① Whakamātautau tensile: ine te ahotea me te rereke, whakatauhia te kaha (YS, TS) me te taupū kirihou (A, Z) o te rauemi
Te waahanga paipa tauira roa me te whakawhiti, pewa, tauira porohita (￠10,￠12.5)
He paipa rino taiapa angiangi te diameter, he paipa rino taiapa matotoru-rahi, me te tawhiti ine.
Nga korero: Ko te roa o te tauira i muri i te pakaru e pa ana ki te rahi o te tauira GB / T 1760
②Whakamātautau pānga: CVN, momo kakari C, momo V, mana J uara J/cm2
Tauira paerewa 10×10×55 (mm) Tauira kore-paerewa 5×10×55 (mm)
③Whakamātautau pakeke: Brinell pakeke HB, Rockwell pakeke HRC, Vickers pakeke HV, etc.
④Whakamātautau Hydraulic: te pehanga whakamatautau, te wa whakapumau pehanga, p=2Sδ/D
