Answer
Imirasire ya radiyo ni ikinyuranyo hagati yimpeta yimbere (kumpeta yimbere) cyangwa diameter yo hanze (kumpeta yo hanze) no hepfo ya groove. Ku mpeta zo hanze, niba hari ukurenga gukabije, impeta ifite icyumba kinini cyo kwaguka munsi yingufu za centrifugal mbere yuko ihagarikwa. Ibi bigabanya 'lift-off' nziza RPM. Kugirango wongere ubushobozi bwa centrifugal, impeta igomba gushushanywa hamwe na 'intervention fit' hepfo ya groove. Inzira yimbaraga zisabwa kwagura impeta ni $ F = (4 \ cdot \ pi \ cdot E \ cdot I \ cdot Δr) / R ^ 3 $. Kwemeza $ Δr $ ni bibi (intervention), igice kinini cyingufu za centrifugal gikoreshwa gusa kugirango uzane impeta muri leta idafite aho ibogamiye, bityo byongere umuvuduko muke wo gukora.
