Ngā hangarau matua mō ngā peera karetao ahumahi

 

Hei tētahi o ngā taputapu matua o ngā karetao ahumahi, e rua ngā momo peera o ngā karetao ahumahi, ko tētahi ko tepeera angiangi-wāhanga ōrite,ā, ko tētahi atu ko tepeera roera porotaka whakawhitiHei tāpiritanga, kei reira ngā peera whakaiti harmonic, ngā peera raina, ngā peera porowhita, me ētahi atu, engari ko ngā momo peera tuatahi e rua ka whakamahia nuitia.

 

Ngā hangarau matua mō ngā peera karetao ahumahi

 

Ko te whanaketanga o ngā karetao ahumahi hou he māmā noa iho, ā, me tāuta ngā peera ki tētahi wāhi iti, me iti hoki te rahi, me māmā hoki te taumaha, arā, he māmā. Engari i te wa ano, ko te mahi o te kawenga teitei, te tika o te hurihuri, te pumau o te oma, te tere tūnga teitei, te tika o te whakahokinga, te roa o te ora me te pono teitei o te karetao me whai kaha teitei o te peera karetao tautoko, he tino tika, he pakari teitei, he iti te taipana waku, he roa te ora me te pono teitei.

 

1. Ngā peera angiangi o te wāhanga whakawhiti ōrite

 

He rerekē ngā peera porowhita-rite angiangi i ngā peera porowhita-rite noa, ā, ko te nuinga o te wāhanga whakawhiti o ngā peera porowhita-rite he tapawhā i ia raupapa, ā, kua hangaia ngā ine kia pumau. I roto i te raupapa kotahi, kāore te rahi o te wāhanga whakawhiti e rerekē ana, ā, kāore e piki ake me te pikinga o te rahi o te diameter o roto, nō reira ka kiia he peera porowhita-rite te wāhanga angiangi. Kei roto i ngā peera porowhita-rite te raupapa peera porowhita-rite he porowhita-whā-ira angiangi, he porowhita-whā-ira te raupapa peera porowhita-koki angiangi me te raupapa peera porowhita-hohonu angiangi, e whakamahia ana i te hope, te tuke, te ringaringa me ētahi atu wāhanga o ngā karetao ahumahi e hiahia ana ki te rahi wāhanga-iti me ngā here. Mēnā he rite te rahi o te diameter o roto, he nui ake te maha o ngā porowhita maitai i roto i ngā peera porowhita-rite angiangi i ērā o ngā peera hurihuri paerewa, nō reira ka pai ake te tohatoha kaha o roto o te peera, ka whakaitihia te whakarerekētanga ngāwari o te hononga i waenga i te porowhita maitai me te awaawa, ā, ka pai ake te kaha o te peera.

 

2. Ngā peera roera angiangi-paki

 

Ko te hanganga o roto o ngā peera roera porotaka angiangi-whakawhiti, ka whakamahia te whakatakotoranga poutū o ngā roera ki te 90°, ā, ka taea e te peera kotahi te tu atu i te mahi tahi o te kaha radial, te kaha axial rua-ara me te nekehanga hurihuri i te wā kotahi, ā, he mea whakarite ki ngā roera he ārai mokowā, he poraka wehe rānei, ka taea te ārai i te piko o ngā roera, te huri tahi rānei i waenga i ngā roera, ā, ka ārai pai i te pikinga o te taipana waku. Hei tāpiri, ko te hanganga o te whakaritenga whakawhiti poutū o ngā roera ka taea te karo i te āhuatanga raka o ngā roera; I te wā kotahi, nā te mea kua wehea ngā mowhiti o roto me waho o te peera, ka taea te whakarite i te ātea, ā, ka taea te whiwhi i te tika o te hurihuri teitei ahakoa te pēhanga. He whānuitia te whakamahinga o ngā peera roera whakawhiti i roto i te hurihuri hope o ngā karetao ahumahi, pakihiwi, ringa, ringaringa me ētahi atu wāhanga hurihuri o ngā karetao ahumahi nā te mea he hanganga māmā, he tika te hurihuri, he pakari pai, he taipana waku pumau, me ētahi atu.
