ʻO ka mīkini ka mea hana kūikawā no nā pono o ke kino transformer a me ka hana tilting o ka ʻāpana hana like. E māʻona ka mīkini i ke kūlana hana o ka ʻāpana hana kūpono i ka wā e hoʻohuli ai i nā kihi 90 a e hōʻoia i ka hana ʻole o ka ʻāpana hana i ka deformation a me nā kuʻi. I kēia manawa, hoʻokuʻu i ka ikaika o ka hana a hōʻoia i ka palekana.
