Answer
Amasoko y'umuhengeri araguka kandi akagabanuka muburyo bwose. Niba bore yubuso bukabije $ R_a $ ni hejuru (urugero, $> 125 μin $), diameter yo hanze yisoko izahura no kwambara nabi. Uku kunanura urukuta rwa radiyo $ b $ bigabanya igipimo cyimpeshyi ukurikije $ K ∝ b $. Byongeye kandi, ubushyamirane bwongera ubushyuhe bwimikorere, bushobora kwihutisha kuruhuka mubikoresho nka SAE 1070. Kubisabwa byizunguruka cyane (urugero, $> 10 ^ 6 $ cycle), bore igomba kubahwa kugeza kurangiza $ 32 μin $ cyangwa byiza. Muri pompe yamavuta yo mu kirere, aho hakoreshwa amadolari 17-7PH $, bore ikunze gukoreshwa cyane cyangwa igashyirwaho amavuta yumye ya firime yumye kugirango igabanye ubwo bushyamirane kandi ikumire kubyara imyanda yimyanda ishobora kwangiza sisitemu.
