Answer
Kunanirwa guterana kwimpeta birashobora kubaho haba mugukata impeta cyangwa ibikoresho bya groove bitanga. Gukata impeta ni kunanirwa gukanika impeta ubwayo, ubarwa nka $ P_s = \ frac {D T π σ_s} {S} $, aho $ \ sigma_s $ ni imbaraga zo gukata. Nyamara, mubikorwa byinshi byubuhanga ukoresheje aluminium cyangwa ibyuma byoroshye, 'Groove Deformation' ibanza. Nigihe umutwaro wa axial utera urukuta rwa groove gutanga kandi 'isahani' cyangwa gusohoka. Mugihe urukuta ruhindutse, impeta itangira guhindagurika (isahani). Ibi bihindura imizigo kuva kogosha ikomatanya kugunama no guhagarika umutima, bishobora gutuma impeta 'isohoka' muri ruhago ku gice cyimbaraga zayo. Ba injeniyeri bagomba gukoresha ikintu cyumutekano byibuze 2: 1 kubara umusaruro wa groove.
