Lub cev deformable . Hauv mechanics , ib lub cev uas hloov nws cov duab thiab / lossis ntim thaum raug ua los ntawm txhua yam kev quab yuam sab nraud.
Tsis tas li cov lus nug yog, vim li cas nws cov tshuab ntawm lub cev deformable yog qhov tseem ceeb rau kev kawm engineering?
Lub hom phiaj ntawm kev kawm cov mechanics ntawm lub cev deformable lub zog ntawm cov ntaub ntawv yog kom paub tseeb tias tus qauv tsim muaj kev nyab xeeb tiv thaiv kev sib xyaw ua ke ntawm kev siv zog thiab lub sijhawm.
Tsis tas li ntawd, dab tsi yog statics ntawm lub cev nruj? Statics yog ib ceg ntawm mechanics uas kawm txog cov teebmeem thiab kev faib tawm ntawm lub zog ntawm lub cev nruj uas yog thiab nyob twj ywm ntawm so. Nyob rau hauv cov cheeb tsam no ntawm mechanics, lub lub cev nyob rau hauv uas lub zog yog acting yog assumed nruj . Kev deformation ntawm cov tsis- lub cev nruj yog kho nyob rau hauv lub zog ntawm cov ntaub ntawv.
Hais txog qhov no, lub zog ntawm cov khoom siv yog dab tsi?
Txhais. Hauv mechanics ntawm cov ntaub ntawv , cov lub zog ntawm cov khoom Nws muaj peev xwm tiv taus ib qho kev thov tsis ua haujlwm lossis cov yas deformation. Teb ntawm zog ntawm cov ntaub ntawv cuam tshuam nrog lub zog thiab deformations uas tshwm sim los ntawm lawv cov yeeb yam ntawm a khoom.
Unit ntawm strain yog dab tsi?
Lim (Deformation) Nco ntsoov tias mob yog dimensionless chav tsev vim nws yog qhov piv ntawm ob qhov ntev. Tab sis nws kuj yog ib qho kev xyaum hais tias nws yog qhov piv ntawm ob qhov ntev units - zoo li m / m lossis hauv / hauv.

Dab tsi yog qhov txawv ntawm classical mechanics thiab quantum mechanics?
Nyob rau hauv luv luv, lub ntsiab sib txawv ntawm quantum thiab classical physics yog qhov txawv ntawm ib tug rampand ib staircase. Nyob rau hauv classical mechanics, cov xwm txheej (feem ntau) yog tas mus li, uas yog hais tias lawv txav mus rau hauv tus qauv, muaj kev sib haum xeeb thiab ua tau zoo. Qhov projectile motion yog ib qho piv txwv zoo ntawm classical mechanics
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Lub luag haujlwm ntawm lub cev thiab lub cev yog dab tsi?
Anatomy yog kev kawm txog cov qauv thiab kev sib raug zoo ntawm lub cev. Physiology yog kev kawm txog kev ua haujlwm ntawm lub cev thiab lub cev tag nrho
