Lokho okubizwa ngokuthi okwamanje force? Indlela bakuchaza?

Ake sizame ukuthola ukuthi ibizwa ngokuthi amandla iphuzu. Leli gama livame ukusetshenziswa physics. Ihlaziye ngaphansi eside lisikisela umsebenzi ehlombe enamathiselwe ibutho lakhe.

Izici

Ukuhlaziya umbuzo nalokho okubizwa ngokuthi okwamanje force kuyadingeka ukuze basho futhi amayunithi kwaleli nani. Kuhlelo SI ke ulinganiswa Nm.

torque engu

Torque webutho mayelana iphuzu ukubaluleka elihlobene ne asizakale namandla. Ekuphileni kwansuku zonke, abantu bavame ukusebenzisa 'isigwedlo umthetho ", ogxile ngokunembile kuphoyinti amandla.

Ngokwesibonelo, ukuze babuyele-swing, sidinga ukwazi ukuthi ubizwa ngokuthi okwamanje force, futhi kanjani ukuze unamathisele kahle. Ihlombe ngokuthi nesikhathi esithileko hlangana iphuzu isicelo kanye iphuzu zungeza.

Ngokwesibonelo, kunzima ukuvula umnyango, kuyisunduzele kusukela amaphuzu obandayo. Ukuze uqonde ukuthi kungani lokhu kunzima kangaka ukwenza, udinga ukwazi ukuthi ubizwa ngokuthi okwamanje webutho mayelana axis.

Ake sithi kudingeka avule umnyango, kokuba imitha ububanzi, annexing 100 N. Ukusebenzisa kumele kube ezindaweni ezintathu:

• eduze kokuhlanganisayo;
• maphakathi;
• emaphethelweni ngendwangu.

Ngoba kuqala icala ehlombe zero, ngenxa yalokho, umsebenzi on the ingalo uzobe wayenethonya amandla ukubaluleka zero.

Ukuze ukhetho maphakathi umnyango, okwamanje kumelwe ilingane 50 Nm. Ukuze phansi emnyango leaf iphuzu uzoba seqiwe 100 Nm.

izibalo ezinjengalezi enze kube nokwenzeka ukuba siphethe ngokuthi ukulahleka e ibanga incephezeliswa nzuzo e umzamo.

ehlombe langakwesokudla

Endabeni kokusebenzisa amandla engela, akunakwenzeka ukuba akhulume ngokuhlangenwe sokunquma amabutho zasemahlombe njengesikhumbuzo lalibhekwa ngaphambili. Ukuze sibhekane nale umsebenzi, kufanele usebenzise ehlombe langakwesokudla. Ehlombe amabutho okuthiwa obuphelele perpendicular ukuthi angekho iphuzu zungeza ku ulayini isinyathelo bebutho.

Ukuze sithole amandla ingalo, ukunweba line. Khona-ke lehliselwa perpendicular kusukela iphuzu zungeza.

Umphumela calantsatfu engeli kwesokudla. Ukusebenzisa imithetho trigonometry, kungenzeka ngokusebenzisa itheku ukucacisa okwamanje force.

Ngokuthi amandla sisetshenziswa i-engela 45 degrees. Kulokhu, isikhathi etholwe 70 Nm. Kuba sobala ukuthi kungasebenzi ukuvula umnyango i-engela 0 degrees. Lawo mandla angenye ayinakho projection ukuthi singabangela ukunyakaza ukujikeleza. Ukungabikho ehlombe, ngaphandle zero, ayivumeli amandla akhe ukuze adale torque engu. Ecabanga ngalokho okwenziwa ibizwa ngokuthi okwamanje force, kufanele kuphawulwe ukuthi ubuningi vector. Ukuze sithole isiqondiso okwamanje force, sebenzisa umthetho sangakwesokudla. Ngokufanayo, ukunquma isiqondiso Vector Isivinini emincane.

Yini ekhethekile ngale lo mthetho? Cover entendeni ngakwesokudla-eksisi ujikeleza, ukuze isiqondiso iminwe ahambisana isiqondiso amandla osetshenziswayo. On the isithupha ukunquma isiqondiso emincane umfutho Vector force. Lokho okubizwa ngokuthi okwamanje webutho mayelana iphuzu esinqunyiwe? Lokhu value, okuyinto uxhuma projection of the mzuzu Vector amandla futhi eksisi mayelana nokuthi iziphi izinhlelo ukubala oyokwenziwa.

Iphuzu eliyinhloko ngezikhwepha uyindoda vector okuyinto isamba sazo zonke izikhathi zamabutho ngabanye ukuthi ukwenza ohlelweni mayelana iphuzu elifanayo. call centre wakhe ukuletha lonke uhlelo amabutho.

Ngo samuntu jikelele, umphumela isenzo kunoma iyiphi uhlelo okuqinile kuyafana isenzo torque kohlelo main kanye vector amabutho isetshenziswa maphakathi ukushayela.

isiphetho

Ukuze uthole incazelo eningiliziwe torque isicelo emthethweni oyisisekelo ebudlelwaneni, okuyinto ephawula ukunyakaza ukujikeleza. Uyalandisa lo mzuzu inertia, ukushesha emincane, torque. Ngemva Archimedes esungulwe sangakwesokudla, ngaphandle kugucuka iye yasetshenziswa cishe 1900 iminyaka. Kuphela engxenyeni usosayensi ongumFulentshi wekhulu le-17 P. Pierre Varignon yesibili ke lashintsha futhi ngenxa amabutho torque engu.

Uma isigwedlo kuyinto zilingana, le nokulingana M1 = M2. Torque kuwuphawu ibutho ukujikeleza yesenzo. It akuxhomekile nje kuphela esimweni amandla kodwa ehlombe. Ukuze uyasikrufulula nut, sebenzisa ukusonta eside. Izikulufu ngokushesha baphotha ukufakwa kokumqoka kuphela kokuba isibambo ngokwanele eside.
