Me pēhea te whakarerekētanga o te ahunga nekehanga e te mekameka taraiwa?

Mā te tāpiri i tētahi wira waenga ka whakamahia te mowhiti o waho hei whakatutuki i te tuku hei whakarerekē i te ahunga.

Ko te hurihanga o te taputapu he mea hei akiaki i te hurihanga o tētahi atu taputapu, ā, hei akiaki i te hurihanga o tētahi atu taputapu, me hono ngā taputapu e rua tetahi ki tetahi. Nō reira, ko tāu e kite nei i konei, ina huri tetahi taputapu ki tētahi taha, ka huri tetahi atu taputapu ki te taha kē, ka huri te ahunga o te kaha. Ina huri te mekameka, ina eke pahikara koe, ka kitea ngāwari e koe ko te ahunga hurihanga o te taputapu he rite ki te ahunga o te mekameka, ā, he rite tonu te ahunga hurihanga o te taputapu iti me te taputapu nui, nō reira kaua e huri te ahunga o te kaha.

Ko ngā taputapu he tuku miihini e whakamahi ana i ngā niho o ngā taputapu e rua hei hono tetahi ki tetahi hei tuku i te mana me te nekehanga. E ai ki ngā tūranga whanaunga o ngā tuaka taputapu, ka wehea ēnei ki te tuku taputapu porotaka tuaka whakarara, te tuku taputapu piko tuaka whakawhiti me te tuku taputapu porowhita tuaka whakarara hei huri i te ahunga.

He tere te tuku taputapu i te nuinga o te wā. Hei whakapai ake i te pumau o te tuku me te whakaiti i te wiri pānga, he pai ake te maha o ngā niho. Ko te maha o ngā niho o te pinion ka taea te z1=20~40. I roto i te tuku taputapu tuwhera (haurua-tuwhera), nā te mea ko te nuinga o ngā niho taputapu he pakaru me te pakaru, kia kore ai e iti rawa te taputapu, kaua e nui rawa ngā niho o te taputapu pinion. I te nuinga o te wā, ko te z1=17~20 te mea e taunakihia ana.

I te pūwāhi pātata P o ngā porowhita nekehanga taputapu e rua, ko te koki koi i hangaia e te paerewa noa o ngā pihi kōtaha niho e rua (arā, te ahunga kaha o te kōtaha niho) me te pātata noa o ngā porowhita nekehanga e rua (arā, te ahunga nekehanga inamata i te pūwāhi P) ka kiia ko te koki pēhanga, e kiia ana hoki ko te koki mata. Mō te taputapu kotahi, ko te koki kōtaha niho. Ko te koki pēhanga o ngā taputapu paerewa he 20″ te nuinga. I ētahi wā, ka whakamahia hoki te α=14.5°, 15°, 22.50° me te 25°.
