Ho Hloekisa tlhahlobong ea kamano pakeng tsa ho sisinyeha le boholo ba ho sisinyeha le boholo ba lithupa tse hokahanyang ho etsa hore ho be le pono e nepahetseng. Ka ho nahanisisa ka boholo ba molamu o mong le o mong, re ka tseba tharollo ea mefuta e fapaneng ea mantlha ea mekhoa e mengata ea mantlha ea mekhoa e nkileng moralo.

Kamano e lekanang e ka aroloa maemong a mararo. Boemong ba pele, ha "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.

Ho theha boemo bona bo fetang tekano, ho se lekane ka mor'a ho latelang ho lokela ho re: "D + B +. Sena se bolela hore "D> c + a", e lumellanang le maemo a fanoeng. Ntle le moo, e ka netefatsoa hore a ka koatoa hape a koetlisetse ka molamu o fapaneng (C), o sebelisa mabaka a tšoanang. Kahoo, phule e fapaneng (B kapa c) ea bareki e khutšoanyane haholo (a) e ka hlakole lipalo tse peli tse haufi le palo e ka tlase ho 180 °. Hona ho bolela hore lehlakore la swing le lekantsoe ho feta 180 °, empa le leholo ho feta 50 ° (joalo ka boemo).

Moetlo oa bobeli, ha A le B ke lipalo tse ka lehlakoreng le leng, mokhoa o tšoanang le oa pele o ka sebelisoa ho bontša hore bara bo bokhutšoanyane bo ka potoloha le mekoallo e 'meli e haufi. Ka hona, re ka siea puisano ea boemo bona.

Tabeng ea boraro, re nka mokhoa o lekanang pakeng tsa bareng e telele ka ho fetisisa (d) le mekoallo e 'meli e haufi. Ho tloha maemong a tsebahalang, re ka nahana hore "D> D> E + AB". Sena se bolela hore molamu D ha o khone ho otloloha le ho koata ka lithupa tse peli tse haufi. Ho feta moo, haeba D e ne e ka koaloa le lithunya le lithupa tse haufi, re ne re tla be re "D + C" le "(li hanyetsa maemo a fanoeng). Ka hona, re fihlela qeto ea hore molamu D o sitoa ho fetelletsa le ho ba Colllinear le lithupa tsa boahisani. Boemong bona, li-angles tsa swing li lekantsoe ka tlase ho 180 °.

Ho kopanya liqeto ho tloha la pele, bobeli le sa boraro, re ka akaretsa seo, tlasa boemo ba "AD < 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°.

Ka ho hlakisa ts'ebetso e amanang lipakeng tsa lithupa tse peli tse nang le liketane tsa bar-Bar, re ka tseba bonolo ka ho khetha molamu leha e le ofe oa ho khetha. Mohlala, haeba molamu o mokhuts'oane o mokhuts'oane o sebelisoang e le foreimi, mochine oa libuka o botsoa o fumanoa. Ka lehlakoreng le leng, haeba lehlakore le leng le le leng la molatsoana o mokhuts'oane le sebelisoa e le sebopeho, mochine o habeli o fumanoa. Ho bohlokoa ho hlokomela hore mokoko, ka har'a korollo, ha o khone ho oela sebakeng sa Columear ka mokotla, le angle ea ho akheha e lokela ho ba ka tlase ho 180 °.

Qetellong, ka tlhahlobo ea kamano lipakeng tsa ho sisinyeha, boholo bo amanang le lithupa tse hokahanyang tsa mabanngoeng tse nkileng. Ka ho utloisisa melao-motheo ena, boenjiniere le baqapi ba ka nts'etsapele le ho ntlafatsa mefuta e fapaneng ea mekhoa ea likopo tse khethehileng.
