Maqaal ku saabsan Isle'egta muraayadaha isku soo ururaya (convex)
Kahor intaadan baran isle'egta muraayadda qaloocan, faham xeerarka calaamadaha ee muraayadda qaloocan ee hoose.
Xeerarka calaamadda ee muraayadda qaloocan
– Masaafada shayga (samayn)
Haddii shay la dhex mariyo iftiin, markaas masaafada shayga waa togan.
– Masaafada sawirka (di)
Haddii iftiinka iftiinku uu dhaafo sawirka, markaas masaafada sawirku waa togan tahay (sawir dhab ah). Haddii iftiinka iftiinku uusan dhex marin sawirka, masaafada sawirku waa taban tahay (sawir dalwaddeed).
– Dhererka diiradda (f)
Marka iftiinka iftiinka uu dhex maro barta diiradda ee muraayadda, dhererka diiradda ee muraayadda waa togan. Taas beddelkeeda, haddii iftiinka iftiinku uusan dhaafin barta diiradda ee muraayadda, dhererka diiradda ee muraayadda waa taban. Barta diiradda ee muraayadda qaloocan waxaa lagu dhex maraa iftiinka iftiinka. Sidaa darteed, dhererka diiradda ee muraayadda qaloocan waa togan.
– Dhererka shayga (ho)
Haddii shaygu ka sarreeyo dhidibka ugu muhiimsan, markaas dhererka shaygu wuxuu calaamad u yahay togan (shaygu waa toosan yahay). Taas beddelkeeda, haddii shaygu ka hooseeyo dhidibka ugu muhiimsan ee muraayadda qaloocan, dhererka shaygu waa taban (shaygu waa la rogay).
– Dhererka sawirka (hi)
Haddii sawirku ka sarreeyo dhidibka ugu weyn, dhererka sawirku waa togan yahay (sawirku waa toosan yahay). Haddii sawirku ka hooseeyo dhidibka ugu weyn, dhererka sawirku waa taban yahay (sawirku waa rogrogmay).
– Weyneynta sawirka (m)
Haddii weynaynta sawirka > 1, markaas cabbirka sawirku wuu ka weyn yahay cabbirka shayga. Haddii weynaynta sawirka = 1, markaa cabbirka sawirku wuxuu la mid yahay cabbirka shayga. Haddii weynaynta sawirku tahay < 1, cabbirka sawirku wuu ka yar yahay cabbirka shayga.
Isle'egta muraayadda qaloocan
s = do = masaafada shayga, s' = di = masaafada sawirka, ho = P P' = dhererka shayga, hi = Q Q' = dhererka sawirka, F 1 iyo F 2 = barta diiradda ee muraayadda isku soo ururaysa.
Saddexagalka P'AP wuxuu la mid yahay saddexagalka Q'AQ. Sidaa darteed:
Saddex-xagalka BF 2 A = Q'F 2 Q halkaas oo masaafada AB = dhererka shayga (h) iyo masaafada F2A = dhererka diiradda (f) ee muraayadda qaloocan. Sidaa darteed:
do = masaafada shayga (togan haddii shayga uu dhex maro iftiinka)
di = masaafada sawirka (togan haddii sawirka uu dhex maro iftiinka ama sawirku uu yahay mid dhab ah)
f = dhererka diiradda (togan haddii barta diiradda ee muraayadda qaloocan ay dhex marto iftiinka iftiinka)
Had iyo jeer xasuuso xeerarka calaamadaha muraayadaha wareegsan marka aad isticmaaleyso isla'egtan si aad u xalliso dhibaatada muraayadaha wareegsan.
Weyneynta sawirka (m)
U fiirso sameynta sawirka kore. Sida saddexagalada 'PAP iyo QAQ', waxaan soo saari karnaa xiriirka ka dhexeeya masaafada shayga iyo masaafada sawirka iyadoo la adeegsanayo dhererka shayga iyo dhererka sawirka:
Isle'egta kore waxaa dib loogu qori karaa sida hoos ku xusan iyadoo lagu darayo calaamadda m:
m = weyneynta sawirka
ho = dhererka shayga (togan haddii shaygu ka sarreeyo dhidibka ugu weyn ee muraayadda qaloocan ama shaygu uu toosan yahay)
hi = dhererka sawirka (taban haddii sawirku ka hooseeyo dhidibka ugu weyn ee muraayadda qaloocan ama sawirka la rogay)
do = masaafada shayga (togan haddii shayga uu dhex maro iftiinka)
di = masaafada sawirka (togan haddii sawirka la mariyo iftiinka ama sawirku yahay mid dhab ah)
