Qhov tshwj xeeb nruj thiab cuam tshuam lub zog nqus lub peev xwm ntawm cov hlau ua npuas ncauj yog qhov tseem ceeb ntawm kev siv cov hlau ua npuas ncauj. Ntau yam ntawm modulus ntawm elasticity tuaj yeem tau txais los ntawm kev xaiv ntawm cov khoom ua npuas dej, kom cov lus teb xav tau tuaj yeem sib phim thiab cov teeb meem tsis zoo yuav raug tshem tawm thiab tshem tawm. Hom kev siv ntawm lub zog nqus yog buffers thiab shock absorbers. Cov ntaub ntawv kuj tseem siv dav hauv cov tsheb thauj khoom rau tsheb, buffers rau nqa thiab thauj cov tshuab, lub zog nqus cov khoom siv rau cov tshuab, thiab lwm yam.
