Kodi Kulimba Kwambiri ndi Mphamvu Zokolola ndi Chiyani?

Chilichonse chogwiritsidwa ntchito ndi mphamvu yowonjezera kapena yokhazikika yakunja pamapeto pake idzadutsa malire ndikuwonongeka. Pali mitundu yambiri ya mphamvu yakunja yomwe imayambitsa kuwonongeka kwa zinthu, monga kupanikizika, kupanikizika, kumeta ubweya, ndi torsion. Mphamvu ziwirizi, kulimba kwamphamvu ndi kutulutsa mphamvu, ndi zamphamvu zokha.
Mphamvu ziwirizi zimapezeka kudzera m'mayesero amphamvu. Zinthuzo zimatambasulidwa mosalekeza pamlingo wodziwika bwino mpaka zitasweka, ndipo mphamvu yayikulu yomwe imakhala nayo ikathyoledwa ndiye katundu womaliza wazinthuzo. Kuchuluka kwamphamvu kwambiri ndikuwonetsa mphamvu, ndipo gawoli ndi Newton (N). Chifukwa Newton ndi kagawo kakang'ono, nthawi zambiri, ma kilonewtons (KN) amagwiritsidwa ntchito, ndipo katundu womaliza amagawidwa ndi chitsanzo. Kupsinjika komwe kumabwera kuchokera kugawo loyambilira la magawo osiyanasiyana kumatchedwa mphamvu yamakomedwe.

Zimayimira kuthekera kwakukulu kwa chinthu kukana kulephera pansi pazovuta. Ndiye mphamvu zokolola ndi chiyani? Mphamvu zokolola zimangotengera zida zotanuka, zida za inelastic zilibe mphamvu zokolola. Mwachitsanzo, mitundu yonse ya zida zachitsulo, mapulasitiki, labala, ndi zina zotero, zonse zimakhala ndi mphamvu komanso zokolola. Magalasi, zoumba, zomangira, ndi zina zotero nthawi zambiri zimakhala zosasunthika, ndipo ngakhale zipangizo zoterezi zimakhala zotanuka, zimakhala zochepa. Zinthu zotanuka zimayikidwa ndi mphamvu yakunja mosalekeza komanso mosalekeza mpaka itasweka.
Kodi kwenikweni chasintha n’chiyani? Choyamba, zinthuzo zimakhala ndi deformation zotanuka pansi pa mphamvu yakunja, ndiye kuti, zinthuzo zidzabwereranso kukula kwake ndi mawonekedwe ake pambuyo pochotsa mphamvu yakunja. Pamene mphamvu yakunja ikupitiriza kuwonjezeka ndikufika pamtengo wina, zinthuzo zidzalowa mu nthawi ya pulasitiki. Zinthu zikangolowa kusinthika kwa pulasitiki, kukula koyambirira ndi mawonekedwe azinthu sizingabwezeretsedwenso mphamvu yakunja ikachotsedwa! Mphamvu ya mfundo yovuta yomwe imayambitsa mitundu iwiriyi ya mapindikidwe ndi mphamvu zokolola zakuthupi. Mogwirizana ndi mphamvu yogwiritsira ntchito mphamvu, mphamvu yowonongeka ya mfundo yovutayi imatchedwa mfundo yokolola.
