Kev nyab xeeb rauj, txhua leej txhua tus yuav tsum muaj paj tawg rau hauv daim ntawv cog lus.Hauv thaum muaj xwm ceev, koj tuaj yeem khiav tawm ntawm lub qhov rais.Qhov kev nyab xeeb rau kev nyab xeeb kuj yog hu ua lub txaj muag cawm siav.Nws yog cov neeg cog khoom hauv lub tsheb thiab lwm qhov chaw uas yooj yim nkag tau yooj yim.Hauv thaum muaj xwm ceev xws li hluav taws los yog lub tsheb ntog mus rau hauv dej, nws yog qhov yooj yim mus tawm thiab tsoo qhov iav qhov rooj qhov rooj kom dim.Tab sis koj puas paub yuav ua li cas thiaj tawg tsoo lub qhov rais? Koj puas paub ua li cas puas tsoo lub qhov rais? Koj puas ua li cas txoj kev nyab xeeb-khi nws txawv ntawm ib txwm rauj?
Cov khoom siv ntawm cov qhov rais uas niaj hnub no feem ntau tempered iav. Lub zog tensile thiab kev ua haujlwm ntawm cov iav tempered yog ob peb zaug siab tshaj qhov iav uas zoo tib yam, thiab nws tsis yooj yim rau kev tawg lawm.Txawm yog tias nws yog lawm, nws yuav tsis tawg mus rau hauv daim ntse , tab sis tawg lawm.Compared nrog zoo tib yam iav, kev puas tsuaj rau tib neeg lub cev zoo heev txo thiab kev ruaj ntseg siab.Vim li ntawm cov yam ntxwv, tempered iav feem ntau yog siv nyob rau hauv lub qhov rais, muab faib phab ntsa thiab txee qhov rooj.Tau kawg, tempered iav muaj cov ribs, qhov nruab nrab ntawm qhov uas muaj zog tshaj plaws, thiab plaub lub kaum pob zeb thiab npoo yog qhov tseem ceeb tshaj plaws.Ordinary ca iav, xws li daim iav siv rau hnub ua hauj lwm, yog qhov yuam kev.Yog hais tias koj xav khoo nws, nws yuav tu nrho thaum koj siv yam cuab yeej siv coj los rhaub nws ntawm yuav.Qhov zoo tshaj plaws los khob qhov iav nrog kev nyab xeeb rauj.Cov plaub thiab plaub fab, tshwj xeeb tshaj yog cov khoom siv nruab nrab ntawm cov ntug ntawm iav. Yog tias koj nrog nws ib qho kev rauj, nws yuav txav tsis tau.Thaum th yog lub sij hawm,
nws yog ib qhov tsim nyog yuav tau pom kev nyab xeeb.
Physics qhia rau peb tias thaum muaj qee qhov kev quab yuam ua rau ib qho chaw, qhov chaw me me, qhov kev pom tseeb ntawm qhov siab, thiab quab yuam ib square meter, uas yog, qhov siab, thiab quab yuam ib square meter, uas yog , lub siab tseem ntau dua.Thaum tus rauj siv rau pry lub khob, vim hais tias thaj chaw ntawm qhov taub me me, lub siab ntawm tus taw tes tiv thaiv yog tus loj, thiab nws yog yooj yim qhib lub ceeb tshaj.For tempered iav, kab laug sab heev heev ntawm cov kab nrib pleev nplawm yog tsim nyob hauv ib qho tseem ceeb, thiab cov iav tawg tuaj yeem raug tshem tawm los ntawm maj mam txhuam nws nrog ib tug rauj.
