B. Carneiro, tus tsim ntawm qhov kev sib tw nro rau kev ntsuas lub zog tensile ntawm pob zeb, tseem hu ua Brazilian xeem.

Dab tsi yog qhov kev xav ntawm tensile xeem?

Lub tswv yim yooj yim ntawm kev ntsuas tensile yog tso cov qauv ntawm cov khoom siv ntawm ob lub khoom siv hu ua "grips" uas clamp cov khoomCov khoom muaj qhov ntev, zoo li ntev thiab cheeb tsam hla ntu. Peb mam li pib siv qhov hnyav rau cov khoom tuav ntawm ib kawg thaum lwm qhov kawg yog tsau.

Tsim lub tensile yog dab tsi?

Kev ntsuas tensile, tseem hu ua kev ntsuas nruj, yog ib qho tseem ceeb tshaj plaws thiab ntau hom kev sim tshuab. Kev ntsuas tensile siv tensile (rub) quab yuam rau cov khoom siv thiab ntsuas cov qauv cov lus teb rau qhov kev ntxhov siab.

Leej twg tsim lub tshuab ntsuas universal?

Tinius Olsen nws tus kheej tau tsim thawj lub tshuab ntsuas thoob ntiaj teb hauv xyoo 1880 thiab, thoob plaws hauv keeb kwm, lub tuam txhab tau ua tus thawj coj ntawm kev txhim kho thiab kev tsim kho tshiab.

Kev ntsuas tensile ua li cas?

Tensile xeem yog cov txheej txheem kev sim ua kom puas tsuaj uas muab cov ntaub ntawv hais txog lub zog tensile, lub zog tawm los, thiab ductility ntawm cov khoom siv hlau. Nws ntsuas lub zog uas yuav tsum tau ua kom tawg cov khoom sib xyaw lossis cov qauv yas thiab qhov ntev npaum li cas cov qauv stretches lossis elongates mus rau qhov tawg
