Aliyense amene amapita kukasambira ndi galuyo amadziwa kuti ndi bwino kubwereranso masitepe angapo mnzako wa miyendo inayi atangotuluka m'madzi. Chifukwa galu wonyowa amayenera kudzigwedeza yekha poyamba. Ofufuza a ku Georgia Institute of Technology tsopano apeza mmene kugwedeza kulili kofunika kwambiri kwa nyama ndiponso kuchuluka kwa kugwedezekako kumasiyanasiyana malinga ndi nyama.
Ofufuzawo adafufuza za kugwedezeka kwa mitundu 17 ya nyama. Kuyambira mbewa mpaka agalu, anayeza kutalika ndi kulemera kwa nyama 33. Ndi kamera yothamanga kwambiri, ankajambula mmene nyamazo zikunjenjemera.
Iwo adawona kuti nyamazo zimayenera kudzigwedeza nthawi zambiri ngati zimapepuka.
Agalu akamanjenjemera, amasuntha chauko ndi chauko kasanu ndi katatu pa sekondi iliyonse. Zinyama zing'onozing'ono, monga mbewa, zimagwedezeka mofulumira kwambiri. Komano, chimbalangondo cha grizzly chimangogwedezeka kanayi pamphindikati. Zinyama zonsezi zimakhala zouma mpaka 70 peresenti pakangopita masekondi pang'ono pambuyo pa kuzungulira kwawo.
Kugwedeza kowuma kumapulumutsa mphamvu
Kwa zaka mamiliyoni ambiri, nyama zakhala zikuchita bwino kugwedezeka kwawo. Ubweya wonyowa umatsekereza bwino, kutuluka kwa madzi otsekeredwa kukhetsa mphamvu ndipo thupi limazirala msanga. “Chotero ndi nkhani ya moyo ndi imfa kukhala youma m’nyengo yozizira,” anatero David Hu, mkulu wa gulu lofufuza.
Ubweyawu umathanso kuyamwa madzi ambiri, zomwe zimapangitsa kuti thupi likhale lolemera. Mwachitsanzo, khoswe wonyowa amayenera kunyamula XNUMX peresenti ya kulemera kwa thupi lake mozungulira. Ndicho chifukwa chake nyama zimadzigwedeza zouma kuti zisawononge mphamvu zawo zonyamula kulemera kowonjezereka.
Slingshot khungu lotayirira
Mosiyana ndi anthu, nyama zokhala ndi ubweya nthawi zambiri zimakhala ndi khungu lotayirira, lomwe limawombera pamodzi ndi kugwedezeka kwamphamvu ndikufulumizitsa kuyenda kwa ubweya. Chifukwa chake, nyama nazonso zimauma mwachangu. Ngati minofu yapakhunguyo ikanakhala yolimba ngati mwa anthu, ikanakhalabe yonyowa, ofufuza akutero.
Kotero ngati galuyo amadzigwedeza yekha mwamphamvu atatha kusamba ndikutsanulira madzi pa chirichonse ndi aliyense wapafupi, ili si funso lamwano, koma kufunikira kwa chisinthiko.
