Answer
Iyo ibikoresho bya groove bigoye bihagije, uburyo bwo kunanirwa buhinduka mukwogosha impeta ubwayo. Ubushobozi bwo gutwara ibintu bushingiye ku mpeta y'impeta $ P_r $ ibarwa nka $ P_r = \ frac {D \ cdot t \ cdot π τ_ {ult}} {S} $, aho $ t $ nubunini bwimpeta na $ τ_ {ult} $ nimbaraga zogosha zikoreshwa mubintu (mubisanzwe $ τ_ {ult} \ hafi 0.6 \ cdot σ). Ku mpeta izunguruka ikozwe muri SAE 1070 ibyuma bya karubone bifite imbaraga zingana na $ 200 $ ksi, imbaraga zogosha zaba hafi $ 120 $ ksi. Ni ngombwa kumenya ko impeta zizunguruka akenshi ziba nyinshi; icyakora, kubara gukata mubisanzwe byibanda kubyerekeranye nubunini bwumurongo umwe keretse impinduka zihuye neza mugusangira imitwaro. Kuri Smalley-yuburyo bwa 2-impeta, ingirakamaro $ t $ nigiteranyo cyubunini.
