Yaya aka kayyade kusurwar R na bututun murabba'i a cikin ma'aunin ƙasa?

The kusurwar R a cikin bututun murabba'in shine madaidaicin baka a mahaɗin jiragen sama guda biyu, wanda gabaɗaya shine rabin diamita na layin tsakiya na kusurwar baka R.Darajar baka mai lankwasa R shine gabaɗaya 1.5 ~ 2.0 sau diamita bututu.An ƙayyade girman kusurwar R bisa ga kauri na bangon bututun murabba'in.An raba kusurwar R zuwa kusurwar R na ciki da kusurwar R na waje.R na ciki shine gabaɗaya 1.5 ~ 2 sau kauri bango.Hakanan ana iya samar da bututun ƙarfe na murabba'i tare da kusurwoyin R daban-daban bisa ga buƙatun mai amfani.
Misali, ga bututun karfe rectangular tare da baka madauwari R, A=1.0MM, diagonal=1.15MM, ta yaya aka san kusurwar R?Idan bututun karfe ne mai murabba'i tare da baka, shin hanyar lissafin iri ɗaya ce?Madaidaicin kusurwa yana da tsayin A da faɗin B, diagonal na C, kuma radius na baka na kusurwa huɗu R daidai yake.Yi lissafin girman R ta wannan tsari: (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 .
Ya kamata a jaddada a nan cewa kusurwar R na ƙananan bututun rectangular baya nufin baka, amma kusurwar tsakiya.Arc yana nufin wani yanki akan kewaye, kuma kusurwar da aka haɗa ta layin tsakanin iyakar biyu na arc da cibiyar ita ce kusurwar tsakiya.Tunda kewayen da'irar shine 2 π R kuma madaidaicin kusurwar tsakiya shine 2 π, tsayin baka wanda yayi daidai da kusurwar tsakiya shine 2 π R/2 π=R.Saboda haka, ana samun tsayin baka wanda yayi daidai da kowane kusurwar tsakiya a (radiyon radiyo)=aR.Hanyoyin aunawa da kayan aikin don kusurwar bututu R sun haɗa da ma'aunin R da majigi.Za a iya amfani da ma'aunin R don maki mai kauri, na'urar jijiya don maki masu kyau, da kuma CMM don manyan buƙatu.
