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).
