He aha te mekameka taraiwa? Ko te mekameka taraiwa he tikanga tuku e tuku ana i te nekehanga me te mana o te pīkau taraiwa me te āhua niho motuhake ki te pīkau taraiwa me te āhua niho motuhake mā roto i te mekameka.
He kaha te kawenga o te mekameka taraiwa (he nui te kaha e whakaaetia ana) ā, he pai mō te tuku i waenga i ngā pou whakarara i ngā tawhiti roa (e hia mita). Ka taea te mahi i roto i ngā taiao uaua pēnei i te pāmahana teitei, te parahanga hinu rānei. He iti te tika o te hanga me te tāutanga, ā, he iti hoki te utu. Heoi, kāore te tere tere me te ōwehenga tuku o te mekameka taraiwa i te pumau, nō reira he iti ake te pumau o te tuku, ā, he pānga me te haruru. Ko te nuinga o te wā e whakamahia ana i roto i te keri maina, te ahuwhenua, te hinu, te motopaika/pahikara me ētahi atu ahumahi me ngā mīhini, me te maha o ngā taputapu, ngā taputapu kāinga, me ngā ahumahi hiko. Ka whakamahia hoki e te raina whakaputa ngā mekameka tere-rua hei kawe i ngā taputapu.
Ko te mekameka tere rua e kiia nei he mekameka roera. Kāore te tere neke V0 o te mekameka e rerekē. Ko te tere o te roera i te nuinga o te wā = (2-3) V0.
Kāore i te maha ngā taputapu aunoa noa e whakamahi ana i ngā puku mekameka, nā te mea kāore i te teitei ngā whakaritenga mō te kaha kawenga i raro i ngā tikanga mahi whānui, ā, he nui ake te aro ki te tere teitei, te tino tika, te iti o te tiaki, te iti o te haruru, me ētahi atu. Koinei ngā ngoikoretanga o ngā puku mekameka. I te nuinga o te wā, ko te rakau hiko o te hoahoa mīhini o mua e akiaki ana i ngā taputapu o ngā mīhini maha mā te tuku mekameka. Ko tēnei tauira mīhini taputapu "kotahi tuaka, maha nekehanga" te āhua nei he ihirangi hangarau, engari kāore i te rongonui i nāianei (ngāwari ngoikore, te whakarerekētanga uaua, ngā whakaritenga hoahoa teitei), nā te mea he maha ngā tono i roto i te umanga he taputapu hau te nuinga, ā, he maha ngā mīhini he mana motuhake (rango) katoa, ā, ka taea te whakahaere ngāwari i ngā nekehanga mā te hōtaka.
He aha te hanganga o te mekameka taraiwa?
Ko te mekameka taraiwa he tikanga tuku e tukuna ai te mana e te mekameka mā te hononga o ngā roera me ngā niho o te porotiti. Ko ngā wāhanga e uru ana ki te mekameka taraiwa ko ngā porotiti, ngā mekameka, ngā mea whakangāwari me ngā taputapu e pā ana (pēnei i ngā whakatikatika kume, ngā kaiārahi mekameka), ka taea te whakataurite me te whakamahi kia rite ki te āhuatanga tūturu. I roto i ēnei, ko te mekameka he mea tito mai i ngā roera, ngā pereti o roto, o waho hoki, ngā pū, ngā pine me ētahi atu wāhanga.
Kāore e taea te wareware i ngā tawhā nui o te mekameka taraiwa.
1. Te Pitch. Ko te tawhiti i waenganui i ngā pokapū o ngā roera e rua e tata ana i runga i te mekameka roera. Ko te nui ake o te pitch, ko te nui ake o te rahi o ngā wāhanga, ka taea te tuku mana nui ake me te pikau kawenga nui ake (mō te tuku mekameka roera tere-iti me te kawenga-taumaha, me whiriwhiri te pitch nui). I te nuinga o te wā, me whiriwhiri koe i tētahi mekameka he iti rawa te pitch e whai ana i te kaha tuku e hiahiatia ana (ki te kore e ranea te kaha o te mekameka rarangi kotahi, ka taea e koe te whiriwhiri i tētahi mekameka rarangi maha) kia iti ai te haruru me te pumau.
2. Ōwehenga tuku tere. Ko te ōwehenga tuku tere o te mekameka taraiwa ko i=w1/w2, ko w1 me w2 ngā tere hurihuri o te pīkau taraiwa me te pīkau taraiwa. Me tutuki i a i ētahi tikanga (he ōrite te maha o ngā niho o ngā pīkau e rua, ā, ko te roa o te taha piripono he rite tonu ki te tauoti o ngā wā piko), he pūmau.
3. Te maha o ngā niho pinion. Mā te whakanui tika i te maha o ngā niho pinion ka taea te whakaiti i te kore taurite o te nekehanga me ngā kawenga hihiri.
