Cov neeg tsim khoom tau paub dhau los hu cov ntaiv ntawm txhua yam qauv ntawm kev raug mob ntxiv, tsis hais hnub nyoog ntawm cov neeg nyob hauv. Ntawm cov kauj ruam uas dav dhau thiab siab, nws yooj yim rau dawm, thiab ntawm qhov nqaim koj tuaj yeem plam. Yog li ntawd, pib tsim lub tsev, tus builder xam nyob rau hauv ua ntej qhov ntev ntawm lub staircase lug. Nrog rau kev xam kom raug, qhov kev pheej hmoo ntawm kev raug mob tuaj yeem txo qis.
Yuav ua li cas xam tus kauv staircase? Pib qhov twg?
Qhov siab ntawm cov kauj ruam uas tsim nyog tshaj plaws rau kev taug kev sib raug rau 15-20 centimeters. Taug kev ntawm cov kauj ruam no, tus neeg, tsis hais hnub nyoog thiab qhov siab, yuav muaj kev ntseeg siab.
Lwm qhov tseem ceeb yog xam qhov dav ntawm cov kauj ruam. Raws li qhov tseeb tias qhov nruab nrab qhov loj ntawm tib neeg ko taw yog 20 centimeters, qhov yooj yim tshaj plaws rau kev taug kev yog cov ntaiv, qhov twg qhov dav thiab qhov siab ntawm cov kauj ruam sib haum rau cov kev txwv saum toj no.
Yuav ua li cas xam tus kauv staircase mus rau pem teb thib ob?
Top txoj kev npaj ntawm cov ntaivzoo li lub voj voog, qhov siab thiab qhov dav ntawm qhov sib thooj rau qhov zoo sib xws ntawm qhov qhib ntawm cov plag tsev. Yog hais tias lub vojvoog ntawm qhov qhib feem ntau qhia los ntawm tsab ntawv Latin r, ces lub cim r1 cim lub vojvoog ntawm cov yeeb nkab txhawb nqa, ntawm cov kauj ruam ntawm cov kauj ruam ntawm cov staircase yog ib feem ntawm kev txhawb nqa. Yuav ua li cas xam lub vojvoog ntawm qhov sib npaug ntawm cov ntaiv?
Cov lus qhia los ntawm cov neeg tsim khoom caij nyoog
Lub kauv staircase yog zoo li lub khob hliav qab, xam nws qhov dav, cov neeg tsim khoom siv cov qauv lej. Ib tug neeg uas nyob deb ntawm kev tsim kho thiab lej, pib suav, yuav ntsib teeb meem tam sim ntawd. Nrog xws li, piv txwv li, raws li xam qhov ncig ntawm ib tug kauv staircase. Yuav ua li cas xam txhua yam kom raug thiab zam kev yuam kev? Cov kws tshaj lij tiv thaiv txoj haujlwm no siv cov qauv:
2 x 3, 14 x r (qhov no, r yog qhov dav ntawm tus ntaiv).
Tib qauv siv tau los ntawm cov neeg nyob hauv lub caij ntuj sov uas tau teeb tsa nws tus kheej lub hom phiaj ntawm kev tsim cov staircase nrog nws txhais tes. Nws yuav muaj peev xwm xam qhov loj ntawm lub voj voog ntawm qhov ntev yam tsis muaj kev pab sab nraud, tau txiav txim siab qhov dav ntawm tus qauv.
Yog hais tias, piv txwv li, puag ncig qhov dav mus rau 100 centimeters, ces qhov ncig ntawm lub davhlau ntawm cov ntaiv yog 628 centimeters.
txhawm rau xam qhov siab ntawm lub davhlau ntawm ntaiv (thaum saib los ntawm sab nraud ntawm tus ntaiv, lub davhlau yuav zoo li cov qauv ruaj khov), lub voj voog yuav tsum muab faib los ntawm cov kauj ruam nyob rau hauv lub davhlau. Piv txwv li, yog tias 10 kauj ruam tau npaj, ces qhov kev ncua deb yuav yog 62.8centimeter (628: 10).
Cov kws tshaj lij kws tshaj lij qhia: ua ntej pib nrog cov lus qhia meej, nws yog qhov tsim nyog los txiav txim siab tag nrho qhov ntev ntawm cov qauv.
qauv qhov siab thiab lwm yam ntsiab lus tseem ceeb
Yog tias tus neeg tsim kho tshiab tuaj yeem txiav txim siab qhov siab ntawm cov ntaiv yam tsis muaj kev pab sab nraud (qhov siab ntawm cov qauv ntsia hlau tau txiav txim siab tib yam li qhov ntev ntawm cov staircases - los ntawm qhov siab ntawm chav), ces nrhiav tawm qee cov ntsiab lus zoo li tsis tseem ceeb tuaj yeem coj nws mus rau qhov kawg. Piv txwv li: ntawm lub kaum sab xis ntawm lub voj voog staircase puag ncig, yuav ua li cas los xam tus naj npawb ntawm cov kauj ruam, leej twg ntawm lawv yuav raug suav hais tias yog thawj, thiab qhov twg - qhov kawg?
Txoj kab nqes uas tau txais txiaj ntsig zoo tshaj plaws ntawm tus ntaiv kauv, raws li cov kws tshaj lij, yuav tsum tsis pub tshaj 37 degrees. Tus nqi qis qis yuav tsum tsis pub tsawg dua 23 degrees. Nce tus ntaiv, tus neeg yuav tsis sib npaug ntawm cov kauj ruam, tab sis yuav proportionally txav mus rau pem hauv ntej thiab nce. Los ntawm kev ua kom lub kaum sab xis ntawm txoj kev xav, tus tswv tsev yuav txuag tau qhov chaw siv tau rau cov qauv, tab sis yuav tig cov stairs li niaj zaus nce mus rau qhov nce ntawm qhov nyuaj.
Raws li tus lej ntawm cov kauj ruam. Ua ntej, tus tsim yog txiav txim siab nrog lawv qhov siab (feem ntau nws yog 15-25 centimeters) thiab qhov dav ntawm ob lub qab nthab. Piv txwv li, yog hais tias qhov siab ntawm lub qab nthab nyob rau hauv thawj pem teb yog 2 meters 70 centimeters, lub thickness thiab qhov siab ntawm cov kauj ruam yog 20 thiab 22 centimeters, feem, thiab lub thickness ntawm lub qab nthab nyob rau hauv pem teb ob yog 15 centimeters.qhov no txhais tau hais tias qhov siab ntawm tag nrho cov qauv yuav yog 2 meters 85 centimeters, thiab tus naj npawb ntawm cov kauj ruam yuav sib raug rau tus lej 13.
Lub pem teb ntawm lub tsev thib ob yuav ua haujlwm ua cov kauj ruam saum toj kawg nkaus. Hauv pem teb ntawm thawj pem teb yog suav tias yog xoom kauj ruam.
