O mea ta'itasi ta'itasi e fa'aogaina sa'o machining e ausia ai le geometry nifo mana'omia, fa'amautinoaina lelei ma lelei le felauaiga o le mana. Faatasi ai ma le faʻaeteete i faʻamatalaga, o mea faʻapipiʻi taamilomilo na gaosia e faʻaalia ai le malosi, tumau, ma le faʻatinoga.
Faatasi ai ma le tomai i le faʻaogaina o mea faʻapipiʻi pipiʻi, e mafai ona matou faʻafetaui manaoga faʻainisinia faʻaonaponei, tuʻuina atu fofo e sili ona lelei i le faʻatinoga, faʻatuatuaina, ma le umi o le ola.
