Answer
Groove deformation ibaho mugihe umutwaro $ P $ urenze imbaraga zo kugabanya umusaruro wibikoresho bya groove, mubisanzwe bigaragara mumazu ya aluminium cyangwa ibyuma byoroshye. Gusuzuma bikubiyemo kugenzura igikoni nyuma yo gusenywa; 'kuzunguruka' cyangwa inkongi y'umuriro yerekana ko impeta yegamiye munsi yumutwaro, bigatuma plastike yimbere. Kugira ngo wirinde ibi, abashakashatsi barashobora kongera ubujyakuzimu bwa $ d $, bagakoresha icyuma gikomeye hagati yimpeta nigice cyapakiwe kugirango bagabanye igitutu, cyangwa bagaragaza impeta ifite urukuta runini rwa radiyo kugirango bongere aho bahurira. Iharurwa ryumutwaro ntarengwa ushingiye ku musaruro wa groove ni $ P_ {max} = (D \ cdot d \ cdot \ pi \ cdot \ sigma_ {umusaruro}) / K $, aho $ K $ ari ikintu cyumutekano (mubisanzwe $ 2.0 $ kuri static na $ 4.0 $ kumitwaro ifite imbaraga).
