Iav yog ib qho nyuaj thiab cov khoom siv loj. Txawm li cas los xij, ntev li nws tau yaj ntawm qhov kub thiab txias thiab tom qab ntawd tawm los ntawm cov qhov me me rau hauv cov iav zoo heev, cov khoom siv hloov tau yooj yim heev. Tib yam yog iav, vim li cas thiaj li ib txwm yog iav nyuaj thiab nkig, thaum lub fibrous iav yog hloov tau thiab yoog raws? Qhov no yog tau zoo piav qhia los ntawm cov hauv paus ntsiab lus geometric.
Xav tias khoov rau hauv tus pas (kev kwv yees tsis muaj kev tawg), thiab sab sab nraud yog ncab, thiab qhov loj ntawm lub axis yuav luag tsis hloov. Thaum khoov nyob rau ntawm tib lub kaum sab xis, lub thinner tus pas, qhov tsawg dua sab nraud yog ncab thiab sab hauv yog compressed. Hauv lwm lo lus, lub thinner, me dua rau hauv lub zos tensile lossis compressive deformation rau tib qib ntawm khoov. Cov khoom siv twg tuaj yeem yauv mus rau qee qhov kev ua haujlwm tsis tu ncua Thaum cov iav fiber yog lo txaus, txawm tias muaj kev loj hlob loj tshwm sim, cov qib ntawm cov kabmob me me, yog li nws yuav tsis tawg.
