Umubare wumuraba $ N $ uringaniza muburyo bwo gutandukana kandi ugereranije na cube yubushobozi bwimizigo. By'umwihariko, umutwaro $ P $ uhwanye na $ N ^ 4 $. Ariko, kongera $ N $ bigabanya uburebure bwa arc hagati yimpinga, byongera ubukana ariko birashobora gutera ingorane zo gukora no guhangayikishwa cyane nimpinga. Kugirango uhamye, $ N $ igomba kuba integer cyangwa igice-cyuzuye kugirango igabanye imitwaro imwe. Mubisabwa hamwe nizunguruka, umubare udasanzwe wumuraba ukunda guhitamo kwirinda guhuza amajwi hamwe numurongo wizunguruka wa shaft, cyane cyane iyo umuvuduko wibikorwa wegereye inshuro karemano $ f_n = \ frac {1} {2π} \ sqrt {\ frac {k} {m}} $.
