He hoihoi loa ka ʻōlelo Pākē. Hiki i ka huaʻōlelo like ke loaʻa nā hopena like ʻole ke hoʻohana ʻia i nā kūlana like ʻole. No ka laʻana, ʻo ka huaʻōlelo "shui bao" ʻo ia hoʻi ke kuleana ʻole a haʻalele i nā poʻe ʻē aʻe. Hiki ke hoʻonui ʻia i ka manaʻo he paio a haʻihaʻi kekahi ma muli o ke kuʻikahi.

ʻO ka hoʻolei ʻana i ka ʻeke he wehewehe hewa no nā kaʻa rotor hōʻeha, e pili ana i ka hopena o ka radial waho deformation o ka hopena wili rotor ma muli o ka wikiwiki. Inā ʻike mākou i kekahi mea e pili ana i nā motika rotor hōʻeha, hiki iā mākou ke ʻike aia kekahi mau palena i ka wikiwiki o kēia ʻano kaʻa.

ʻO ke kumu nui o ka hoʻolei ʻana i ka pūʻolo ka hopena centrifugal
ʻO kahi mea e neʻe pōʻai ai, ma muli o kona inertia ponoʻī, e lele mau ana ma ka ʻaoʻao tangent o ka pōʻai. Ke nalo koke ka ikaika o waho a i ʻole lawa ʻole e hāʻawi i ka ikaika centripetal e pono ai no ka neʻe pōʻai, e neʻe mālie ia mai ke kikowaena o ka pōʻai. Kapa ʻia kēia hanana centrifugal phenomenon.
I ka wā o ka hana ʻana o ke kaʻa, neʻe kēlā me kēia ʻāpana o ka ʻāpana rotor i ka neʻe pōʻai puni i ke kikowaena o ke kumu kaʻa. E like me ka pilina ma waena o ka wikiwiki a me ka ikaika centrifugal i ka neʻe pōʻai, ʻoi aku ka nui o ka wikiwiki, ʻoi aku ka nui o ka ikaika centrifugal.
ʻO ka mea maʻamau i ʻike ʻia i loko o ke ola, ʻo ia ka mīkini holoi holoi wai, ka pulupulu lole, a pēlā aku. ʻO nā haʻuki, a me nā mea ʻē aʻe, he mau hoʻohana pono ia o ke kumu centrifugal.
Loaʻa i nā mea a pau kona pono a me nā pōʻino. Ma muli o ka ikaika centrifugal, hiki mai kekahi mau pōʻino, e pōʻino ai ke ola o nā kānaka. No nā kaʻa e holo ana ma nā alanui ākea, hāʻawi ʻia ka ikaika centripetal e pono ai no ka huli ʻana e ka friction static ma waena o nā huila a me ka ʻili o ke alanui. Inā kiʻekiʻe ka wikiwiki i ka wā e huli ai, ʻoi aku ka nui o ka ikaika centripetal F ma mua o ka friction static kiʻekiʻe, a e hana ke kaʻa i ka neʻe centrifugal a hoʻokau i nā ulia kaʻa. No laila, ʻaʻole ʻae ʻia nā kaʻa e ʻoi aku ma mua o ka wikiwiki i kuhikuhi ʻia ma nā piko o ke alanui. ʻO nā huila wili wili kiʻekiʻe, nā huila lele, a pēlā aku.

He aha ka ikaika centrifugal?
ʻO ka ikaika Centrifugal kahi ikaika maʻemaʻe, kahi hōʻike o ka inertia, kahi e hoʻoneʻe ai i ka mea kaʻa mai kona kikowaena o ka ʻōwili. Ma Newtonian mechanics, ua hoʻohana ʻia ka ikaika centrifugal e hōʻike i ʻelua manaʻo like ʻole: kahi ikaika inertial i ʻike ʻia i loko o kahi kiʻi kuhikuhi non-inertial, a me ke koena o ka ikaika centripetal. Ma nā mechanics Lagrangian, hoʻohana ʻia ka ikaika centrifugal i kekahi manawa e wehewehe i nā pūʻali ākea ma lalo o kahi ʻōnaehana hoʻonohonoho laulā.
I ka pōʻaiapili maʻamau, ʻaʻole ikaika maoli ka ikaika centrifugal. ʻO kāna hana wale nō e hōʻoia i hiki ke hoʻohana ʻia nā kānāwai o ka neʻe ʻana o Newton i kahi kiʻi kuhikuhi. ʻAʻohe ikaika centrifugal i loko o kahi pahu kuhikuhi inertial, a pono wale ka ikaika inertial i loko o kahi pahu kuhikuhi non-inertial.
E noʻonoʻo ʻoe i kahi disk e kaʻapuni ana a puni kona kikowaena me ka wikiwiki angular o ω. Aia ma ka diski he poloka lāʻau o ka m, i hoʻopili ʻia e ke kaula, ʻo ka hopena ʻē aʻe i hoʻopaʻa ʻia i ke kikowaena o ka disk (ʻo ia hoʻi ke kikowaena o ka rotation). ʻO ka lōʻihi o ke kaula he r. Holoi ka poloka lāʻau me ka diski. Ke manaʻo nei ʻaʻole ʻaʻohe paʻakikī, ʻolokaʻi ka poloka lāʻau ma muli o ke ʻano o ke kaula. No ka mea nana e huli ana me ka diski, pa'a ka poloka laau. Wahi a ke kānāwai o Newton, ʻo ka ʻupena ʻupena ma ka poloka lāʻau he ʻole. Eia naʻe, hoʻokahi wale nō ka ikaika o ka poloka lāʻau, ʻo ka ʻūhā o ke kaula, no laila ʻaʻole ʻole ka ikaika ʻupena. Ua kue anei keia i ke kanawai o Newton? Pono wale ke kānāwai o Newton i loko o kahi ʻōnaehana inertial, akā ʻo ka ʻōnaehana kuhikuhi o ka mea nānā e hoʻololi ana me ka disk he ʻōnaehana non-inertial, no laila ʻaʻole paʻa ke kānāwai o Newton ma aneʻi. I mea e paʻa mau ai ke kānāwai o Newton i loko o kahi ʻōnaehana non-inertial, pono e helu ʻia kahi ikaika inertial, ʻo ia hoʻi ka ikaika centrifugal.
ʻO ka nui o ka ikaika centrifugal ua like ia me ka hoʻopaʻapaʻa i hāʻawi ʻia e ke kaula, akā ʻo ke kuhikuhi. Ma hope o ka hoʻokomoʻiaʻana o ka ikaika centrifugal, mai ka manaʻo o kahi mea nānā e hoʻololi ana me ka diski, ua hoʻokauʻia ka'āpana lāʻau i ka manawa hoʻokahi i ka manaʻo o ke kaula a me ka ikaika centrifugal, i like ka nui a me ke kū'ē i ke kuhikuhi, a me ka upena. ʻo ka ikaika he zero. I kēia manawa, paʻa ka poloka lāʻau, a paʻa ke kānāwai o Newton.
