He aha i te nuinga o te wā he mīhini kei muri i ngā motuka hākinakina?
E rua ngā momo miihini motuka kei muri: te miihini o muri (e kiia nei i konei ko te miihini o muri) me te miihini o muri.
Ko te mīhini waenga, i tapaina nā te mea kei waenganui i ngā toki o mua me muri o te motuka te mīhini, koinei te kōwhiringa tuatahi o te nuinga o ngā motuka tere. E ai ki te momo taraiwa, ka wehea ki te puku waenga o muri me te puku waenga o ngā wira katoa:
Ko te tikanga o te taraiwa-waenga-wira he taraiwa-waenga-wira me te taraiwa-whā-wira kei roto i te mīhini. Pērā i te taraiwa-waenga-muri, ka whakamahia tēnei tauira i roto i ngā motuka hākinakina me ngā motuka nui ake te mahi. Engari ki te whakatauritea ki te taraiwa-waenga-muri, he nui ake ngā rohe whakahaere me te huripokitanga o te taraiwa-katoa-wira. Mai i te whakamahinga o te miihini-waenga, me pēnei pea nā te mea he nui ngā painga o tēnei āhua. Nā te mea he nui rawa te taumaha o te mīhini, nō reira ka taea e te mīhini waenga te whiwhi i te tohatoha kawenga toki pai rawa atu, he pai ake te pumau o te whakahaere me te whakamarie o te ekenga. Ā, he tata te mīhini ki te transaxle, kāore he toki taraiwa, kia whakaitihia ai te taumaha o te motuka, me te pai ake o te tuku. Hei tāpiri, he kukū te taumaha o te tauira mīhini waenga, ā, he iti te taipana inertia o te tinana i te ahunga o te piu papatahi. I te hurihanga, he tairongo te wira urungi, ā, he pai te nekehanga. He mārama ngā ngoikoretanga. He nui te wāhi e nohoia ana e te whakaritenga mīhini i roto i te motuka me te pūtu, ā, e rua, e toru rānei ngā nohoanga ka taea te uru ki roto i te motuka. Ā, kei muri i te taraiwa te mīhini, he tino tata te tawhiti, he ngoikore te ārai oro me te pānga ārai o te wāhanga, ā, kua heke te whakamarie o te ekenga. Engari ko te hunga e hoko ana i ngā waka tere, kāore e aro nui. Ko tētahi atu ko te mīhini o muri, arā, kua whakaritea te mīhini i muri i te toki o muri, ko te mea tino tohu ko te pahi, ka taea te tatau i te mīhini o muri o te motuka pāhihi.
