Kodi ma angle a R a square chubu amatchulidwa bwanji mumtundu wa dziko?

Ngongole ya R mu chubu lalikulu ndi njira yosinthira pamphambano za ndege ziwiri, zomwe nthawi zambiri zimakhala theka la mainchesi apakati pa ngodya yopindika ya arc R.Mtengo wa arc R yokhotakhota nthawi zambiri imakhala 1.5 ~ 2.0 kuchulukitsa kwa chitoliro.Kukula kwa ngodya ya R kumatsimikiziridwa molingana ndi makulidwe a khoma la chubu lalikulu.Mbali ya R imagawidwa mkatikati mwa R angle ndi R yakunja.R mkati nthawi zambiri amakhala 1.5 ~ 2 nthawi makulidwe a khoma.Machubu achitsulo a square okhala ndi ma angle osiyanasiyana a R amathanso kupangidwa malinga ndi zomwe wogwiritsa ntchito amafuna.
Mwachitsanzo, paipi yachitsulo yamakona anayi yokhala ndi arc R, A=1.0MM, diagonal=1.15MM, mumadziwa bwanji ngodya ya R?Ngati ndi chitoliro chachitsulo chokhala ndi arc, kodi njira yowerengera ndiyofanana?Rectangle ili ndi kutalika kwa A ndi m'lifupi mwa B, ndi diagonal ya C, ndipo utali wa ngodya zinayi arcs R ndi wofanana.Weretsani kukula kwa R motsatira njira iyi: (C/2-R) ^ 2=(A/2-R) ^ 2+(B/2-R) ^ 2 C ^ 2/4-CR+R ^ 2 =A ^ 2/4-AR+R ^ 2+B ^ 2/4-BR+R ^ 2 4R ^ 2-4 (A+BC) R+(A ^ 2+B ^ 2-C ^ 2)=0 .
Tiyenera kutsindika apa kuti mbali ya R ya chubu yotsika ya rectangular sikutanthauza arc, koma ngodya yapakati.Arc imatanthawuza gawo pa circumference, ndipo mbali yophatikizidwa ya mzere pakati pa malekezero awiri a arc ndi pakati ndi ngodya yapakati.Popeza kuti kuzungulira kwa bwalo ndi 2 π R ndipo ngodya yake yapakati ndi 2 π, utali wa arc wolingana ndi ngodya yapakati ndi 2 π R/2 π=R.Chifukwa chake, kutalika kwa arc kolingana ndi ngodya iliyonse yapakati (radian unit) = aR imapezedwa.Njira zoyezera ndi zida za square chubu R angle imaphatikizapo R gauge ndi projector.The R gauge itha kugwiritsidwa ntchito pazochindikira, purojekitala ya mfundo zabwino, ndi CMM pazofunikira zazikulu.
