Answer
Impeta y'imbere irahagarikwa kugirango ushyire muri bore, mugihe impeta zo hanze zaguwe kugirango zishyirwe hejuru yumutwe. Itandukaniro ritegeka igikoresho geometrie. Ku mpeta y'imbere, igikoresho kigomba kugira uburyo bwo 'kwikuramo' (nka feri ya conique) igabanya diameter. Ku mpeta zo hanze, igikoresho 'gikwirakwiza' cyangwa mandel ikoreshwa kugirango yongere diameter. Igishushanyo cyibi bikoresho kigomba kwemeza ko 'Ntarengwa Ntarengwa' $ f_ {max} = D_ {ubuntu} - D_ {yashyizwemo} $ ntirenza imipaka y’ibikoresho. Ikigeretse kuri ibyo, igikoresho cyo guhuza igikoresho kigomba kuba cyoroshye kugirango wirinde gukata impande zimpeta, nizo ngingo zoroshye cyane zo gutangiza. Ku mpeta nyinshi, igikoresho kigomba kandi kubuza guhinduka 'kuzenguruka' cyangwa guhuzagurika mugihe cyo kwaguka / kugabanuka.
