Tributary loading or tributary width is the acquulation of loads that are directed toward a particular structural member. Piv txwv li: Tributary dav yog 7 ft + 5 ft=12 ft. Yog hais tias lub load yog 100 PSF, lub load rau lub beam yuav yog 12 ft x 100 PSF=1200 PLF.
tributary dav yog dab tsi?
Qhov dav dav rau B1 yog qhov kev ncua deb ntawm kab nruab nrab ntawm kab mus rau ib nrab ntawm qhov kev ncua deb mus rau tom ntej lossis kab teeb uas nyob ib sab, thiab thaj chaw tributary rau kab teeb yog thaj chaw bordered los ntawm tributary dav thiab qhov ntev ntawm lub beam, raws li ntxoov ntxoo nyob rau hauv daim duab.
Yuav ua li cas koj pom qhov dav tributary ntawm lub girder?
Graphically, peb tuaj yeem kos ib kab hauv nruab nrab ntawm txhua qhov kev txhawb nqa joist thiab hais tias tag nrho cov cheeb tsam ntawm kab thiab lub girder yog tributary rau lub girder. Koj tuaj yeem pom qhov no hauv daim duab TA. 2.6. Txoj kev deb ntawm cheeb tsam tributary nyob rau hauv cov kev taw qhia ntawm joists yog tributary dav.
Koj pom thaj chaw tributary ntawm ib kab li cas?
Yuav daws qhov teeb meem no, peb tuaj yeem txheeb xyuas txhua kab ntawm cov neeg nyob ze, thiab faib qhov kev ncua deb hauv ib nrab los ntawm kos ib kab nruab nrab. Lub cheeb tsam ntawm kab sab ntawm kab nruab nrab yuav yog nws 'tributary cheeb tsam.
Txoj kev hauv cheeb tsam tributary yog dab tsi?
Tributary area cheeb tsam nyob ib ncig ntawm kem uas yog bounded los ntawm ib tug vaj huam sib luag centerline. Txhawm rau xam cov quab yuam thiab cov khoom zoo li qub tau hloov pauv los ntawm cov slabs hauv pem teb mus rau txhua kab hauv cheeb tsam txoj kev siv.

Yuav ua li cas thiaj nrhiav tau qhov normalization tas li ntawm yoj ua haujlwm?
Qhov normalized nthwv dej-ua haujlwm yog li ntawd: Piv txwv 1: Ib qho particle yog sawv cev los ntawm kev ua haujlwm nthwv dej: qhov twg A, ω thiab a yog qhov tsis tu ncua. Qhov tsis tu ncua A yog yuav tsum tau txiav txim. Piv txwv 3: Normalize the wave function ψ=Aei(ωt-kx), qhov twg A, k thiab ω yog qhov zoo tiag tiag .
Yuav ua li cas thiaj nrhiav tau qib ntawm qhov tseem ceeb?
txhawm rau nrhiav qhov tseem ceeb, rho tus lej qhia los ntawm ib qho. Piv txwv li, tus nqi ntawm ". 01" txhais tau tias muaj 99% (1-. 01= . Koj pom qhov theem ntawm qhov tseem ceeb hauv kev ntsuas kev xav li cas? theem tseem ceeb, kuj txhais tau tias yog alpha lossis α, yog qhov tshwm sim ntawm kev tsis lees paub qhov kev xav tsis tseeb thaum nws muaj tseeb.
Yuav ua li cas thiaj nrhiav tau qhov chaw pib ntawm ib qho particle?
Txoj Haujlwm Formula - Hloov ntawm Txoj Haujlwm Tus Qauv & Piv Txwv Δr=r2 - r1. Yog hais tias qhov kev hloov ntawm txoj hauj lwm yog nyob ntawm lub sij hawm, ces txoj hauj lwm tuaj yeem sawv cev ua. r (t)=½ at2 + ut + r1. r=thawj txoj haujlwm.
Yuav ua li cas thiaj nrhiav tau qhov piv txwv ntsuas ntsuas?
Scale factor: Larger daim dimensions ÷ Daim duab me meQhov ntsuas qhov ntsuas rau qhov ntsuas yog ib txwm ntau dua 1. Piv txwv li, yog tias qhov loj ntawm daim duab loj yog 15 thiab uas tus me dua yog 5, cia peb tso qhov no rau hauv cov qauv uas ua rau nws:
Yuav ua li cas thiaj nrhiav tau lub qhov raccoon?
feem ntau koj tuaj yeem pom raccoon dens hauv qhov khoob ntawm tsob ntoo lossis cav lossis ib qho chaw ruaj ntsegLawv xav tau kev sov so thiab kev tiv thaiv kom ciaj sia lub caij ntuj no. Hauv cov nroog, koj tuaj yeem pom lawv hauv cov cua daj cua dub thiab lwm qhov me me.
