I'a le pito i lalosooga fetuutuunaita'amilosagae masani ona faʻaaogaina e faʻafefe ai le vibration ma le pisapisao o le pamu i totonu ma fafo o le pamu. Matou te taʻua i latou o pamu sootaga.

Aemaise lava, ua vaevaeina a tatou oloa i soʻotaga faʻalavelave faʻafuaseʻi ituaiga ma faʻapipiʻi upega faʻapipiʻi, ma faʻapipiʻi ituaiga uʻamea e vaevaeina i le ituaiga uʻamea ma le tuʻufaʻatasia ituaiga faʻapipiʻi. O lenei ituaiga o paipa fa'amama e mafai ona fa'aitiitia le tau.

Faʻalauteleina soʻotaga ua vaevaeina i soʻotaga faʻalautele axial ma soʻotaga faʻalauteleina lateral. Faʻapipiʻi faʻalautele faʻapipiʻi e masani ona faʻaaogaina e faʻafefe ai le faʻalauteleina ma le faʻapipiʻiina o paipa i le itu faalava.

E masani lava ina ia mautinoa le saogalemu o le faʻaogaina o le paipa, o loʻo i ai galuega tauave nei: taui ma faʻafefe le axial, lateral ma angular thermal deformation o le paipa; faʻafefeteina o meafaigaluega ma faʻaitiitia le aʻafiaga o le faʻaogaina o meafaigaluega i luga o le paipa; mitiia le deformation o le paipa e mafua mai mafui'e ma le eleele.
