10 Tusaalooyin Su'aalo Cadaadis ah
1. Cufka iyo mugga afarta baloog ee hoose waa isku mid, sidaa darteed cadaadiska ugu yar ee dhulka waxaa sameeya lambarka shayga...
A. Aniga
B. II
C. III
D. IV
Dood
Qaacidada cadaadiska:
P = F / A
Iyada oo lagu saleynayo qaacidadan, waxaa lagu soo gabagabeynayaa in cadaadiska (P) uu si toos ah ugu dhigmayo xoogga (F) iyo inuu si liddi ah ugu dhigmayo aagga dusha sare (A). Taas macnaheedu waa haddii xooggu ka weyn yahay, cadaadisku sidoo kale wuu ka weyn yahay, haddii aagga dusha sare uu ka weyn yahayna, cadaadisku sidoo kale wuu ka yar yahay.
Iyada oo ku saleysan sawirka, meesha ugu weyn ee dusha sare ee la xiriirta dabaqa waa shayga III si shaygani uu cadaadiska ugu yar ku saaro dabaqa.
Jawaabta saxda ah waa C.
2. Haddii cufka afarta saddexagal ee hoose uu isku mid yahay, cadaadiska ugu badan ee aagga cadaadiska waxaa lagu tilmaamayaa sawirka...

Qaacidada cadaadiska:
P = F / A = w / A
Macluumaad: P = cadaadis, F = xoog, w = cufisjiidadka, A = bedka dusha sare ee taabanaya dabaqa.
Iyada oo lagu saleynayo qaacidadan, waxaa la soo gabagabeyn karaa in cadaadisku uu si toos ah ugu dhigmayo cufisjiidadka iyo inuu si liddi ku ah ugu dhigmayo bedka dusha sare ee taabanaya dabaqa. Sidaa darteed, cufisjiidadka badan, ayaa cadaadiska badanaya, iyo baaxadda dusha sare ee shay yar oo taabanaya dabaqa, ayaa cadaadiska weynaya.
Haddii cufka afarta saddexagal ay isku mid yihiin, markaa xoogga cufisjiidadka ee dhammaan afarta saddexagal waa isku mid. Sidaa darteed, cadaadisku wuxuu ku xiran yahay bedka dusha sare ee la xiriira dabaqa, halkaas oo bedka ugu yar uu leeyahay cadaadiska ugu badan.
Jawaabta saxda ah waa B.

Dardargelinta cufisjiidadka awgeed (g) = 10 m/s2
Cufisjiidadka (w) = mg = (75 kg)(10 m/s2) = 750 kg m/s2 = 750 Newton
Bedka dusha sare ee salka sanduuqa (A) = 6 mitir x 5 mitir = 30 mitir oo laba jibbaaran
La weydiiyay: Cadaadiska uu saarayo qaybta hoose ee sanduuqa
Jawaab:
Cadaadiska uu sameeyo qaybta hoose ee sanduuqa:
P = F/A = w/A = 750/30 = 25 N/m2

7. Sanduuq kartoon ah oo ay ku jiraan cambe ayaa miisaankiisu yahay 24 kg waxaana la dhigayaa dabaqa cabbirkiisuna waa sida sawirka ka muuqata (g = 10 m/s).2) Cadaadiska uu kartoonku dhulka ku hayo waa….
A. 600 N/m2
B. 1000 N/m2
D. 2400 N/m2
Dood
Waa la ogyahay in:
Cuf (m) = 24 kg
Dardargelinta cufisjiidadka awgeed (g) = 10 m/s2
Miisaanka (w) = mg = (24 kg)(10 m/s)2) = 240 kg m/s2 = 240 Newton
Bedka dusha sare ee taabanaya dabaqa (A) = 1 m x 0,4 m = 0,4 m2
La weydiiyay: Cadaadiska uu kartoonku dhulka ku hayo
Jawaab:
Qaacidada cadaadiska:
P = F / A = w / A
Sharaxaadda qaacidada: P = cadaadis, F = xoog, w = cufisjiidadka, A = bedka dusha sare
Cadaadiska uu kartoonku dhulka ku hayo:
P = 240 N / 0,4 m2 = 600 N/m2

8. Afar baloog oo isku mid ah oo isku cuf ah ayaa la dhigay isla dabaqa booska lagu muujiyay sawirka. Cadaadiska ugu badan ee dabaqa soo maray waxaa lagu muujiyay sawirka...
Dood
Qaacidada cadaadiska :
P = F / A = w / A
Macluumaadka: P = cadaadis, F = xoog, w = cufisjiidadka, A = bedka dusha sare.
Iyada oo lagu saleynayo qaacidada cadaadiska, waxaa lagu soo gabagabeynayaa in cadaadisku uu la mid yahay xoogga iyo inuu la mid yahay bedka dusha sare. Inta xooggu sii badanayo, ayuu cadaadiska sii badanayaa. Inta baaxadda dusha sare ay sii weynaanayso, ayuu cadaadiska sii yaraanayaa.
Cufnaanta baloogyada waa isku mid, sidaa darteed miisaankoodu waa isku mid. Sidaa darteed, xaddiga cadaadiska ee dhibaatada kor ku xusan waxaa lagu go'aamiyaa aagga dusha sare ee la xiriira dabaqa (aagga saldhigga). Cadaadiska ugu badan ee uu sagxadda la kulmo waxaa sababa baloogga leh aagga saldhigga ugu yar.
Bedka dusha sare ee baloogga A = (2 cm)(4 cm) = 8 cm2
Bedka dusha sare ee baloogga B = (4 cm)(4 cm) = 16 cm2
Bedka dusha sare ee baloogga C = (4 cm)(3 cm) = 12 cm2
Bedka dusha sare ee saddex-jibbaaran D = (3 cm)(3 cm) = 9 cm2
Jawaabta saxda ah waa A.

Cufnaanta baloogyada waa isku mid, sidaa darteed miisaankoodu waa isku mid. Sidaa darteed, xaddiga cadaadiska ee dhibaatada kor ku xusan waxaa lagu go'aamiyaa bedka dusha sare ee baloogga ee la xiriira dabaqa (bedka salka). Cadaadiska ugu yar ee uu sagxadda la kulmo waxaa sababa baloogga leh bedka saldhigga ugu weyn.
Bedka dusha sare ee baloogga A = (2 cm)(2 cm) = 4 cm2
Bedka dusha sare ee baloogga B = (1 cm)(3 cm) = 3 cm2

Dood
Cufka baloogyada waa isku mid sidaa darteed culeyska baloogyada waa isku mid. Cadaadiska ugu yar ee ku yimaada diyaaradda cadaadiska waxaa lagu go'aamiyaa inuu sabab u yahay alwaaxa leh aagga saldhigga ugu weyn.
