thawb ntawm qhov deb dua ntawm tus pin txhais tau tias koj siv lub zog loj dua. Xav txog tias tus kws kho tsheb thawb qhov kawg ntawm 0.3-meter-ntev torque wrench siv 9 Newton-meters ntawm lub zog. Xam lub zog tangential. F_t=τ/R=9 Newton-meters/0.3 meters=30 Newtons.
Lub zog tangential yog dab tsi?
: a lub zog uas ua rau lub cev txav mus los ntawm kev coj mus rau txoj kev nkhaus ntawm lub cev.
Koj pom tangential li cas?
Faib qhov ncig los ntawm lub sijhawm nws siv sijhawm los ua kom tiav ib qho kev sib hloovtxhawm rau nrhiav qhov nrawm nrawm. Piv txwv li, yog tias nws siv sijhawm 12 vib nas this los ua kom tiav ib qho kev sib hloov, faib 18.84 los ntawm 12 kom pom qhov tangential tshaj tawm sib npaug 1.57 ko taw ib ob.
Yuav ua li cas koj pom tangential quab yuam nyob rau hauv voj voog?
Tangential acceleration yog qhov thib ob derivative ntawm angular displacement, α. Lub arc ntawm ib feem ntawm lub voj voog yog ib qho kev ncua deb muab los ntawm rθ. Qhov no txhais tau tias tangential acceleration yog rα. Newton txoj cai thib ob rau tangential quab yuam yog ΣFt=mrα.
Puas tangential quab yuam tib yam li torque?
Yog li, nws yog tsuas yog cov tangential ntawm lub zog uas cuam tshuam rau lub zog torque (vim nws yog perpendicular rau kab ntawm qhov taw tes ntawm qhov kev txiav txim ntawm lub zog thiab lub ntsiab lus pivot). … Tom qab ntawd, txhua lub zog yuav ua rau lub zog loj. Net torque yog qhov sib npaug ntawm tus kheej torques.

Formula rau magnetomotive quab yuam?
Magnetomotive force (mmf), F m =NI ampere-turns (At), qhov twg N=tus naj npawb ntawm conductors (los yog tig) thiab kuv=tam sim no hauv amperes. Txij li thaum 'tig' tsis muaj units, SI unit ntawm mmf yog ampere, tab sis kom tsis txhob muaj kev tsis sib haum xeeb 'ampere-turns', (A t) yog siv nyob rau hauv tshooj no.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Puas centrifugal quab yuam ua rau tidal bulge?
Nkauj tawm tshiab nyob deb ntawm lub ntiaj teb tsis yog los ntawm lub zog centrifugal. Nws yog tshwm sim los ntawm qhov tseeb tib yam qhov ze-sab bulge yog tshwm sim los ntawm: lub hli lub ntiajteb txawj nqus. Tsis tas li ntawd, cov teebmeem tidal tsis yog tshwm sim los ntawm tag nrho lub zog ntawm lub ntiajteb txawj nqus zoo li lub ntiaj teb orbits.
Nyob rau hauv quab yuam kom suav nrog?
Kev txhais lub zog kom suav nrog: tus neeg muaj zog thiab tsis tuaj yeem tsis quav ntsej Thaum nws yeej nws thawj peb qhov kev sib tw, lwm tus players pom tau tias nws yog lub zog rau yuav suav nrog. Puas yog quab yuam suav nrog lossis quab yuam tsis suav nrog?
Vim li cas iris nyob rau hauv tseem quab yuam?
Nyob rau hauv ntu no, txawm li cas los xij, cov kiv cua tau kawm vim li cas Iris tsis tuaj. … Nws tau txais kev phem heev uas Deon, Tseem Ceeb, swooped los tiv thaiv Iris los ntawm kev siv nws lub peev xwm los tswj nws kom tsis txhob hla dhau ntau lub dav hlau ntawm sab cev nqaij daim tawv, txav nws mus rau "
