Kedu otu esi akọwa akụkụ R nke square tube kpọmkwem na ọkọlọtọ mba?

Nkuku R dị na tube square bụ ntụgharị mgbanwe na njikọ nke ụgbọ elu abụọ, nke na-abụkarị ọkara dayameta nke etiti etiti nke akụkụ arc R.The uru nke curved arc R bụ n'ozuzu 1.5 ~ 2.0 ugboro ọkpọkọ dayameta.A na-ekpebi oke nke akụkụ R dị ka mgbidi mgbidi nke tube square.A na-ekewa akụkụ R ka ọ bụrụ akụkụ R dị n'ime yana akụkụ R nke mpụta.The esịtidem R bụ n'ozuzu 1.5 ~ 2 ugboro mgbidi ọkpụrụkpụ.Enwere ike ịmepụta tubes ígwè square nwere akụkụ R dị iche iche dịka ihe onye ọrụ chọrọ.
Dịka ọmụmaatụ, maka ọkpọkọ ígwè akụkụ anọ nwere arc okirikiri R, A=1.0MM, diagonal=1.15MM, kedu ka ị ga-esi mara akụkụ R?Ọ bụrụ na ọ bụ ọkpọkọ nchara square nwere arc, usoro mgbako ọ bụ otu?Otu akụkụ anọ nwere ogologo A na obosara nke B, diagonal nke C, na radius nke arcs nkuku anọ R hà nhata.Jiri usoro a gbakọọ nha R: (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 .
Ekwesịrị imesi ya ike ebe a na akụkụ R nke obere akụkụ akụkụ anọ adịghị ezo aka na arc, kama akụkụ etiti.Arc ahụ na-ezo aka na akụkụ dị na gburugburu, na akụkụ agụnyere nke ahịrị n'etiti nsọtụ abụọ nke arc na etiti bụ etiti etiti.Ebe okirikiri okirikiri bụ 2 π R na akụkụ etiti ya kwekọrọ bụ 2 π, ogologo arc dabara na akụkụ etiti otu bụ 2 π R/2 π=R.Ya mere, a na-enweta ogologo arc nke dabara na akụkụ etiti ọ bụla a (radian unit) = aR.Ụzọ nha na ngwaọrụ maka square tube R angle gụnyere R nlele na projector.Enwere ike iji nlele R maka isi ihe siri ike, ihe nrụpụta maka isi ihe dị mma, yana CMM maka nnukwu ihe achọrọ.
