▁component ▁of ▁weight , ▁with ▁the ▁gy ro ▁near ▁its ▁und ef lect ed ▁position . ▁ ▁In ert ial ▁side ▁forces , ▁ar ising ▁from ▁corner ing , ▁cause ▁the ▁vehicle ▁to ▁lean ▁into ▁the ▁corner . ▁A ▁single ▁gy ro ▁introdu ces ▁an ▁asym met ry ▁which ▁will ▁cause ▁the ▁vehicle ▁to ▁lean ▁too ▁far , ▁or ▁not ▁far ▁enough ▁for ▁the ▁net ▁force ▁to ▁remain ▁in ▁the ▁plane ▁of ▁symmetry , ▁so ▁side ▁forces ▁will ▁still ▁be ▁experienced ▁on ▁board . ▁ ▁In ▁order ▁to ▁ensure ▁that ▁the ▁vehicle ▁banks ▁correctly ▁on ▁corners , ▁it ▁is ▁necessary ▁to ▁remove ▁the ▁gy ro scop ic ▁tor que ▁ar ising ▁from ▁the ▁vehicle ▁rate ▁of ▁turn . ▁ ▁A ▁free ▁gy ro ▁keeps ▁its ▁orientation ▁with ▁respect ▁to ▁in ert ial ▁space , ▁and ▁gy ro scop ic ▁moments ▁are ▁generated ▁by ▁rot ating ▁it ▁about ▁an ▁axis ▁per pend icular ▁to ▁the ▁spin ▁axis . ▁But ▁the ▁control ▁system ▁def lect s ▁the ▁gy ro ▁with ▁respect ▁to ▁the ▁ch ass is , ▁and ▁not ▁with ▁respect ▁to ▁the ▁fixed ▁stars . ▁It ▁follows ▁that ▁the ▁pitch ▁and ▁y aw ▁motion ▁of ▁the ▁vehicle ▁with ▁respect ▁to ▁in ert ial ▁space ▁will ▁introduce ▁additional ▁unw anted , ▁gy ro scop ic ▁tor ques . ▁These ▁give ▁rise ▁to ▁uns atisf actory ▁equilib ria , ▁but ▁more ▁seriously , ▁cause ▁a ▁loss ▁of ▁static ▁stability ▁when ▁turning ▁in ▁one ▁direction , ▁and ▁an ▁increase ▁in ▁static ▁stability ▁in ▁the ▁opposite ▁direction .
