Gịnị a na-akpọ oge nke ike? Esi kọwaa ya?

Ka anyị gbalịa ịghọta ihe a na-akpọ a ike mgbe. Nke a na okwu a na-eji na physics. Nyochaa n'okpuru okwu na-egosi a na-arụ ọrụ nke ubu na mmasị ya ike.

atụmatụ

Inyocha ajụjụ nke ihe a na-akpọ oge nke ike dị mkpa iji na-ekwu banyere na nkeji nke a bara uru. Na SI usoro ọ na-tụrụ na nm.

torque

Torque nke a ike banyere a na-ekwu bụ na ọ bara uru metụtara na leverage na ike. Na kwa ụbọchị, ndị mmadụ na-eji "menjuobi iwu", nke dabeere kpọmkwem na ike na-ekwu.

Dị ka ihe atụ, iji mee ihe ọtụtụ-Ngabiga, anyị mkpa ịmata ihe a na-akpọ oge nke ndị agha, na otú kwesịrị ekwesị itinye. Jirinụ akpọ n'agbata ngwa mgbe na pivot ebe.

Dị ka ihe atụ, ike na-emeghe ụzọ, pushing ya si arịọnụ ihe. Iji ghọta ihe mere na nke a bụ otú ike na-eme, i kwesịrị ịmata ihe a na-akpọ oge nke a ike banyere ihe axis.

Ka e were ya na ị chọrọ na-emeghe ụzọ, na-enwe a obosara mita, annexing 100 N. Ime ọ ga-abụ na atọ na ebe:

• nso adabere;
• na center;
• na nsọtụ nke kwaaji.

N'ihi na nke mbụ ahụ ubu bụ efu, mmọdo, ọrụ na ogwe aka ga-dọgburu ike uru nke efu.

Maka nhọrọ ke center nke ụzọ, na oge ga-ederịta akwụkwọ ozi 50 nm. Na-ala nke-uzọ akwukwo ebe ga nwere a kacha uru nke 100 nm.

Dị otú ahụ mgbawa eme ka o kwe ya ikwubi na ọnwụ na anya na-ahụ ụgwọ atụrụ site a uru na mgbalị.

nri ubu

N'ihe banyere nke itinye a ike na ihe n'akuku, ọ gaghị ekwe omume na-ekwu okwu banyere ịchọpụta agha ubu dị ka e weere ya na mbụ. Ịnagide nke a ọrụ, ị ga-eji nri ubu. Jirinụ agha a na-akpọ perpendicular ogologo na omitted si pivot uche na akara nke ihe nke ike.

Iji chọpụta na ogwe aka dị ike, ịgbatị akara. Mgbe ahụ, ọ na-lowered perpendicular si pivot ebe.

N'ihi bụ a triangle na nri angles. Iji iwu nke ihe ọmụmụ trigonometry, o kwere omume site na imi na-ekpebi oge nke ike.

Iche na ike na-etinyere na na n'akuku nke 45 degrees. Na nke a, na oge nwetara 70 nm. Ọ na-aghọ doro anya na-arụ ọrụ iji na-emeghe ụzọ na n'akuku nke 0 degrees. Ike dị otú ahụ ọ dịghị projections nwere ike ime ka a rotational ije. Enweghị ya n'ubu, ndị ọzọ karịa efu, adịghị ekwe ka ike ike torque. N'ịtụgharị uche n'ihe a na-akpọ oge nke ike, ọ ga-kwuru na ọ bụ a vector ibu. Iji chọpụta ntụziaka nke oge nke ike, jiri aka nri na-achị. N'otu aka ahụ, chọpụta ntụziaka nke vector angular ike ọsọ.

Gịnị bụ pụrụ iche banyere nke a na-achị? Kpuchie n'ọbụ aka aka nri axis nke adiana, nke mere na ntụziaka nke mkpịsị aka kwekọọ ntụziaka nke etinyere ike. Na mkpịsị aka ukwu-ekpebi ụzọ nke angular ọkụ vector nke ike. Gịnị a na-akpọ oge nke a ike banyere a ofu mgbe? Nke a bara uru, nke na-ejikọ ndị ntule nke vector ike oge na axis banyere nke ngụkọta oge ga-rụrụ.

The isi nke ike bụ vector nke bụ nchikota nke niile oge nke onye agha na-eme ihe na usoro na-akwanyere ndị otu ihe ahụ. Ya oku center iji mee ka ụwa dum nke na agha.

Na izugbe n'onwe, n'ihi ihe na bụla siri ike usoro bụ otu ihe ahụ dị ka ihe nke torque nke isi usoro dị ka nke ọma dị ka vector nke agha etinyere etiti nke ịnya ụgbọ ala.

ọgwụgwụ

N'ihi na a nkọwa nke torque etinyere isi n'iwu nke Ọnọdụ, nke e ji mara ndị rotational ngagharị. Ọ na-akọ na oge nke inertia, angular osooso, torque. Mgbe Archimedes guzobere aka nri, na-enweghị ihe ọ bụla mgbanwe ya e ji mee ihe fọrọ nke nta afọ 1,900. Naanị na nkera nke abụọ nke narị afọ nke 17 French ọkà mmụta sayensị P. Pierre Varignon ya gbanwere na n'ihi torque agha.

Ọ bụrụ na ndị menjuobi bụ na ịha, na ịha nhata nke M1 = M2. Torque bụ njirimara onye rotational ike nke edinam. Ọ na-adabere ọ bụghị naanị na ike ma ya n'ubu. Iji ihighari aku, na-eji a ogologo spana. Kposara ngwa ngwa ua sikruuokwomoto enwe a zuru ezu ogologo ahụ.
