Answer
Ihindagurika rya Groove riba mugihe impagarara zo kwikuramo ziterwa nimpeta igumana zirenze imbaraga zumusaruro wibikoresho bya groove (akenshi aluminium cyangwa ibyuma byoroshye). Ubushobozi ntarengwa bwo gushingira ku musaruro wa groove ni $ P_g = \ frac {D \ cdot d \ cdot \ pi \ cdot \ sigma_y} {K} $, aho $ D $ ari diameter, $ d $ ni ubujyakuzimu, $ \ sigma_y $ ni imbaraga zumusaruro wibikoresho, kandi $ K $ ni ibintu byumutekano (mubisanzwe 2). Niba $ P_ {yashyizwe mu bikorwa}> P_g $, urukuta rwa groove ruzahinduka plastike, rukore umwirondoro 'wuzuye'. Uku gutembera gutuma impeta igumana isahani (ihengamye), itangiza ibice bya radiyo yingufu zishobora amaherezo gusohora impeta muri ruhago. Kugira ngo wirinde ibi, abajenjeri bagomba kwerekana ibinure bikomye cyangwa kongera ubujyakuzimu, mugihe uburinganire bwimiterere yabyo bugumye mumipaka.
