Te kaupapa hītori o te nekehanga whāriki

I te āhua tōmua o te peera nekehanga rārangi, i whakatakotoria he rarangi tokotoko rakau ki raro i te rarangi pereti reti. He rite tonu te kaupapa mahi a ngā peera nekehanga rārangi o ēnei rā, engari i ētahi wā ka whakamahia he pōro hei utu mō ngā roera. Ko te peera hurihuri māmā rawa ko te peera ringaringa rakau, he pūmau noa iho i waenganui i te wira me te toki. I muri mai ka whakakapia tēnei hoahoa e ngā peera hurihuri, i whakamahi i ngā roera porotaka maha hei whakakapi i te pūmau taketake, ā, ko ia wāhanga hurihuri he rite ki tētahi wira motuhake.

I kitea tētahi tauira tōmua o te whāriki pōro i runga i tētahi kaipuke Rōmana tawhito i hangaia i te tau 40 BC i te roto o Naimi, Itari: i whakamahia he whāriki pōro rakau hei tautoko i tētahi tēpu hurihuri. E kīia ana i whakaahua a Leonardo da Vinci i tētahi whāriki pōro i te tau 1500 pea. I roto i ngā āhuatanga rerekē o ngā whāriki pōro kāore i te tino pakari, ko tētahi mea tino nui ko te tukinga o ngā pōro, ka puta he waku anō. Engari ka taea te ārai i tēnei mā te whakanoho i ngā pōro ki roto i ngā whare iti. I te rautau 17, i whakaahua tuatahi a Galileo i te whāriki pōro o te "pōro whare herehere". I te mutunga o te rautau 17, i hoahoa, i hanga hoki e te Pākehā C. wallow ngā whāriki pōro, i tāutahia ki te waka mēra hei whakamātautau, ā, i whiwhi a P Worth o te Pākehā i te mana pateni mō te whāriki pōro. Ko te whāriki hurihuri mahi tuatahi me te whare herehere i hangaia e te kaihanga wati a John Harrison i te tau 1760 hei hanga i te wati H3. I te mutunga o te rautau 18, i whakaputa a HR hertz o Tiamana i tētahi pepa mō te ahotea whakapā o ngā whāriki pōro. I runga i ngā whakatutukitanga a Hertz, ko te r o Tiamana. He maha ngā whakamātautau kua mahia e Stribeck me Sweden's a Palmgren me ētahi atu, ā, kua whai wāhi ēnei ki te whanaketanga o te ariā hoahoa me te tatau i te roa o te ora o ngā peera hurihuri. Nō muri mai, ka whakamahia e NP Petrov o Rūhia te ture matotoru a Newton hei tatau i te waku o te peera. Ko te patent tuatahi mō te hongere poi i whiwhihia e Philip Vaughn o Camson i te tau 1794.

I te tau 1883, i whakaarohia e Friedrich Fisher te whakaaro mō te whakamahi i ngā mīhini whakaputa tika hei huri i ngā pōro maitai he rite te rahi me te porowhita tika, ā, koinei te pūtake o te umanga peera. I whakahaerehia e O Reynolds tētahi tātaritanga pāngarau o te kitenga a Thor, ā, i ahu mai i te whārite Reynolds, ā, koinei te pūtake o te ariā whakahinuhinu wai-ā-tinana.
