Mawu a Olimpiki - Citius, Altius, Fortius - Latin ndi apamwamba, amphamvu komanso othamanga - amalankhulana pamodzi mu Chingerezi, zomwe nthawi zonse zakhala zikugwiritsidwa ntchito pamasewera a Olimpiki ndi Paralympic. Pamene opanga zida zamasewera ambiri akugwiritsa ntchito zinthu zophatikizika, mawuwa tsopano akugwiritsidwa ntchito pa nsapato, njinga, ndi zinthu zambiri zomwe opikisana nawo masiku ano amagwiritsa ntchito.
Zinapezeka kuti zipangizo zomwe zingawonjezere mphamvu ndikuchepetsa kulemera kwa zida zomwe zimagwiritsidwa ntchito ndi othamanga zimatha kufupikitsa nthawi ndikuwonjezera magwiridwe antchito.

Kukwera bwato

Kugwiritsa ntchito Kevlar, yomwe imagwiritsidwa ntchito kwambiri poteteza zipolopolo m'ma kayak, kungapangitse kuti kapangidwe ka bwato kakhale kolimba popanda kusweka ndi kusweka. Graphene ndi ulusi wa kaboni zimagwiritsidwa ntchito m'mabwato ndi m'mabwato kuti ziwonjezere mphamvu ndikuchepetsa kulemera, komanso kuwonjezera kutsetsereka.

Gofu

Poyerekeza ndi zipangizo zachikhalidwe, ma nanotubes a carbon (CNT) ali ndi mphamvu zambiri komanso kuuma kwapadera, kotero nthawi zambiri amagwiritsidwa ntchito mu zida zamasewera. Wilson Sporting Goods Co. yagwiritsa ntchito nanomaterials kupanga mipira ya tenisi kuti ithandize mipira kusunga mawonekedwe ake mwa kuchepetsa kutayika kwa mpweya ikagunda mpira ndikuupangitsa kuti ukhale wodumphadumpha kwa nthawi yayitali. Ma polima olimbikitsidwa ndi ulusi amagwiritsidwanso ntchito mu ma rackets a tenisi kuti awonjezere kusinthasintha ndikuwonjezera kulimba ndi magwiridwe antchito.

Ma nanotubes a kaboni amagwiritsidwa ntchito popanga mipira ya gofu ndipo ali ndi ubwino wa mphamvu, kulimba komanso kusawonongeka. Ma nanotubes a kaboni ndi ulusi wa kaboni amagwiritsidwanso ntchito m'makalabu a gofu kuti achepetse kulemera ndi mphamvu ya kalabu, pomwe akuwonjezera kukhazikika ndi kulamulira.

Kuponya mivi

Mbiri ya mauta ozungulira omwe ali ndi ma composite recurve imayamba zaka masauzande ambiri zapitazo, pamene matabwawo anali ophimbidwa ndi nyanga ndi nthiti kuti asavutike ndi kupsinjika. Uta wamakono uli ndi chingwe cha uta ndi chogwirira chokhala ndi zowonjezera zolunjika ndi mipiringidzo yokhazikika yomwe imachepetsa kugwedezeka muvi ukatulutsidwa.

Uta uyenera kukhala wolimba komanso wokhazikika kuti muvi utuluke pa liwiro loyandikira 150 mph. Zipangizo zopangidwa ndi zinthu zosiyanasiyana zimatha kulimbitsa izi.
