Ni irihe sano riri hagati yubugari bwurukuta rwa radiyo hamwe na groove ituje mu mpeta zizunguruka?

Urukuta rwa radiyo $ b $ yimpeta rugena kurwanya kuroba nubushobozi bwayo bwo kuguma rwicaye muri ruhago. Urukuta runini rwa radiyo yongerera umwanya wa inertia $ I = \ frac {t b ^ 3} {12} $, ifasha kurinda impeta guhindukira ikava mu gikoni munsi y’umuvuduko mwinshi. Nyamara, urukuta rugari cyane rutuma kwishyiriraho bigorana nkuko guhangayikishwa mugihe cyo kwishyiriraho $ S_ {inst} = \ frac {E t (D_g - D_i)} {(D_g - t) D_i} $ irashobora kurenga imipaka igoye, igatera ihinduka rihoraho. Ikigereranyo cyiza ni $ b \ hafi 10t $ kubikorwa bisanzwe.
