Indlela abale isibalo lodonga?

Ukulungiswa in the efulethini - kuba enzima futhi zibiza. Okubaluleke nakakhulu kangakanani kahle ukubala lemali edingekayo ukwakhiwa kanye izinto kokuqeda. Lokhu kusiza ukugwema ekuthengeni izinto ezingadingekile, futhi isidingo kabusha uthenge lezo noma ezinye izinto akunakwenzeka ukuba ziyaphuma. Ikakhulukazi eziningi izinkinga ezingavela kanye lodonga, njengoba kukhona ezinye umehluko wemisindo nemiqondo yamagama, ngaphandle okuyinto akunakwenzeka ukuphendula umbuzo kanjani ukubala inani lodonga ku egumbini.

Ukuze wenze lokhu kumelwe acabangele eziningi nemingcele ngesisekelo okuyinto ukubala wenziwa. Okokuqala, kudingeka sazi azungezwe we egumbini. Bala it silula, vele ungeze sonke ubude phakathi kwezindonga. Ngokwesibonelo, ukuthatha ejwayelekile Igumbi usayizi: 3x4 m Ngakho, siba 2 izindonga 3 metres uphinde uthele kancane 2 kuya ku-4 3x2 + 4x2 = 14 m sibalo elandelayo, okuyinto nje odinga ukukwazi - ukuphakama ibalwa yophahla olungaphakathi ... Lo mqondo kuhlanganisa ukuphakama langempela isinyathelo ophahleni okwakhiwe uma sangemuva akuyona ethafeni, noma nge isibonelo esihle, ibizwa ngokuthi umbiko, futhi ungakhohlwa ukungeza 10 cm ingxenye kwewebhu. Lapho Uphahla lwangaphakathi imitha emithathu nesithombe esikhulu, umbiko cm 60, ukuphakama langempela ophahleni ilingana 3 + 0,6 + 0,1 = 3,7 m.

Ukuze uphendule ngokunembile umbuzo kanjani ukubala inani iphepha lokunamathisela odongeni, odinga ukukwazi hhayi kuphela nemingcele egumbini, kodwa futhi ubukhulu umqulu lodonga. osayizi Standard imiqulu zimi kanje: nobubanzi 52, 53 noma 60 cm, ubude mayelana 10,05 m Nokho, zikhona ezinye izinhlangothi .. Nalapha futhi, isibonelo, ukuthatha ububanzi umqulu 52 cm kanye nobude 10,05 m. Manje sidinga ukuthola amaqoma amangaki indlela egcwele bands etholakala roll olulodwa. Roll obuphelele lihlukaniswe by ukuphakama ebalisisiwe yophahla olungaphakathi: 10.05 / 3.7 = 2.7. Imidwebo uthole ezimbili kuphela, waphetha lesi sibalo ohlangothini ezincane njalo, ngoba sinesithakazelo kuphela iwebhu yonke.

Okulandelayo udinga ukubala zingaki kudingeka Imidwebo egumbini. Kulula ukuqonda ukuthi lokhu kuyadingeka ukuze uhlukanise azungezwe ububanzi roll: 14 / 0.52 = 26.9. Lesi sibalo babanjwa, uma kungenjalo ahlale neokleennye uchastochki. Lokho, egumbini lethu kudingeka 27 imidwebo.

Kanjani ukubala lodonga ngesisekelo zonke lezi idatha? Izimo zethu zihluke kakhulu ngokusobala, inani izindwani, okuyinto kudingeka egumbini Ukugoqa, kufanele ihlukaniswe inani elifanayo roll ngamunye: 27/2 = 13.5. Njengoba lodonga ukuthengisa lonke roll kuphela, kule nombolo babanjwa - 14 imiqulu. Ngaphezu kwalokho, lodonga kungcono ukuthatha ngemajini encane. Ngidinga ukuthenga eyodwa - amabili imiqulu engaphezu kuka wangena izibalo.

Yileyo impendulo yombuzo othi kanjani ukubala inani lodonga. Nokho, kukhona ezinye umehluko wemisindo nemiqondo yamagama ukuthi bayakufanelekela kokukhuluma. Okokuqala, cishe uye waphawula ukuthi akuthathwa amafasitela kanye lemigubazi kulezi izibalo. Lokhu kwenziwa ngoba okufanayo, okusenza umqulu ezengeziwe. Ngenxa yalesi kungenzeka ukusebenzisa umqulu olulodwa ilebula test ukuze baqeqeshwe ukuhlanganisa umdwebo. Futhi kukhona njalo ingozi engaqondile konakalisa strip.

Kungcono ukuthatha umqulu ezingaphezu kuka-ke funa sangemuva efanayo. By the way, kulesi simo ngempela kufanele ugcine ilebula okungenani owodwa kusukela lodonga bakwazi ukubukela uchungechunge. Iqiniso lokuthi omunye futhi sangemuva ofanayo uchungechunge ezahlukene kungahluka ezibonakalayo ngombala.

Uma ufundisisa isihloko, kuba sobala ukuthi umbuzo kanjani ukubala inani iphepha lokunamathisela odongeni, ukukhetha uhlobo oluthile lodonga kwenzelwe nje theory. Phela, asipheli yokuthi ukhetha sangemuva usayizi ethile umbiko othize. Ngakho, izibalo kungase kube okungaqondile.

Nokho, ukwenza ukubala enjalo Kusafanele udlulele okungenani ibe umqondo anolaka mayelana nenani iphepha lokunamathisela odongeni, ukuthi kungadingeka. Nale inombolo usazoba kube lula ukuyisebenzisa. Futhi ngokukhetha uhlobo oluthile, ungakwazi masinyane wenze zokubala kabusha.

Sithemba ukuthi uthola impendulo ewujuqu umbuzo kanjani ukubala inani lodonga.
