotha kunazo zonke, nentengo yalesi sizotha.
Iseshini elingisiwe ye-D’Alembert yokujikeleza okungu-100 ngo-$5 iyunithi. Inani elibhejwayo labuyela ku-$5 izikhathi ezinhlanu, lanyuka kancane laya ku-$80 ngesikhathi sobunzima, futhi laphela ku-$55 iseshini ilahlekelwe ngu-$40. Uhlelo oluzwakala njengokulinganisela kodwa olungesikho.
Hamba nohlelo
Ukuhlulwa kunyusa isinyathelo esisodwa. Ukuwina kubuyisela emuva isinyathelo esisodwa.
Amanani abhejwayo nemiphumela kungamayunithi okubheja okuyisisekelo.

NgesiFulentshi: rouge.Funda konke →. Ngemuva kokuhlulwa engeza iyunithi; ngemuva kokuwina susa eyodwa, ungalokothi wehle ngaphansi kweyodwa. Umbono, u-d’Alembert angazange awuphakamise kodwa asolwa ngawo, ukuthi ukuwina nokuhlulwa kuyalingana, ngakho kuzo zonke izinhlangano zokuhlulwa okukodwa nokuwina okukodwa siphambili ngeyunithi. Izibalo zithi okubomvu kuwina ku-48.65% yokujikeleza, ngakho ukuhlulwa kudlula ukuwina ngokucishe kube kukodwa kokungamashumi amane, futhi inani elibhejwayo linyuka kancane ngokuhamba kwesikhathi.

Inani elibhejwayo lenyuka laya ku-$20 ngesikhathi sochungechunge lokuhlulwa kathathu, labuyela ku-$5 ekujikelezeni 18, lenyuka laya ku-$25 ekupheleni kwale ngxenye. Isamba ngu-+$20. Inhlangano ngayinye yokuhlulwa nokuwina yanika iyunithi njengoba kuthenjisiwe; ukuhlulwa okwengeziwe kwazidla lezo yunithi. Kuzwakala njengepompi elihamba kancane elivamise ukusebenza.
Ukujikeleza 31–65
Isikhathi sobunzima. Okubomvu okuyishumi nantathu uma kuqhathaniswa nokungekhona okubomvu okungamashumi amabili nambili, kuhlanganise nochungechunge lokuhlulwa okuyisikhombisa. Kusuka ku-$5 ekujikelezeni 41 inani elibhejwayo lakhuphuka iyunithi elilodwa ngesikhathi laya ku-$80, futhi ukulahlekelwa ngakunye kuka-$75 kwahlehlisa ukuwina okuyishumi nanhlanu kuka-$5 kwangaphambili. Isamba ngu-−$485 kule ngxenye; isamba esiqhubekayo −$465. Akukho okwamangalisayo okwenzeka ekujikelezeni okukodwa; ukunyuka kancane kwakwenza lokho.

Ukujikeleza 66–100
Okubomvu okungamashumi amabili uma kuqhathaniswa nokungekhona okubomvu okuyishumi nanhlanu, inani elibhejwayo lehla kusuka ku-$80 libheke ku-$55 ngezinyathelo zika-$5. Ukuwina ngakunye ngenani eliphezulu kwabuyisa imali yangempela: ukuwina kuka-$75 ngemuva kokulahlekelwa ngu-$70 kuyinhlangano enika u-+$5, kodwa inhlangano inkulu. Isamba ngu-+$425 kule ngxenye; ekugcineni −$40.
Izibalo
Inani elibhejwayo elimaphakathi cishe ngu-$37, ngakho isamba esibhejiwe cishe ngu-$3,670 uma kuqhathaniswa no-$500 womuntu obheja u-$5 olinganayo njalo.

Lokho okuboniswa yiseshini
I-D’Alembert iyiphutha lomgembuli elibhalwe njengomthetho wokubheja: icabanga ukuthi ukuwina nokuhlulwa kuzolingana ngokushesha okwanele ukuze inani elibhejwayo libuyele phansi. Kuyalingana ekuhambeni kwesikhathi eside ngokuhlanjululwa, hhayi ngokulungiswa, futhi inani elibhejwayo alinasizathu sokubuyela eyunithini eyodwa. Wuhlelo oluhamba kancane olungenalo iwa, futhi ukuhamba kancane yikho okwenza abadlali bakholwe kulo.

Imibuzo
Akuvamile. Inani elibhejwayo lenyuka ngeyunithi elilodwa ekuhlulweni ngakunye, aliphindwa kabili, ngakho kudinga uchungechunge olude kakhulu lobunzima ukuze lifike emkhawulweni.
Yebo, futhi umkhawulo uluguqula lube ukubheja inani elilinganayoisuUkubheja ngenani elilodwaUkubheja inani elifanayo kukho konke ukujikeleza. Isisekelo okuqhathaniswa naso konke ukwenyuswa kwenani.Funda konke → emkhawulweni ngemuva kobunzima. Noma yimuphi umkhawulo ulungile; awukho oguqula inzuzo yekhasino.
Ngo-1754 wathi umsila (tails) uba namathuba amakhulu ngemuva kochungechunge lwamakhanda (heads). Abagembuli ababevumelana naye baqamba uhlelo ngaye. Ngabe waba namahloni.
Okokuhlekisa
Uhlelo olunesizotha kunazo zonke. Lunyuka kancane esikhundleni sokuwa.
