Kev faib tawm ntawm cov neeg kho tshuab cov khoom
Feem ntau hais tias cov khoom siv cav yog: elasticity, plasticity, txhav, lub hnub nyoog rhiab, lub zog, tawv, cuam tshuam toughness, nkees lub zog thiab pob txha tawv.
Elasticity: Thaum cov khoom siv hlau tsis txawv txav los ntawm sab nraud quab yuam, nws tuaj yeem kho nws lub qub qauv thaum lub zog sab nraud tshem tawm.
Yasity: Lub peev xwm ntawm cov khoom siv hlau los tsim cov kev hloov kho tas mus li yam tsis muaj kev puas tsuaj nyob rau hauv sab nraud quab yuam.
Ua kom nruj: Lub peev xwm ntawm cov khoom siv hlau los tiv thaiv elastic deformation thaum ntxhov siab.
Lub Zog: Muaj peev xwm ntawm cov khoom siv hlau los tiv thaiv kev deformation thiab puas hauv qab sab nraud.
Hardness: Lub peev xwm ntawm cov khoom siv hlau los tiv thaiv qhov ntxeem tau ntawm cov khoom tawv rau hauv nws.
Qhov cuam tshuam tawv tawv: Lub peev xwm ntawm cov khoom siv hlau los tiv thaiv qhov kev puas ntsoog ntawm cov nrawm.
Qaug zog lub zog: Qhov kev ntxhov siab tshaj plaws uas tsis ua rau tawg thaum cov khoom siv hlau tau raug rau ntau qhov rov ua dua los yog hloov pauv.
Cov pob txha tawv: qhov ntsuas qhov ua tau zoo siv los ua kom pom qhov muaj peev xwm ntawm cov khoom siv los tawm tsam kev tawg thiab tsis nthuav dav.
