Lub zog buoyant buoyant force Lub zog nce, lossis lub zog buoyant, uas ua rau ntawm ib qho khoom hauv dej yog sib npaug rau qhov hnyav ntawm cov dej txav los ntawm cov khoom. Txhua yam khoom uas nyob hauv dej muaj qee lub zog buoyant thawb tawm tsam lub ntiajteb txawj nqus, uas txhais tau hais tias txhua yam khoom hauv dej poob qee qhov hnyav. https://www.britannica.com › Discussion-forces-bodies-water
Tshawb nrhiav yog vim li cas ib qho khoom yuav ntab lossis tog - Britannica
uas ib txwm tawm tsam lub ntiajteb txawj nqus, txawm li cas los xij los ntawm gravity. Cov dej siab nce nrog qhov tob vim yog qhov hnyav (gravitational) ntawm cov kua dej saum toj no. Qhov kev nce siab no siv lub zog ntawm cov khoom hauv dej uas nce nrog qhov tob. Qhov tshwm sim yog buoyancy.
Leej twg tsim hydrostatics?
Archimedes tau lees paub nrog qhov kev tshawb pom ntawm Archimedes 'Principle, uas cuam tshuam txog lub zog buoyancy ntawm ib qho khoom uas yog submerged hauv cov kua dej rau qhov hnyav ntawm cov dej txav los ntawm cov khoom. Tus kws ua haujlwm Roman Vitruvius ceeb toom cov neeg nyeem txog cov kav hlau lead tawg nyob rau hauv hydrostatic siab.
RhoGH?
Cov mis uas muab P siab rau ntawm ib qho khoom uas nyob hauv cov kua dej yog: P=rgh. qhov twg. r (rho) yog qhov ntom ntawm cov kua, g yog qhov nrawm ntawm lub ntiajteb txawj nqus.
Dab tsi ua rau lub zog hydrostatic?
Hydrostatic rog yog lub zog tshwm sim los ntawm los ntawm lub siab loading ntawm cov kua ua rau submergednto. Kev suav ntawm lub zog hydrostatic thiab qhov chaw ntawm qhov chaw ntawm lub siab yog cov ntsiab lus tseem ceeb hauv cov tshuab ua kua dej.
Kev tshawb fawb ntawm mechanics thiab hydrostatics yog dab tsi?
Tshuaj kho dej. Fluid mechanics yog kev kawm txog cov teebmeem ntawm lub zog thiab lub zog ntawm cov kua thiab cov pa. Zoo li lwm cov ceg ntawm kev siv tshuab qub, cov ntsiab lus faib ua statics (feem ntau hu ua hydrostatics) thiab dynamics (kua dynamics, hydrodynamics, los yog aerodynamics).

tus neeg raug quab yuam txhais li cas? Tus neeg raug quab yuam yog tus neeg uas coj kev quab yuam-kev ua phem, kev hem, kev hem, lossis kev quab yuam los ntawm ib tus neeg txoj cai kom yuam ib tus neeg xa nyiaj (los yog lwm yam khoom muaj nqis) lossis ua ib yam dab tsi lawv tsis xav ua.
Vim li cas kuv thiaj tsis tsim nyog tsim lub npe siv hauv facebook?
Muaj ntau qhov laj thawj vim li cas koj tab tom ntsib qhov tsis tsim nyog los tsim lub npe siv yuam kev rau koj nplooj Facebook. Tus neeg siv lub npe koj xav tau twb raug coj los ntawm lwm tus neeg siv. Koj tus username luv dhau los yog ntev dhau lawm.
Thaum twg siv hydrostatics?
Hauv kev siv, cov ntsiab lus ntawm hydrostatics yog siv rau teeb meem ntsig txog kev siab hauv dej tob(siab nce nrog qhov tob) thiab siab hauv huab cua (siab tsawg nrog qhov siab). hydrostatics tseem ceeb nyob qhov twg? Hydrostatics yog ib pawg ntawm cov kua dej statics, uas yog kev kawm ntawm txhua cov kua, ob qho tib si compressible los yog incompressible, thaum so.
Yuav ua li cas paintings xav tsim yog vim li cas?

Vim li cas lub khoos phis tawj pab tsim tsim tseem ceeb?
Nws pab cov neeg siv tsim qauv hauv 2D lossis 3D komlawv tuaj yeem pom kev tsim kho. CAD tso cai rau kev txhim kho, hloov kho, thiab ua kom zoo ntawm cov txheej txheem tsim. … Ua tsaug rau CAD, engineers tuaj yeem ua tus sawv cev kom raug ntau dua thiab hloov kho tau yooj yim los txhim kho kev tsim qauv zoo.
