Ntau txhais ntawm Tus qauv tsim
Tus qauv tsim txhais tau tias ib feem ntawm lub moj khaum-ua haujlwm ntawm lub tsev lossis lwm yam qauv . Cov cov yam ntxwv ntawm cov khoom ntawm ib lub tsev sab nrauv phab ntsa muaj xws li ntsug studs, sab saum toj thiab hauv qab daim hlau, thiab qhov rais thiab qhov rooj sills thiab headers
Tsuas yog li ntawd, dab tsi yog cov yam ntxwv ntawm lub tsev?
Niaj hnub no peb yuav pib nrog cov khoom siv: Foundation, Framing, thiab Roof
- Foundation. Cov tsev feem ntau yog tuav los ntawm cinder blocks nyob rau sab nrauv, phab ntsa ntawm lub tsev.
- Ncej. "Lawv ua lub tsev ntawd hauv 2 hnub!" Nws yog amazing npaum li cas ceev cov ntoo framing ntawm ib lub tsev tuaj yeem pop tuaj, puas yog?
- Rooj.
lub ru tsev puas yog ib qho khoom siv ntawm lub tsev? Cov khoom siv hauv tsev tshwj xeeb kev tsim vaj tsev cov khoom tsim, engineered thiab manufactured nyob rau hauv kev tswj tej yam kev mob rau ib tug tshwj xeeb daim ntawv thov. Piv txwv yog ntoo lossis hlau lub ru tsev trusses, pem teb trusses, pem teb panels, I-joists, los yog engineered beams thiab headers.
Hais txog qhov no, dab tsi yog ib co structural Cheebtsam?
Cov qauv tsim
- Qws - axial loads.
- Beam - axial thiab dabtsi yog khoov loads.
- Struts los yog Compression cov tswv cuab - compressive loads.
- Ties, Tie rods, eyebars, txiv leej tub-wires, suspension cables, los yog hlau ropes - nro loads.
Dab tsi yog qhov kev kho vaj tse?
Kev kho vaj tse txhais tau tias kho mus rau tus qauv cov tswv cuab ntawm lub ru tsev, lub hauv paus, cov slabs hauv pem teb thiab cov phab ntsa sab nrauv mus tas li thiab cov kab kev txhawb nqa ntawm Lub Tsev. Kev kho vaj tse txhais tau tias ib yam kho mus rau qauv ntawm lub tsev (nrog rau lub hauv paus thiab lub ru tsev) yuav tsum tau los ntawm lub sijhawm.

Dab tsi yog qhov sib txawv loj ntawm kev sib tham kev yuav khoom thiab kev sib tw sib tw yuav khoom?
Dab tsi yog qhov sib txawv loj ntawm kev sib tham kev yuav khoom thiab kev sib tw sib tw yuav khoom? Hauv kev sib tham txog kev yuav khoom, lub tuam txhab kev ruaj ntseg issuer thiab tus thawj tswj hwm kev nqis peev hauv tuam txhab lag luam sib tham txog tus nqi uas tus tuam txhab lag luam yuav them tus neeg xa khoom rau qhov kev tso nyiaj tshiab
Puas yog acetic acid yog sib xyaw lossis sib xyaw?
Nws yog ib qho organic compound uas tau muab cais ua acarboxylic acid vim tias pawg carboxyl (-COOH) muaj nyob hauv nws cov qauv tshuaj. Acetic acid kuj tseem hu ua lub secondimplest carboxylic acid. Acetic acid yog nrov tshaj plaws vim nws siv hauv vinegar
Puas yog kev lag luam sib xyaw thiab kev tshaj tawm sib xyaw ua ke?
Kev sib xyaw ua lag luam thiab kev tshaj tawm sib xyaw muaj qhov sib txawv, thiab ob qho tib si tseem ceeb rau koj txoj kev lag luam. Thaum koj txheeb xyuas koj qhov kev lag luam sib xyaw, nws yuav pab koj txiav txim siab yuav ua li cas kom txaus siab rau koj cov neeg siv khoom, thaum kev sib tw tshaj tawm tsom rau kev sib cuam tshuam ncaj qha rau cov neeg siv khoom
Tus neeg twg tau soj ntsuam kev mloog lus ntawm kev sib raug zoo los ntawm kev ua ib qho kev sim uas yuav tsum muaj cov tub ntxhais kawm cov ntsiab lus los tswj cov kev mob siab rau cov ntsiab lus hauv kev tshuaj xyuas kev kawm?
Milgram Shock Experiment Ib qho ntawm cov kev tshawb fawb nto moo tshaj plaws ntawm kev mloog lus hauv kev puas siab puas ntsws tau ua los ntawm Stanley Milgram, tus kws kho mob hlwb ntawm Yale University. Nws tau ua ib qho kev sim qhia txog qhov tsis sib haum xeeb ntawm kev mloog lus rau txoj cai thiab lub siab ntawm tus kheej
