Mphamvu zokolola ndi lingaliro lofunikira m'munda wamakina opanda chitoliro.Ndiko kupsinjika kwa chitoliro chachitsulo chosasunthika pamene zinthu za ductile zimatulutsa.Pamene chitoliro chosasunthika chachitsulo chidzawonongeka pansi pa mphamvu, mapindikidwe panthawiyi akhoza kugawidwa m'njira ziwiri: mapindikidwe apulasitiki ndi mapindikidwe otanuka.

1. Kuwonongeka kwa pulasitiki sikudzatha pamene mphamvu yakunja idzatha, ndipo chitoliro chachitsulo chosasunthika chidzadutsa kusinthika kosatha.
2. Elastic deformation imatanthawuza kuti pansi pa chikhalidwe cha mphamvu yakunja, pamene mphamvu yakunja ikutha, kusinthika kudzatha.

Mphamvu zokolola ndizofunikanso kupsinjika kwa chitoliro chopanda msoko ikayamba kupangidwanso ndi pulasitiki, koma chifukwa chakuti zinthu zomwe zimawonongeka sizimadutsa mapindikidwe apulasitiki odziwikiratu akatambasulidwa ndi mphamvu yakunja, zinthu za ductile zokha zimakhala ndi mphamvu zokolola.

Apa, mphamvu ya zokolola za chitoliro chosasunthika chomwe timatchula ndi malire a zokolola pamene kukolola kumachitika, komanso kupsinjika kwa micro-pulasitiki deformation.Mphamvu ikakhala yayikulu kuposa malire awa, gawolo lidzalephera mpaka kalekale ndipo silingabwezeretsedwe.

Zinthu zakunja zomwe zimakhudza mphamvu ya zokolola za mapaipi opanda msoko ndi: kutentha, kuchuluka kwa kupsinjika, komanso kupsinjika.Pamene kutentha kumachepa ndipo kuchuluka kwa zovuta kumawonjezeka, mphamvu zokolola za chitoliro chosasunthika chachitsulo chimawonjezekanso, makamaka pamene chitsulo chokhazikika pa thupi chimakhudzidwa ndi kutentha ndi kupanikizika, zomwe zidzachititsa kuti chitsulo chikhale chochepa.Chikoka pa chikhalidwe cha kupsinjika maganizo ndi chofunika kwambiri.Ngakhale mphamvu ya zokolola ndi index yofunikira yowonetsera momwe zinthu zopangidwira zimagwirira ntchito, mphamvu zokolola zimakhala zosiyana chifukwa cha zovuta zosiyanasiyana.
Zomwe zimakhudza mphamvu zokolola ndizo: mgwirizano, bungwe, kapangidwe, ndi chikhalidwe cha atomiki.Tikayerekeza mphamvu ya zokolola za zitsulo zopanda msoko ndi zoumba ndi ma polima, titha kuwona kuchokera pamenepo kuti chikoka cha zomangira ndi vuto lalikulu.
