Qhov ntim ntawm a lub tog raj kheej yog lub square ntawm nws lub voj voog lub sij hawm pi lub sij hawm qhov siab. Yog li lub ntim ntawm koj khoob lub tog raj kheej yog (22)(pi)(4) -(1.52)(pi)(4). Qhov no yog hais txog 22 cubic feet. Yog koj lub tog raj kheej yog ua los ntawm pob zeb, uas feem ntau yog hais txog 144lbs ib cubic feet, ces nws yuav hnyav Luas = 22 x 144 = 3168 lbs.
Tsis tas li ntawd nug, tus qauv rau kev xam cov khoom hnyav yog dab tsi?
- SS daim ntawv. Length (Mtr) X Width (Mtr) X Thick(mm) X 8 = WeightPer Piece.
- XOV XWM. Luas (KGS) = LENGTH (MM) X BREADTH (MM) X0.
- Daim ntawv tooj liab. Luas (KGS) = LENGTH (MM) X BREADTH (MM) X0.
- ALUMINIUM NTAWV. Luas (KGS) = LENGTH (MM) X BREADTH (MM) X0.
- ALUMINIUM PIPE.
Qhov thib ob, peb tuaj yeem suav qhov hnyav li cas? Cov kauj ruam
- Txij li qhov hnyav yog lub zog, cov kws tshawb fawb kuj sau qhov sib npaug asF = mg.
- F = cim rau qhov hnyav, ntsuas hauv Newtons, N.
- m = cim rau qhov hnyav, ntsuas hauv kilograms, lossis kg.
- g = cim rau gravitational acceleration, qhia asm/s2, los yog meters ib ob squared.
Tsis tas li ntawd, koj yuav xam qhov hnyav ntawm cov pa roj li cas?
Txhawm rau txiav txim siab molecular hnyav ntawm a gas , peb ntsuas qhov ntim, qhov kub thiab txias ntawm aknown pawg ntawm a gas . Peb tuaj yeem siv Lub Tswv Yim Roj Law rau xam tus naj npawb ntawm moles gas peb muaj, thiab ces faib tus lej no rau hauv pawg kom tau txais cov thev naus laus zis hnyav.
Qhov hnyav ntawm steel yog dab tsi?
Raws li theoretical nominal hnyav thiab kwv yees kwv yees; siv rau kwv yees xwb. Qhov hnyav percubic nti (Density) ntawm hlau yog.2904lb.

Yuav ua li cas koj pom tag nrho qhov chaw ntawm lub tog raj kheej hollow?
Ib lub tog raj kheej yog ib qho khoom uas muaj ib qho sib xws, ncig-seem. Curved cheeb tsam ntawm ib lub tog raj kheej = 2 π rh. Tag nrho qhov chaw ntawm lub tog raj kheej = 2 π r h + 2 π r2 Curved deg cheeb tsam ntawm lub tog raj kheej hollow = 2 π R h + 2 π r h. Tag nrho qhov chaw ntawm lub tog raj kheej hollow = 2 π R h + 2 π r h + 2 (π R2 − πr2)
Yuav ua li cas koj pom qhov ntim ntawm cov dej hauv ib lub tog raj kheej kawm tiav?
Ncuav dej txaus los ntawm koj lub khob rau hauv lub tog raj kheej kawm tiav kom ncav cuag qhov siab uas yuav npog cov qauv. Nyeem thiab sau lub ntim. Tig me ntsis lub tog raj kheej tiav thiab ua tib zoo muab cov qauv tso rau hauv dej. Muab lub cylinder kawm tiav rau ntawm lub rooj thiab saib cov qib dej
Yuav ua li cas koj pom qhov loj ntawm lub tog raj kheej hollow?
Lub tog raj kheej hollow yog ua los ntawm kub. Qhov loj ntawm cov khoom yog ?? = 702.24 ???? thiab lub ntim ntim los ntawm sab nraud ntawm lub tog raj kheej yog ???????????? = 49.28 ∙ 10−3 ??3
Yuav ua li cas koj pom qhov lateral thiab deg cheeb tsam ntawm ib lub tog raj kheej?
Txhawm rau nrhiav thaj chaw sab nraud, peb pom qhov perimeter, uas nyob rau hauv rooj plaub no yog qhov ncig (qhov kev ncua deb ntawm lub voj voog), ces muab nws los ntawm qhov siab ntawm lub tog raj kheej. C sawv cev rau ib ncig, d sawv cev rau txoj kab uas hla, thiab lub cim pi yog sib npaug rau 3.14
Yuav ua li cas koj pom qhov ntim ntawm lub khob hliav qab hauv lub tog raj kheej?
Cov mis rau qhov ntim ntawm lub tog raj kheej yog v = πr2h. Qhov ntim rau lub khob hliav qab uas nws lub vojvoog yog R thiab qhov siab yog H yog V = 1/3π R2H
