L 0). Tensile stress thiab strain tshwm sim thaum lub zog yog ncab ib yam khoom, ua rau nws elongation, thiab qhov ntev hloov Δ L yog qhov zoo. Compressive stress thiab strain tshwm sim thaum lub zog sib cog lus ib yam khoom, ua rau nws shortening, thiab qhov ntev hloov Δ L yog tsis zoo. tensile stress=F ⊥ A.
Kev ntxhov siab tensile tshwm sim li cas?
Tensile stress yog ib lub xeev uas ib qho kev siv thauj khoom nyhav kom ncav cuag cov khoom hauv qhov axis ntawm cov ntawv thov, lossis lwm yam, nws yog qhov kev ntxhov siab los ntawm rub. cov khoom. … Tensile stress yog lub xeev kev ntxhov siab uas ua rau muaj kev nthuav dav.
Dab tsi ua rau tensile?
Tensile stress yog lub xeev kev ntxhov siab tshwm sim los ntawm ib qho kev thov load uas nyhav rau elongate cov khoom raws li axis ntawm cov ntaub ntawv load, nyob rau hauv lwm yam lus, kev nyuaj siab los ntawm rub lub khoom.

Koj paub li cas yog tias kev ntxhov siab yog tensile lossis compressive?
Qhov Sib Txawv Tseem Ceeb - Tensile vs Compressive Stress
Hom kev ntxhov siab yog txiav txim siab los ntawm kev siv lub zog ntawm cov khoom. Yog tias nws yog lub zog tensile (stretching), cov khoom muaj kev ntxhov siab. Yog hais tias nws yog compressive (squeezing) quab yuam, cov khoom muaj kev nyuaj siab.
Kev ntxhov siab tensile compressive stress yog dab tsi?
Tensile stress yog lub zog ib txwm muaj rau ib cheeb tsam(σ=F/A) uas ua rau ib qho khoom ua kom ntev. Compressive stress yog lub zog ib txwm nyob rau ib cheeb tsam (σ=F/A) uas ua rau ib qho khoom txo qhov ntev.
