Nws yog tus kawm ntawm cov khoom uas nyob so, los yog txav mus tas li. Statics yog tseem ceeb nyob rau hauv kev txhim kho cov kev txawj daws teeb meem. Nws qhia koj kom xav txog seb lub zog thiab lub cev ua li cas thiab ua rau ib leeg.
Tsuas yog li ntawd, vim li cas nws thiaj tseem ceeb rau kev kawm engineering mechanics?
Engineering mechanics yog daim ntawv thov ntawm mechanics los daws cov teeb meem uas muaj feem ntau engineering cov ntsiab lus. Lub hom phiaj ntawm qhov no Engineering Mechanics chav kawm yog nthuav qhia cov tub ntxhais kawm txog teeb meem hauv mechanics raws li siv rau plausibly real-world scenarios.
Ib tug kuj yuav nug, dab tsi yog statics hauv engineering mechanics? Statics yog ceg ntawm mechanics uas yog kev txhawj xeeb nrog kev tsom xam ntawm cov loads (force thiab torque, lossis "moment") ua rau lub cev tsis muaj kev nrawm (a = 0), tab sis, yog, nyob rau hauv static equilibrium nrog lawv ib puag ncig.
Ib sab saum toj no, dab tsi yog qhov tseem ceeb ntawm mechanics?
Tsis muaj teeb meem dab tsi koj nyiam hauv science lossis engineering, mechanics yuav yog tseem ceeb rau koj - tsab ntawv tsa suab yog lub tswv yim tseem ceeb hauv txhua qhov kev tshawb fawb. Mechanics tuaj yeem muab faib ua 2 thaj chaw - kinematics, cuam tshuam nrog kev piav qhia cov lus tsa suab, thiab cov dynamics, cuam tshuam nrog qhov ua rau ntawm kev txav.
Engineering mechanics yog dab tsi thiab koj yuav faib nws li cas?
Raws li cov lus tsa suab: Raws li cov lus tsa suab, mechanics muab faib ua ob pawg xws li statics thiab dynamics. Statics cuam tshuam nrog cov khoom thaum so thaum dynamics cuam tshuam nrog cov khoom hauv kev txav. Lub dynamics yog ntxiv subdivided rau hauv ob yam xws li kinetics thiab kinematics.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?
Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells
Dab tsi yog qhov tseem ceeb ntawm kev tawm hauv cov crystal kev loj hlob tsis muaj kev cuam tshuam?
Nws yog ib qho tseem ceeb uas yuav tsum tau ua kom qhov kev sim npog kom tsis txhob muaj plua plav thiab lwm yam khoom siv tsis xav tau los ntawm kev cuam tshuam kev loj hlob siv lead ua. Saib xyuas kev tsim cov muaju ntawm cov hlua txhua hnub. Sab laug tsis muaj kev cuam tshuam, cov muaju yuav tsum loj dua txhua hnub kom txog thaum cov tshuaj qhuav qhuav
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 yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov tseem ceeb ntawm kev siv mechanics hauv kev ua haujlwm?
Nyob rau hauv cov tswv yim sciences, siv mechanics muaj txiaj ntsig hauv kev tsim cov tswv yim tshiab thiab kev xav, nrhiav pom thiab txhais cov xwm txheej, thiab tsim cov cuab yeej sim thiab suav
