Pono kahi mōlina paikikala maikaʻi e hoʻokō i nā kūlana ʻekolu o ke kaumaha māmā, ka ikaika lawa a me ke kūpaʻa kiʻekiʻe. Ma ke ʻano he haʻuki paikikala, ʻo ke mōlina ke kaumaha
ʻOi aku ka maikaʻi o ka māmā, ʻoi aku ka liʻiliʻi o ka hoʻoikaika e pono ai a ʻoi aku ka wikiwiki o kou holo ʻana:
ʻO ka ikaika lawa ʻo ia hoʻi ʻaʻole e haki a kūlou ke kiʻikuhi ma lalo o ka holo ikaika kiʻekiʻe;
ʻO ke kūpaʻa kiʻekiʻe e pili ana i ke kūpaʻa o ka mōlina. I kekahi manawa ʻaʻole paha he hopohopo palekana ko kahi mōlina me ka paʻa ʻole, akā hoʻoili ʻia ka ikaika o ka mōlina i ka wā e holo ana.
ʻO ka ʻokoʻa o ke alakaʻi e hoʻomaopopo ai ka mea holo e like me ke kauō ʻana o ke paikikala i ka wā e hehi ai ma luna. ʻOiai inā ua lawa ka māmā a me ka ikaika o ke kino, akā ʻaʻole maikaʻi ka paʻakikī, hoʻokahi mea nō ia.
He paikikala haʻuki haʻahaʻa. Ma waena o nā ʻano kaʻa ma ka mākeke, ʻo nā mea hana mōlina e hiki ke hoʻokō i nā kūlana mōlina maikaʻi i ʻōlelo ʻia ma luna nei: alumini metala,
ʻEhā ʻano o ke kalapona fiber, ka titanium alloy a me ke kila alloy.

1. Mea kila kila:
ʻO ke kila ka mea hana kuʻuna loa no nā paikikala. Hiki ke hoʻohana ʻia nā ʻano kila hao like ʻole o kēia au i ka paʻakikī, ka elasticity, ka hoʻoili ʻana a me ke kūpaʻa.
Loaʻa nā hopena maikaʻi. ʻO ka hemahema wale nō, ʻo ke kaumaha t o ke kila he kīnā, a ʻoi aku ke kaumaha ma mua o ka helu t o nā mea. -Ma ke ʻano laulā, ʻo ke kila metala
He haʻahaʻa ke kumukūʻai o nā mea hana. Eia nō naʻe, ʻaʻole haʻahaʻa ke kumukūʻai maikaʻi o ke kiʻikuhi kila i hana ʻia me ke kila a me ke kila molybdenum.
Hiki ke hoʻohālikelike ʻia nā mea.

2. Mea hoʻohuihui alumini:
He ʻano naʻaupō ke ʻano o ka alumini metala, he māmā, he māmā, a he paʻa loa, akā i ka manawa like, hōʻike pū ia i ka pane haʻalulu o kēlā me kēia kiko J ma ka honua.
Ua hoʻohāʻawi iki ʻia ka ʻoluʻolu. He ʻano haʻahaʻa ke kumu kūʻai a he nui nā ʻano o ke kiʻikuhi, he ʻano ia e kūpono i nā mea a pau ke kūʻai.

3. ʻO ke kalapona kalapona:
ʻO nā ʻano o ke kaula kalapona: elasticity, ka manaʻo holo paʻa, ka hoʻomau ʻana o ka holo moana mamao, a me ka ʻoluʻolu kiʻekiʻe. ʻO ka hemahema, he kiʻekiʻe loa ke kumukūʻai, a ʻo wau
ʻO ke ola lawelawe maʻamau (i helu ʻia mai ka hale hana) he 5 a 6 mau makahiki wale nō. ʻOiai inā ʻaʻohe puʻupuʻu i loko o ke kiʻikuhi i loko o 6 mau makahiki, ʻo kona ʻano kemika nō naʻe
Ua palaho ʻia ʻo E, a ʻaʻole ʻōlelo ʻia no ka poʻe holo lio e hoʻomau i ka hoʻohana ʻana.

4. ʻO ke kinikini titanium:
Ua like loa nā ʻano o ka titanium alloy me ka hui pū ʻana o ka alumini alloy a me ke kalapona fiber. Hiki iā ia ke loaʻa ka elasticity e like me ke kalapona fiber a hiki ke hauʻoli i ka alumini alloy.
ʻO kona māmā a me kona paʻakikī. ʻO kona kiko kūikawā ma muli o ka lele ʻana o ke koina hoʻonui, ka mea e hiki ʻole ai ke pena ma luna o ka ʻili metala, akā ʻo ka mea pōmaikaʻi, ʻo ka titanium alloy
ʻAʻole maʻalahi ka pala a me ka oxidize, a he ʻokoʻa nō hoʻi ke kala. Akā, ʻaʻole like kona kumukūʻai me nā mea mua ʻekolu.
