Answer
Gutanga urukuta rwa Groove bibaho mugihe umutwaro wa axial umutwaro $ P $ urenze imbaraga zo kugabanya umusaruro wibikoresho byamazu. Ibi birasanzwe mugihe ukoresheje ibyuma bigumana impeta mumazu ya aluminium cyangwa plastike. Guhangayikishwa kwiherereye aho uhurira ni $ \ sigma_c = \ frac {P} {A_ {guhuza}} $. Niba $ \ sigma_c> \ sigma_ {y, amazu} $, ibikoresho bihinduka muburyo bwa plastike, bigakora umwirondoro umeze nkigitambambuga muri groove. Iyo groove imaze guhindurwa, impeta itakaza inkunga ya perpendicular kandi amaherezo 'izasohoka'. Mu gusesengura kunanirwa, ibi bigaragazwa no kuba hariho 'kuzunguruka-hejuru' inkombe. Kugira ngo iki kibazo gikosorwe, abashakashatsi bagomba kongera ubujyakuzimu bwa $ d $, bagakoresha ibikoresho bikomeye byo guturamo, cyangwa bagakoresha 'Groove Guard' cyangwa impeta nini kugirango bagabanye umutwaro ahantu hanini.
