Kukula pa kusanthula pakati pa kuyenda kwa chiyanjano ndi kukula kwake ndi mawonekedwe a ndodo zolumikizirana ndi ma rine a bar a bar anayi-barji, titha kuwunikanso zochitika zosiyanasiyana kuti tiwone zowerengera. Poganizira kukula ndi udindo uliwonse wa ndodo iliyonse, titha kudziwa mayankho a mitundu yosiyanasiyana yamitundu yosiyanasiyana.

Ubale wachibale ukhoza kugawidwa mu milandu itatu. Poyamba, pamene "AD < bc" and a and b are adjacent bars, we can take the shortest bar (a) as the reference member and analyze its relative motion with the two adjacent bars. Since "a < b" and "c < d", we can conclude that rod a can be straightened and collinear with the two adjacent rods. In other words, a can overlap and be aligned with the neighboring rods.

Kuti akhazikitse kuchuluka kwa izi, kusagwirizana kotsatirawa kuyenera kugwira: "d + c> b +. Izi zikutanthauza kuti "d> C + A" A ", yomwe imagwirizana ndi mikhalidwe yopatsidwa. Kuphatikiza apo, zitha kutsimikiziridwa kuti amathanso kuphatikizidwa ndi collinear ndi ndodo yolumikizana (c), pogwiritsa ntchito mfundo zofananira. Chifukwa chake, mtengo wotsutsana (B kapena c) wa bar yochepa kwambiri (a) amatha kungosuntha mitengo iwiri yoyandikana ndi ngodya zosakwana 180 °. Izi zikutanthauza kuti ngodya ya Swing imangokhala ndi zaka zosakwana 180 °, koma wamkulu kuposa 50 (malinga ndi momwe alili).

Mlandu wachiwiri, pomwe a ndi B ndi zotsutsana, njira yomweyo monga mlandu woyamba ungagwiritsire ntchito kuwonetsa kuti bar yochepa kwambiri (a) imatha kuteteza cholumikizira ndi mipiringidzo yawiri yoyandikana nayo. Chifukwa chake, titha kusiya kukambirana za nkhaniyi.

Mu mlandu wachitatu, timaganizira za kuyenda pakati pa khola lalitali kwambiri (d) ndi mipiringidzo iwiri yoyandikana nayo. Kuchokera munthawi zodziwika, titha kudziwa kuti "d> B + ac" ndi "d> e + AB. Izi zikutanthauza kuti ndodo i siyikhala yolimba komanso colinear ndi ndodo ziwiri zoyandikana. Kuphatikiza apo ngati D ikhoza kukhala yodzaza ndi ndodo zoyandikana ndi "d + c> b + ndi" i> b + c "c". Chifukwa chake, timanena kuti ndodo ya ingathetse ndi kukhala colunar ndi ndodo zoyandikana nazo. M'nkhaniyi, mbali zonse ziwiri za Swing ndizochepa mpaka zosakwana 180 °.

Kuphatikiza mfundo zoyambira, chachiwiri, ndi zitatu, titha kufotokoza mwachidule kuti, otsatsa < bc", regardless of the various positions, the shortest bar (a) and the second adjacent bar (b) can rotate relative to each other for a whole circle. However, the opposite pole (b or c) and the two adjacent poles of the shortest bar can only swing relative to each other, with the relative swing angle being less than 180°.

Pofotokoza zoyenda pakati pa ndodo ziwiri zamitundu iyi ya bine, titha kudziwa mtundu wa makina posankha ndodo iliyonse ngati chimango. Mwachitsanzo, ngati ndodo yayifupi kwambiri (ya) yokhala ndi mbali yoyandikana imagwiritsidwa ntchito ngati chimango, makina a crunk-rocn amapezeka. Kumbali inayo, ngati mbali yochepa ya ndodo yachidule imagwiritsidwa ntchito ngati chimango, makina opanga ma rocker awiri amapezeka. Ndikofunikira kudziwa kuti rocker, motsiriza, sangathe kuyimitsa malo opezeka kapena mzere wowonjezera, ndipo ngodya yamphesa iyenera kukhala yochepera 180 °.

Pomaliza, kudzera mu kusanthula ubale pakati pa zofunda zomwe zimachitika, kukula kwa kuyandikira, komanso malo olumikizirana ndi ndodo zolumikizirana mu rinementic kingating'ono, titha kudziwa mtundu wa makina ndi malire ake. Mwa kumvetsetsa mfundo izi, mainjiniya ndi opanga amatha kukhala ndikukulitsa mitundu yosiyanasiyana yamachitidwe a mapulogalamu enaake.
