TE WHAKAPĀWHITI I TE HIRIKOI DC ME TE FIUSE, KOIA TE TAPUTAPU TIROTIRO MATAATA

He tokomaha ngā tohunga hiko e whakaaro ana he tawhito ngā taputapu tiaki hiko, engari he taputapu tiaki matatau ngā kaiwawao hiko DC. He tika tēnei whakaaro?

Ka kitea ko te pihi whakarerekētanga āhuatanga wā-au o te fiusi he tata atu ki te pihi tātari āhuatanga o te kaha ako manawanui wera o te ara iahiko mahi tiakina, e tohu ana he pai ake te pānga tiaki taumaha, engari kāore tōna whakamahinga i te watea pērā i te kaiwawao ara iahiko DC. Mena ka pakaru te kaiwawao ara iahiko DC nā te nui o te au, ka taea te kati hei tuku hiko i muri i te rapurongoā, he tino māmā, he watea hoki. Me whakakapi te fiusi i te wā tika me te whakatakotoranga ōrite o te fiusi, me whakarato i ngā momo wāhanga e manawapa ana me ngā whakatakotoranga rerekē, he nui ngā raruraru ki te kaiwhakamahi.

Me aro nui atu hoki ki ngā waea fiusi. Hei tauira, me hono te pito waenga o te fiusi tīwiri ki te taha pūtake hiko, me te pito tīwiri ki te taha kawenga. Ki te kore, ka ngāwari te puta he aituā ru hiko ina whakakapia te fiusi.

Heoi, i tēnei wā, i roto i te hoahoa taiao o tō tātou whenua, ko ētahi o ngā umanga whakaputa wheketere, ngā whare tari me ētahi atu pūnaha tohatoha hiko e whakahaerehia ana e ngā tohunga aunoatanga hiko (ngā kaimahi BA4 me BA5, tirohia te Apitihanga C) e whakamahi ana i ngā whati ara iahiko DC. He iti noa iho e hiahia ana ki te whakamahi i ngā fiusi, engari i ētahi atu whenua whanaketanga ōhanga, ko te whakamahinga o ēnei momo taputapu hiko e rua he tata ki te haurua.

E mōhio ana tātou katoa, he tino teitei te utu o te pūwhakawhiti hiko DC mō te kaha nui o te raina matua, engari ko te fiusi me te iahiko whakatauranga he iti noa iho i te 30 ka taea te tapahi ngāwari i te iahiko poto o te 50 kiromita, ā, he iti noa te utu mō te whakakapi i te fiusi. Hei tāpiri, i muri i te whakaweto i te pūwhakawhiti hiko DC, ka noho tonu te kaha aukati o ngā hononga i muri i te whakakapinga ki tētahi mea tāpiri hou. I tēnei whakaaro, he pai ake te tapahi i te iahiko poto me te fiusi.

Hei tāpiritanga, ina ko te rerekētanga taumata iahiko o ia fiusi e ai ki te paerewa hua (arā, ko te iahiko kore-fiusi kua whakaaetia ko te 1.25in, ā, ko te iahiko fiusi kua whakaaetia ko te 1.6in) ko te 1.6 ngā wā, ka tohua e te paerewa hua ngā taumata katoa o ngā fiusi. Ka taea te whakamana i tōna whiriwhiringa ina whakamahia hei tiaki taumaha, engari he uaua ki te whakatutuki i ngā kaiwawao ara iahiko DC. Arā, he pai ake te whiriwhiringa o ngā fiusi i waenga i ngā taumata tiaki taumaha, ka taea te whakaiti i te mata o te rahunga hiko i te wā e mahi tiaki taumaha ana.
