Maqaal ku saabsan Astaamaha sawirka oo ay samaysay muraayadda convex
Masaafada shayga ayaa ka yar dhererka diiradda ee muraayadda qaloocan (do < f)
Iyada oo lagu saleynayo xisaabinta sameynta sawirka iyadoo la adeegsanayo muraayadda qaloocan , waxaa lagu soo gabagabeyn karaa in haddii masaafada shayga (same) ay ka yar tahay dhererka diiradda (f), sifooyinka sawirka waa:
– Macnaheedu waa iftiinka iftiinku ma dhex maro sawirka sababtoo ah sawirku wuxuu ka dambeeyaa muraayadda qaloocan
- Toosan
– Inta shaygu ka fog yahay muraayadda qaloocan, ayaa cabbirka sawirku sii yaraanayaa
– Inta shaygu ka fog yahay muraayadda qaloocan, ayay sawirka ka yar tahay muraayadda qaloocan.
Masaafada shayga waxay la mid tahay dhererka diiradda ee muraayadda qaloocan (do = f)
Iyada oo lagu saleynayo xisaabinta sameynta sawirka ee muraayadda qaloocan , waxaa lagu soo gabagabeyn karaa in haddii masaafada shaygu ay la mid tahay dhererka diiradda muraayadda, sifooyinka sawirka waa:
– Macnaheedu waa iftiinka iftiinku ma dhex maro sawirka sababtoo ah sawirku wuxuu ka dambeeyaa muraayadda qaloocan
- Toosan
- La yareeyay (Cabbirka sawirka = ½ jibaar cabbirka shayga)
– Masaafada sawirku way ka yar tahay masaafada shayga (masaafada sawirka = ½ jeer masaafada shayga)
Masaafada shayga ayaa ka weyn dhererka diiradda waxayna ka yar tahay gacanka qalooca muraayadda qalooca leh (f < do < R)
Iyada oo lagu saleynayo xisaabinta sameynta sawirka iyadoo la adeegsanayo muraayadda qaloocan , waxaa lagu soo gabagabeyn karaa in haddii shaygu uu u dhexeeyo barta diiradda saaran iyo gacanka qalooca, sifooyinka sawirka waa:
– Macnaheedu waa iftiinka iftiinku ma dhex maro sawirka sababtoo ah sawirku wuxuu ka dambeeyaa muraayadda qaloocan
- Toosan
– Cabbirka sawirku wuu ka yar yahay cabbirka shayga
– Inta shaygu ka fog yahay muraayadda qaloocan, ayay sawirku ka fog yahay muraayadda qaloocan.
Masaafada walaxda waxay la mid tahay gacanka qalooca muraayadda qalooca leh (do = R)
Iyada oo lagu saleynayo xisaabinta sameynta sawirka iyadoo la adeegsanayo muraayadda qaloocan , waxaa lagu soo gabagabeyn karaa in haddii masaafada shayga ay la mid tahay gacanka qalooca, sifooyinka sawirka waa:
– Macnaheedu waa iftiinka iftiinku ma dhex maro sawirka sababtoo ah sawirku wuxuu ka dambeeyaa muraayadda qaloocan
- Toosan
- La yareeyay (cabbirka sawirka = 1/3 jibaar cabbirka shayga)
– Masaafada sawirku way ka yar tahay masaafada shayga (Masaafada sawirka = 1/3 jeer masaafada shayga)
Masaafada walaxda ayaa ka weyn gacanka qalooca muraayadda qalooca leh (samee > R)
Iyada oo lagu saleynayo xisaabinta sameynta sawirka ee muraayadda qaloocan , waxaa lagu soo gabagabeyn karaa in haddii masaafada walaxdu ay ka weyn tahay gacanka qalooca muraayadda, sifooyinka sawirka waa:
– Macnaheedu waa iftiinka iftiinku ma dhex maro sawirka sababtoo ah sawirku wuxuu ka dambeeyaa muraayadda qaloocan
- Toosan
– Cabbirka sawirku wuu ka yar yahay cabbirka shayga
– Masaafada sawirku way ka yar tahay masaafada shayga (sawirku wuxuu u dhow yahay muraayadda, shayguna wuu ka fog yahay muraayadda)
- Noocee sawir ah ayaa sameeya muraayad qaloocan?
Muraayadaha wareegsan waxay had iyo jeer sameeyaan sawir casri ah, la dhimay, oo toosan.
- Sidee buu booska shay u saameeyaa booska sawirka ee muraayadda qaloocan?
Meel kasta oo shaygu ku yaal, sawirka ay samaysay muraayad qaloocan ayaa had iyo jeer ku yaal inta u dhaxaysa muraayadda iyo diiradda.
- Maxay sawirrada ay sameeyaan muraayadaha qaloocan u yareeyaan?
Sawirradu way yaraadaan sababtoo ah fallaaraha iftiinka way kala duwan yihiin marka la milicsado. Natiijo ahaan, waxay u muuqdaan inay ka yimaadaan meel muraayadda uga dhow shayga dhabta ah, taasoo keenta in sawirku u muuqdo mid ka yar shayga.
- Sidee buu weyneynta 'm' ee muraayadda qaloocan ula xiriiraa masaafada sawirka iyo walxaha?
Weyneynta muraayadda qaloocan waxaa lagu bixiyaa saamiga dhererka sawirka iyo dhererka shayga, kaas oo sidoo kale la mid ah saamiga masaafada sawirka 'v' iyo masaafada shayga 'u'. Muraayadda qaloocan, 'm' waxay la mid tahay -v/u.
- Waa maxay muhiimadda calaamadda taban ee qaacidada weynaynta ee muraayadaha qaloocan?
Calaamadda taban waxay muujinaysaa in sawirku yahay mid casri ah oo toosan, maadaama sawirrada ay sameeyeen muraayadaha qaloocan ay had iyo jeer yihiin kuwo casri ah oo toosan.
- Sidee dhererka diiradda 'f' ee muraayadda qaloocan ula xiriiraa gacanka qalooca 'R'?
Dhererka muraayadda qaloocan waa kala bar gacanka qaloocan, sidaa darteed 'f' wuxuu la mid yahay R/2. Muraayadda qaloocan, dhererka diirka waxaa loo qaataa mid taban, taasoo tilmaamaysa in diiraddu ay tahay mid casri ah.
- Masaafada shayga ee 'u' ma togan tahay mise taban tahay muraayadda qaloocan?
Muraayadda qaloocan, masaafada shayga ee 'u' waxaa loo qaataa mid taban. Xeerkani wuxuu ka dhashay xaqiiqda ah in shayga had iyo jeer la dhigo muraayadda horteeda.
- Waa maxay isle'egta muraayadda ee muraayadda wareegsan sideese looga soo qaatay?
Isle'egta muraayadda waa 1/v + 1/u = 1/f. Waxaa laga soo qaatay joomatari ee muraayadaha wareegsan, iyadoo la tixgelinayo xiriirka ka dhexeeya masaafada shayga, masaafada sawirka, iyo dhererka diiradda.
- Maxaa ku dhacaya sawirka ay samaysay muraayad qaloocan marka shaygu u soo dhawaado muraayadda?
Marka shaygu u soo dhawaado muraayadda, sawirku sidoo kale wuu u soo dhawaadaa muraayadda, laakiin had iyo jeer wuu ka yar yahay shayga wuxuuna ku sii jiraa inta u dhaxaysa tiirka iyo diiradda.
- Maxaa muraayadaha qaloocan loogu isticmaalaa muraayadaha gadaal ee baabuurta?
Muraayadaha wareegsan ayaa badanaa loo isticmaalaa muraayadaha gadaal laga daawado sababtoo ah waxay sameeyaan sawir yar, taasoo siinaysa aragti ballaaran. Tani waxay u oggolaanaysaa darawalka inuu arko jawiga gadaasha gaariga, taasoo kor u qaadaysa amniga.
