Kahor intaadan soo saarin qaacidada muraayadda qaloocan, marka hore faham dhowr xeer oo loogu talagalay calaamadaha muraayadda qaloocan.
Xeerka Calaamadda Muraayadaha Concave
- Masaafada walxaha (yada)
Haddii shaygu uu ku yaal dhinaca muraayadda marka uu iftiinka iftiinku ka imanayo markaas masaafada shayga calaamadaysan togan.
- Masaafada sawirka (yada)
Haddii iftiin iftiin ahi uu hooska dhex maro markaas Masaafada hooska waxaa lagu calaamadeeyay togan (sawir dhab ah). Haddii sawirka aan la marin iftiin markaa Masaafada hooska calaamad taban (sawir dalwad ah).
- Dhererka diiradda (f)
Marka barta diiradda ee muraayadda la mariyo iftiin, markaas dhererka diiradda Muraayadda waxaa lagu calaamadeeyay togan. Taas bedelkeeda, haddii barta diiradda ee muraayadda aysan soo marin iftiinka iftiinka, markaas dhererka diiradda Muraayaddu waxay calaamad u tahay taban. Barta diiradda ee muraayadda qaloocan ma dhex marto iftiin sababtoo ah tan dhererka diiradda Muraayadaha indhaha ee wareegsan waa taban.
- Dhererka shayga (h)
Haddii shaygu uu ka sarreeyo dhidibka muraayadda qaloocan markaas dhererka shayga calaamad togan (shay toosan). Taas bedelkeeda, haddii shaygu uu ka hooseeyo dhidibka muraayadda qaloocan markaa dhererka shayga calaamad taban (shay rogrogma).
- Dhererka hooska (h')
Haddii sawirku ka sarreeyo dhidibka muraayadda qaloocan markaas dhererka hooska calaamad togan (sawir toosan). Haddii sawirku ka hooseeyo dhidibka muraayadda qaloocan markaa dhererka hooska calaamad taban (sawir rogrogmay).
- Weyneynta sawirka (m)
Haddii weynaynta sawirka > 1 markaas cabbirka sawirku wuu ka weyn yahay cabbirka shayga. Haddii weynaynta sawirku = 1 markaas cabbirka sawirku wuxuu la mid yahay cabbirka shayga. Haddii weynaynta sawirku < 1 markaas cabbirka sawirku wuu ka yar yahay cabbirka shayga.
Qaaciddada Muraayadda Koncave
Fiiri sawirka hoose. Waxaa jira laba iftiin oo la muujiyay oo u socda muraayad qaloocan, ka dibna iftiinka waxaa dib u celiya muraayad qaloocan.
Cinwaan:
s = masaafada walaxda, s' = masaafada sawirka, h = P P' = dhererka walaxda, h' = Q Q' = dhererka sawirka, F1 iyo F2 = barta diiradda ee muraayadda qaloocan.
Iftiinka P'AS, saddexagal P'AP wuxuu la mid yahay saddexagal Q'AQ. Sidaas darteed:
Iftiinka P'BR, saddexagal BF2A waxay la mid tahay saddexagalka Q'F2Q halkaas oo masaafada AB = dhererka shayga (h) iyo masaafada F2A = dhererka diiradda (f) ee muraayadda qaloocan. Sidaas darteed:
Dhinacyada bidix iyo midig ee isle'egyada 1 iyo 2 waa siman yihiin, sidaas darteed dhinacyada midig waa la siman yahay:
Labada dhinac ee isla'egta ku dhufo s':
Iyada oo ku saleysan xeerarka calaamadda muraayadda qaloocan, qaacidadan waxaa loo bedeli karaa sidan soo socota: Qaacidada muraayadda qaloocan, Haddii masaafada sawirka (yada) waxaa la siiyaa calaamad taban sababtoo ah hooska ma dhex maro iftiinka iyo iftiinka Dhererka diiradda (f) waxaa sidoo kale la siiyaa calaamad taban sababtoo ah barta diiradda ee muraayadda qaloocan iftiin kuma dhex maro (isbarbar dhig sawirka sameynta sawirka kore). Sida waafaqsan hadalkan, qaacidada muraayadda qaloocan ee kor ku xusan waxay isu beddeshaa:
Sharaxaad: s = masaafada shayga, s' = masaafada sawirka, f = dhererka diiradda.
Had iyo jeer xasuuso xeerka calaamadda muraayadda qaloocan marka aad isticmaaleyso qaacidadan si aad u xalliso dhibaatooyinka muraayadda qaloocan.
Weyneynta Sawirka (m)
Fiiri sawirka sameynta hooska shayga ee kor ku xusan. Saddexagalyada P'AP iyo Q'AQ waa isku mid, sidaa darteed waxaan soo saari karnaa xiriirka ka dhexeeya masaafada shayga iyo masaafada hooska iyadoo la adeegsanayo dhererka shayga iyo dhererka hooska:
Qaaciddadan waxaa mar kale loo qoray sida hoos ku xusan iyadoo lagu darayo m:
Macluumaadka:
m = weyneynta sawirka
h = dhererka shayga (togan haddii uu ka sarreeyo dhidibka muraayadda qaloocan ama shayga toosan)
h' = dhererka sawirka (togan haddii uu ka sarreeyo dhidibka muraayadda qaloocan ama sawirku uu toosan yahay)
s = masaafada shayga (togan haddii shayga la dhaafo iftiinka soo socda)
s' = masaafada sawirka (togan haddii sawirka la dhex mariyo iftiin iftiin leh ama sawir dhab ah)
