Ko ngā arawhata, ngā ararewa hikoi aunoa rānei, ngā arawhata, me ngā arawhata he huarahi kawe tangata e kawe ana i ngā kaihaerere i roto i te āhua o ngā whitiki kawe. I te nuinga o te wā, ko ngā arawhata e pā ana ki ngā arawhata. Ko ngā toa hokohoko te mea tino noa, nō reira, he aha te rahi o te arawhata? ? He aha ngā tawhā matua o te arawhata?
He aha te rahi whānui o te arawhata?
E rua ngā momo o ngā arawhata: ko te koki 30-tohu me te koki 35-tohu. He mea noa ināianei te tāuta i tētahi arawhata me te whānui o ngā taahiraa kotahi mita. Ko te whānui o waho o te arawhata he 1.55 mita. Ka taea te tāuta mita) Mēnā he nui ake i te 1.6 mita te whānui o tētahi waeine kotahi, ko te tātaitanga mō te whānuitanga o te arawhata ko te mua o te arawhata me te tuara o te arawhata me te rahi waenga (ki te kimi i te rahi waenga o te arawhata, whakamahia te mahi pākoki tan30∠=0.577 me te tan35∠=0.700. ) i runga i te arawhata me te teitei hiki o te 4 mita me te koki o te 35 nekehanga hei tatau i te pito o mua me te pito o muri he tata ki te 4.8 mita (he rerekē te rahi o ia kaihanga arawhata engari kāore i te nui te rerekētanga rahi) me te (4.0/0.7=5.71)=11.4 mita. Nō reira, ko te whānui o ngā arawhata e rua e 4-mita te roa he 3.6 mita, ā, ko te whānui he 11.4 mita.
Kāore te arawhata e hangai ana ki te roa, engari e whakawhirinaki ana ki te teitei o te papa. Ko te teitei o te papa tuatahi o te toa hokohoko rahi-waenga ko te 5.4m, ā, ko te teitei i runga ake i te papa tuarua ko te 4.5m. He tino utu nui ngā toa hokohoko, nō reira, ko te iti ake o te horahanga o te arawhata, ko te pai ake. I tēnei wā, ko te nuinga o rātou e whakamahi ana i te whakatakotoranga o te 35°-100.
Ngā tawhā matua o te arawhata:
1. Teitei o te hiki: ko te tikanga kei roto i te 10 mita, i ētahi wā motuhake ka tae ki ngā tekau mita.
2. Koki piko: ko te tikanga he 30°, 35°.
3. Whānui o ngā kaupae: 600mm, 800mm, 1000mm.
4. Tere: ko te tikanga he 0.5 m/s, ā, ko ētahi trapezoid ka eke ki te 0.65 m/s, 0.75 m/s
5. Te kaha kawe ā-arotake: i tatauhia i runga i te tere o te 0.5 m/s, ko te kaha kawe o ngā whānui takahanga rerekē he 4500 tāngata/haora, 6750 tāngata/haora me te 9000 tāngata/haora.
6. Teitei haumaru i runga ake i ngā arawhata me ngā pēra: i runga ake i ngā arawhata o te arawhata, me whai teitei poutū mārama kia kaua e iti iho i te 2.3m. Me rite te teitei kupenga ki te nekehanga katoa o ngā arawhata me ngā pēra kia pai ai te haere haumaru me te kore e araia o ngā pāhihi i runga i te arawhata.
7. Te tawhiti haumaru i waenganui i te taha o waho o te reera ringaringa me te whare, te arai rānei: kaua te tawhiti whakapae i waenganui i te rārangi pokapū o te reera ringaringa me te pakitara whare, arai rānei e tata ana, e iti iho i te 500mm ahakoa pēhea, ā, me pupuri te tawhiti kia 2.1m te teitei i runga ake i ngā kaupae o te arawhata.
Ka taea te whakaiti i tēnei teitei o te 2.1m mēnā ka tangohia ngā mahi tika hei karo i te tūponotanga o te whara.
Ko ngā kōrero o runga ake nei he whakataki mātauranga mō te rahi whānui o te arawhata me ngā tawhā matua o te arawhata. Ki taku whakaaro ka nui ake tō māramatanga i muri i te pānui. Hei tohutoro noa iho tēnei, ā, ko taku tumanako ka whai hua ki a koe.
