Andmụba na nyocha nke mmekọrịta dị n'etiti ngagharị na ọkwa na ọnọdụ nke mkpanaka na-ejikọ na eriri anọ na-ejikọ, anyị nwere ike ịtụle ihe nlere dị iche iche iji chọpụta ihe dị iche iche.

Enwere ike ekekọrịta mmekọrịta nha nha ikpe atọ. Na nke mbụ, mgbe "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.

Iji guzobe ọnọdụ a overlap, ndị na-esote ya ga-ejide: "D + C> B + A". Nke a pụtara na "D> C + A", nke kwekọrọ n'ọnọdụ enyere. Ọzọkwa, enwere ike ịkọwa na enwere ike ị overliop na colniness nke dị n'akụkụ Rod (c), na-eji echiche yiri ya. N'ihi ya, pog cog (b ma ọ bụ c) nke ogige kacha mkpụmkpụ (a) na-agbanye na mkpanaka dị n'akụkụ abụọ ahụ na-erughị 180 Celsius. Nke a pụtara na akụkụ nke swing bụ oke na-erughị 180 Celsius, ma karịa karịa 50 Celsius (dị ka ọnọdụ).

N'okwu nke abụọ, mgbe a na b bụ mkpanaka na-adị iche, otu usoro a ga - esi tinye okwu ikpe kachasị gosipụta na ebe dị mkpụmkpụ (a) ka nwere ike ịgbagharị na ogwe abụọ n'akụkụ abụọ ahụ. Ya mere, anyị nwere ike ịhapụ ntụle nke ọnọdụ a.

Na nke atọ, anyị tụlere ngagharị ahụ n'etiti ụlọ mmanya kachasị ogologo (d) na ogwe abụọ ahụ n'akụkụ abụọ. Site na ọnọdụ ama ama, anyị nwere ike ịzinyere nke ahụ "D> B + AC" na "D> E + AV". Nke a pụtara na mkpanaka D enweghị ike ịgbatị na colniness na mkpanaka abụọ dị nso. Ọzọkwa, ọ bụrụ na a ga-amanye Doodlay na Coldlọ ndị agbata obi, anyị ga-enwe "d + C> B + A" na-emegide ọnọdụ enyere).

Ijikọ nkwubi okwu ahụ site na nke mbụ, nke abụọ na nke atọ, anyị nwere ike ịchịkọta nke ahụ, n'okpuru ọnọdụ nke "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°.
