Gukoresha mandel yo kwaguka ikabije kwagura impeta izenguruka imipaka yayo ya elastike bizavamo ihinduka rihoraho, rizwi nka 'gushiraho.' Impeta ntizasubira kumurambararo wambere, biganisha ku gutakaza 'kwizirika' kuri ruhago. Imibare, kwaguka ntarengwa $ E_ {max} $ mbere yo gutanga umusaruro bigengwa na formula $ \ sigma = \ frac {E \ cdot t \ cdot \ Delta D} {D_m ^ 2} <S_y $. Niba impeta idafashe hepfo ya groove, irashobora kunyeganyega cyangwa kuzunguruka mugihe cyo gukora, biganisha ku kwambara (fretting) no gutsindwa amaherezo. Kugira ngo ibi bigabanuke, mandrels igomba gutegurwa hamwe no guhagarara gukomeye cyangwa ubunini buringaniye bwa diameter ya shaft hiyongereyeho byibuze bisabwa kugirango ushyire.
