Juyawa ita ce ƙarfin juyawa wanda ke sa abu ya juya. Idan ka buɗe ƙofa ko ka murɗa sukurori, ƙarfin da kake amfani da shi ya ninka ta nisan da ke tsakanin wurin juyawa da juyawa yana haifar da juyawa.
Ga hinges, karfin juyi yana wakiltar karfin juyawa da murfi ko ƙofa ke samarwa saboda nauyi. A taƙaice: Girman murfin da kuma nisan tsakiyar nauyi daga hinges ɗin, karfin juyi yana ƙaruwa.
Fahimtar ƙarfin juyi yana taimaka maka ka zaɓi madaidaicin hinge don kada allon ya yi lanƙwasa, ya faɗi kwatsam, ko kuma ya ji haske sosai yayin rufewa.
Me Yasa Muke Bukatar Lissafin Ƙarfin Hinge?
Ana amfani da hinges sosai a cikin murfin da aka juya da kuma tsarin kabad. Misalan sun haɗa da:
● Allon kwamfutar tafi-da-gidanka - Dole ne hinged ɗin ya samar da isasshen ƙarfin juyi don daidaita nauyin allon.
● Murfin kayan aiki ko na kabad - Waɗannan galibi suna da faɗi da nauyi, suna haifar da ƙarfin juyi mai girma.
● Ƙofofin kayan aikin masana'antu ko murfi na kayan aiki - Faifanan masu nauyi suna buƙatar maƙallan ƙarfe masu ƙarfi don hana faɗuwa da ba a so.
Idan ƙarfin juyi ya yi ƙasa sosai, murfin zai rufe.
Idan ƙarfin juyi ya yi yawa, murfin zai yi wuya a buɗe ko kuma ya ji tauri.
Lissafin karfin juyi na hinge yana tabbatar da cewa karfin juyi na hinge ya fi karfin juyi da murfi ya samar, wanda hakan ke haifar da kwarewa mai santsi da aminci ga mai amfani.
Yadda Ake Kimanta Juyin Juya Halin Karkace-karkace
Babban ƙa'idar ita ce: Karfin juyi = Ƙarfi × Nisa.
Tsarin shine:
T = F × d
Ina:
T= karfin juyi (N·m)
F= ƙarfi (yawanci nauyin murfin), a cikin Newtons
d= nisan daga maƙallin zuwa tsakiyar murfi na nauyi (nisan kwance)
Don ƙididdige ƙarfi:
F = W × 9.8
(W = nauyi a cikin kg; 9.8 N/kg = hanzarin nauyi)
Ga murfi mai rarrabawa iri ɗaya, tsakiyar nauyi yana nan a tsakiyar wurin (L/2 daga maƙallin).
Misali Lissafi
Tsawon murfi L = 0.50 m
Nauyi W = 3 kg
Nisa tsakanin tsakuwa d = L/2 = 0.25 m
Mataki na 1:
F = 3 kg × 9.8 N/kg = 29.4 N
Mataki na 2:
T = 29.4 N × 0.25 m = 7.35 N·m
Wannan yana nufin tsarin hinges dole ne ya samar da kimanin 7.35 N·m na karfin juyi don magance nauyin murfin.
Idan ana amfani da hinges guda biyu, kowanne hinges yana ɗauke da kusan rabin ƙarfin juyi.
Kammalawa
Don kimanta ƙarfin juyi da ake buƙata:
● Karfin juyi (T) = Ƙarfi (F) × Nisa (d)
● Ƙarfi yana fitowa ne daga nauyin murfin
● Ana ƙayyade nisa ta hanyar tsakiyar nauyi
● Hinji biyu suna raba nauyin ƙarfin juyi
● Koyaushe zaɓi hinge mai ƙarfin juyi kaɗan fiye da ƙimar da aka ƙididdige
Waɗannan ƙa'idodi ne kawai na asali. A aikace-aikace na gaske, dole ne a yi la'akari da ƙarin abubuwa yayin ƙididdige ƙarfin juyi. Jin daɗin tuntuɓar mu, kuma za mu iya sake duba aikin ku dalla-dalla tare!
