Xisaabi bedka qayb kasta.

A _A = (dherer)(ballac) = (4)(3) = 12

A _B = ½ (saldhig)(dherer) = ½ (6-4)(3) = ½ (2)(3) = (1)(3) = 3

A _C = ½ (saldhig)(dherer) = ½ (8-6)(3) = ½ (2)(3) = (1)(3) = 3

y _A = 1/2 (3) = 1.5

y _B = 3 – (1/3)(3) = 3 – 1 = 2

y _C = 3 – (1/3)(3) = 3 – 1 = 2

y _D = 3 + (1/2)(6-3) = 3 + (1/2)(3) = 3 + 1.5 = 4.5

x _A = 1/2 (4) = 2

x _B = 4 + (1/2)(6-4) = 4 + (1/2)(2) = 4 + 1 = 5

x _C = 6 + (1/2)(8-6) = 6 + (1/2)(2) = 6 + 1 = 7

Isku-dubbaridka xarunta cufisjiidadka ee dhidibka y:

1. Waa maxay xarunta cufisjiidadka (COG) ee shay?
   • Jawaab: Xarunta cufisjiidadka waa barta shayga lagu tirin karo inuu ku shaqeeyo. Waa celceliska goobta miisaanka shaygu ku yaal.
2. Sidee ayuu COG uga duwan yahay xarunta cufnaanta?
   • Jawaab: In kasta oo COG iyo xarunta cufkuba ay tilmaamayaan celceliska goobta miisaanka iyo cufnaanta siday u kala horreeyaan, way kala duwanaan karaan haddii goobta cufisjiidadka ee ku shaqeysa shayga aysan isku mid ahayn. Si kastaba ha ahaatee, inta badan xaaladaha dhabta ah ee Dunida, si wax ku ool ah ayay isku mid yihiin.
3. Maxay muhiim u tahay fahamka COG ee naqshadeynta baabuurta?
   • Jawaab: Goobta uu ku yaallo COG waxay saameysaa xasilloonida gaariga. COG hooseeya wuxuu ka dhigi karaa gaariga mid aan u badnayn inuu rogrogo oo guud ahaan xasilloon, gaar ahaan inta lagu jiro leexashada ama dhaqdhaqaaqyada degdegga ah.
4. Sidee bay miisaanka si kala duwan ugu qaybinaysaa gaadhi ama qaab-dhismeedku u saameeyaa xaruntiisa cufisjiidadka?
   • Jawaab: Ku darista miisaanka dusha sare ee dhismaha ama gaariga waxay kordhin doontaa COG-giisa, taasoo ka dhigaysa mid aan xasilloonayn. Taas beddelkeeda, ku darista miisaanka salka hoose ama salka waxay hoos u dhigi kartaa COG-ga, taasoo xoojinaysa xasilloonida.
5. Haddii shay si xor ah looga laalaado meel, xaggee bay COG-giisu ku jiri doontaa?
   • Jawaab: COG-ga shayga la laalay wuxuu si toos ah ugu hoos jiri doonaa barta la laalay, isagoo si toosan ula jaanqaadaya barta la laalay sababtoo ah xoogga cufisjiidadka.
6. Xarunta cufisjiidadka shayga ma ka baxsan kartaa xuduudaha walxaha ee shayga?
   • Jawaab: Haa, COG-gu wuxuu ku yaalli karaa meel ka baxsan walaxda dhabta ah ee shayga. Tusaale caadi ah waa giraan ama dhululubo godan; COG-giisu wuxuu ku yaal bartamaha, meel aan lahayn wax walxo ah.
7. Maxay dadka lugeeya xarigga cidhiidhiga ah badanaa u isticmaalaan tiirar dhaadheer?
   • Jawaab: Usha dheer waxay fidisaa ballaca waxtarka leh ee saldhiggooda waxayna hoos u dhigtaa COG-gooda. Labadan saameynba waxay xoojiyaan xasilloonidooda iyo dheelitirnaantooda iyagoo ku socda xarigga cidhiidhiga ah.
8. Sidee ayay qaabka iyo qaybinta cufka ee shay u saameeyaan COG-giisa?
   • Jawaab: COG-gu wuxuu had iyo jeer u janjeeraa meelaha shayga leh cuf weyn. Tusaale ahaan, shay halkaas oo cuf badan uu ku urursan yahay hal dhinac, COG-gu wuxuu u dhowaan doonaa dhammaadkaas.
9. Sidee baad si tijaabo ah ugu ogaan kartaa COG-ga shay fidsan oo aan qaab lahayn, sida kartoon laga sameeyay?
   • Jawaab: Mid ka mid ah habku waa in shayga lagu laalo hal dhibic oo la sawiro xariiq toosan oo hoos uga soo dhacda barta laalaada. Kadib, shayga laga laalo meel kale oo la sawiro xariiq toosan oo kale. Barta ay xariiqyadani isku xirmaan waa COG.
10. Bayoomakiinikyada aadanaha, maxay COG muhiim u tahay?

• Jawaab: Fahmidda COG-ga aadanaha waa mid muhiim u ah hawlaha sida socodka, orodka, iyo boodboodka. Waxay saamaysaa dheelitirkayaga, xasilloonida, iyo farsamooyinka dhaqdhaqaaqa. COG-ga aadanaha badanaa wuxuu ku yaal agagaarka gobolka xuddunta, laakiin tani way isbeddeli kartaa marka jirka iyo dhaqdhaqaaqa la eego.
