He lōʻihi ka lōʻihi o nā ʻāpana pōʻai a loaʻa ka hana ʻoki maikaʻi, akā aia kekahi ʻano o ka ʻaʻahu ma hope o ka lōʻihi o ka hoʻohana ʻana, a pili kēia ʻaʻahu i nā kumu nui.

1.Materials

ʻOi aku ka maikaʻi o ke kūpaʻa paʻa o ka mea i hoʻohana ʻia no ka hana ʻana i ka maka pōʻai, akā i ka manawa like ʻoi aku ka paʻakikī. He kū'ē ka paʻakikī a me ka paʻakikī, ʻo ia hoʻi kahi ʻano pono e hoʻomaikaʻi ʻia. Inā he graphite poepoe maka, hiki ke koho i ka mea me ka oi aku ka oolea.

2.ka uhi uhi

Loaʻa nā pono o ka paʻakiki kiʻekiʻe, ke kūpaʻa ʻana o ka ʻaʻahu maikaʻi, a me ka coefficient friction haʻahaʻa, a ʻo ia ke ʻano hana hana kūpono i kēia manawa. Eia naʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana, a ʻaʻole lawa ka ʻenehana kūloko o kēia manawa ma kēia wahi. Hoʻohana nui ʻia nā ʻāpana poʻe i uhi ʻia i ka graphite a pono.

No laila, inā makemake ʻoe e hōʻemi i ka ʻaʻahu ʻana o ka maka pōʻai, hiki iā ʻoe ke hāʻawi i ka mea nui i ka mea a me ka uhi.
