ʻO nā waiwai mechanical o nā mea e pili ana i nā ʻano mechanical o nā mea ma lalo o nā ʻano like ʻole (mahana, haʻahaʻa, waena), ma lalo o nā ukana waho like ʻole (tensile, compression, bending, torsion, impact, alternating stress, etc.).
ʻO ka hoʻāʻo ʻana o nā waiwai mechanical mea e pili ana i ka paʻakikī, ka ikaika a me ka elongation, ka paʻakikī o ka hopena, ka compression, ka shear, ka hoʻāʻo torsion a pēlā aku.
ʻO ka hoʻāʻo paʻakikī e pili ana i ka paʻakikī Brinell, ka paʻakikī Rockwell, ka paʻakikī Vickers, microhardness; ʻO ka hoʻāʻo ikaika ka ikaika hua a me ka ikaika tensile. Hoʻāʻo tensile e pili ana i nā kūlana:
Metala: GB/T 228-02, ASTM E 88-08, ISO 6892-2009, JIS Z 2241-98
ʻAʻohe metala: ASTMD 638-08, GB/T 1040-06, ISO 527-96, ASTMD 5034-09, ASTMD 638-08, GB/T 1040-06, ISO 527-96
ʻO nā lako hoʻāʻo i hoʻohana pinepine ʻia: ka mīkini hoʻāʻo honua mea, ka mīkini hoʻāʻo hopena, ka mīkini hoʻāʻo luhi, ka mea hoʻāʻo paʻakikī Whole Rockwell, ka mea hoʻāʻo paʻakikī Vickers, ka mea hoʻāʻo paʻakikī Brinell, a me ka mea hoʻāʻo paʻakikī Leeb.
ʻO ka hoʻāʻo ʻana i nā waiwai mīkini metala he mea nui ia no ka hoʻomohala ʻana a me ka hoʻomohala ʻana i nā mea metala hou, e hoʻomaikaʻi ana i ka maikaʻi o nā mea, e hoʻonui ana i ka hiki o ka mea (ke koho ʻana i ke kaumaha kūpono i ʻae ʻia), e nānā ana i ka hāʻule ʻana o nā ʻāpana metala, e hōʻoia ana i ka hoʻolālā kūpono o nā ʻāpana metala a me ka hoʻohana palekana a hilinaʻi hoʻi a me ka mālama ʻana i nā waiwai metala (e ʻike i ke ʻano o nā waiwai mīkini metala).
ʻO nā mea hoʻāʻo maʻamau: Paʻakikī (paʻakikī Brinell, paʻakikī Rockwell, paʻakikī Leeb, paʻakikī Vickers, a pēlā aku), ka tensile mahana lumi, ka tensile mahana kiʻekiʻe, ka tensile mahana haʻahaʻa, ke kūlou ʻana, ka hopena (ka hopena o ka mahana lumi, ka hopena o ka mahana haʻahaʻa, ka hopena o ka mahana kiʻekiʻe) luhi, kīʻaha, ka ukana huki a me ke kaha kiʻi, kīʻaha cone, reaming, compression, shear, torsion, flattening, a pēlā aku. Hoʻāʻo i nā waiwai mechanical Fastener a me ka papa welded (tube) nā waiwai mechanical (deformation, fracture, adhesion, creep, luhi), a pēlā aku.
