Cov cuab yeej txiav, ntsuas cov cuab yeej, pwm, thiab lwm yam siv hauv kev tsim khoom siv tshuab yuav tsum muaj qhov nyuaj txaus kom ntseeg tau tias lawv qhov kev ua tau zoo thiab kev ua neej nyob. Hnub no, kuv yuav tham rau koj txog lub ntsiab lus ntawm "hardness".
Hardness yog ib qho kev ntsuas ntawm cov khoom muaj peev xwm tiv thaiv lub zos deformation, tshwj xeeb tshaj yog cov yas deformation, indentation, los yog khawb. Feem ntau, cov khoom siv nyuaj, qhov zoo dua nws hnav tsis kam. Piv txwv li, mechanical Cheebtsam xws li cov iav yuav tsum tau ib tug tej yam kev mob ntawm hardness los xyuas kom meej txaus hnav tsis kam thiab kev pab lub neej.
