ʻO ke kuʻekuʻe, ka manawa, a i ʻole ka manawa o ka ikaika (e ʻike i nā huaʻōlelo ma lalo) ke ʻano o ka ikaika e hoʻohuli i kahi mea e pili ana i kahi axis, fulcrum, a i ʻole pivot.
Ana ia i ka nui o ka ikaika o ka mea hana e hiki ai ke hoololi, e like me ka hoʻoheheʻe hopena a i ʻole nā mea hana ʻē aʻe. Me ka lawa ʻole o ka torque, ʻaʻole hiki ke hana me ka mea hana i kekahi mau hana e koi ai i ka ikaika.
E like me ka ikaika o ka pana a huki paha, hiki ke manaʻo ʻia he wili i kahi mea.
Ma ka makemakika, ua wehewehe ʻia ka torque e like me ka hua kea o ka lever-arm distance vector a me ka vector ikaika, ka mea e manaʻo ai e hana i ka rotation.
ʻO ka torque e ana i ka ikaika huli ma luna o kekahi mea e like me ka bolt a i ʻole ka huila lele.
No ka laʻana, ʻo ka hoʻokuʻu ʻana a i ʻole ka huki ʻana i ka ʻau o kahi wīwī i hoʻopili ʻia i ka nati a i ʻole ka pahu e hoʻohua ai i kahi torque (ka hoʻohuli ʻana) e wehe a hoʻopaʻa i ka nati a i ʻole ka pahu.
ʻO ka hōʻailona no ka torque ka mea maʻamau ka leka Helene tau. Ke kapa ʻia ʻo ia ka manawa o ka ikaika, ua kapa ʻia ʻo M.
ʻO ka nui o ka torque e pili ana i ʻekolu mau nui: ʻo ka ikaika i hoʻohana ʻia, ka lōʻihi o ka lima lever e hoʻopili ana i ke axis i kahi o ka noi ikaika, a me ke kihi ma waena o ka vector ikaika a me ka lima lever.
ʻO R ka neʻe hoʻoneʻe (he vector mai ka lae kahi i ana ʻia ai ke koʻikoʻi (maʻamau ke koʻi o ka hoʻololi ʻana) a i kahi i hoʻohana ʻia ai ka ikaika), ʻo F ka vector ikaika, × hōʻike i ka hua kea, θ ka huina ma waena o ka kaha kaha a me ka lima lever vector.
He mea nui ka lōʻihi o ka lima lever; ʻO ke koho ʻana i kēia lōʻihi ma hope o ka hana ʻana o nā levers, pulleys, gears, a me nā mīkini maʻalahi ʻē aʻe e pili ana i ka pono mechanical.
ʻO ka ʻāpana SI no ka torque ka mika newton (N⋅m). No nā mea hou aku e pili ana i nā ʻāpana o ka torque, e ʻike i nā Units.
ʻO wau ʻo Joost Nusselder, ka mea nāna i hoʻokumu i ke Kauka Mea Hana, mea kūʻai maʻiʻo, a me ka makuakāne. Makemake au i ka hoʻāʻo ʻana i nā mea hana hou, a me kaʻu hui ua hana au i nā ʻatikala blog hohonu mai ka makahiki 2016 e kōkua i ka poʻe heluhelu kūpaʻa me nā mea hana a me nā ʻōlelo aʻoaʻo.
