Answer
Ubushobozi bwo gusunika impeta igumya kugarukira kubintu bibiri: imbaraga zogukata impeta no guhindura imikorere ya groove. Amashanyarazi atagabanije $ P_r $ abarwa nka $ P_r = \ frac {D T \ pi au_s} {K_s} $, aho $ D $ ni diameter ya shaft / bore, $ T $ nubunini bwimpeta, $ au_s $ nimbaraga zogosha ibikoresho (mubisanzwe bifatwa nk $ 0.6 \ inshuro \ sigma_ {umutekano muke} $), Nyamara, mubihe byinshi, ibikoresho bya groove (akenshi aluminium cyangwa ibyuma byoroshye) bitanga mbere yimpeta. Amashanyarazi agarukira kuri $ P_g $ ni $ P_g = \ frac {D d \ pi au_y} {K_s} $, aho $ d $ ni ubujyakuzimu bwa $ na $ au_y $ nimbaraga zo gutanga umusaruro wibikoresho. Abashushanya bagomba gufata munsi yizo ndangagaciro zombi nkubushobozi bwinteko itekanye.
