Kuyesa kwamphamvu ndi njira yofunika kwambiri mu sayansi ya zinthu ndi uinjiniya womwe umagwiritsidwa ntchito kudziwa mphamvu ndi kutha kwa zida. Kuyezetsa kumeneku kumachitidwa pogwiritsa ntchito chida chapadera chotchedwa tensile tester, chomwe chimadziwikanso kuti tensile tester kapenamakina oyesera amphamvu. Makinawa adapangidwa kuti agwiritse ntchito zovuta zowongolera pazitsanzo zakuthupi, kulola ofufuza ndi mainjiniya kuyeza momwe amayankhira kupsinjika ndi kupsinjika.
Makina oyezera zitsulo ndi zida zofunika kwambiri zowunika momwe zinthu zimagwirira ntchito, kuphatikiza zitsulo, mapulasitiki, zida zophatikizika, ndi zina zambiri. Zimagwira ntchito yofunika kwambiri pakuwongolera, kufufuza ndi chitukuko, komanso kuwunika magwiridwe antchito azinthu m'mafakitale osiyanasiyana. Makinawa amatha kuyika zitsanzo zakuthupi kuti ziwonjezeke mpaka zitafika pachimake, kupereka chidziwitso chofunikira pamapangidwe ndi kupanga.
Wambamakina oyesera amphamvukamangidwe kamakhala chimango chonyamula katundu, chogwirizira, ndi njira yoyezera mphamvu. Choyimira chonyamula chimagwira ntchito ngati chothandizira pamayeso ndipo chimakhala ndi zigawo zomwe zimagwiritsa ntchito mphamvu zamagetsi. Ma clamp amagwiritsidwa ntchito kusunga chitsanzocho motetezeka ndikusamutsa mphamvu yogwiritsidwa ntchito, kuwonetsetsa kuti zitsanzozo zimakhalabebe panthawi yoyesedwa. Makina oyezera mokakamiza nthawi zambiri amakhala ndi ma cell onyamula ndi ma extensometers omwe amajambula mphamvu yomwe imagwiritsidwa ntchito ndikusintha kwazinthu.
Makina oyesera ma tensile amapezeka m'makonzedwe osiyanasiyana kuti agwirizane ndi kukula kwa zitsanzo, mawonekedwe ndi zofunikira zoyesa. Makina ena amapangidwa kuti aziyesa kuchuluka kwazitsulo ndi ma alloys, pomwe ena amapangidwa kuti aziyesa ma polima, nsalu, ndi zinthu zina zopanda zitsulo. Kuphatikiza apo, mitundu yotsogola imatha kukhala ndi zipinda zachilengedwe zoyesera pansi pa kutentha kwina ndi chinyezi kuti mumvetsetse bwino momwe zinthu zilili.
Ntchito ya amakina oyesera amphamvukumaphatikizapo kukhala ndi chitsanzo cha zinthu mkati mwa fixture, kugwiritsa ntchito kuchulukirachulukira kwazovuta, ndi kujambula kupsinjika kofananira ndi kupsinjika. Njirayi imathandizira mainjiniya kupanga ma curve opsinjika omwe amawonetsa momwe zinthu zimagwirira ntchito pamavuto ndikupereka zidziwitso zofunikira pamakina ake monga kulimba kwamphamvu, kulimba kwa zokolola, komanso kutalika.
Mu kafukufuku ndi chitukuko,kuyezetsa kolimbamakina amathandizira kuwunika momwe zida zatsopano zilili ndikuwonetsetsa kuti zikuyenera kugwiritsidwa ntchito mwapadera. Kwa opanga, makinawa ndi ofunikira kuti atsimikizire kuti zinthu zili bwino komanso zogwirizana ndi zinthu zomwe zimagwiritsidwa ntchito pazinthu zawo, potsirizira pake zimathandizira ku chitetezo ndi kudalirika kwa chinthu chomaliza.
Mukakhala ndi chidwi ndi chilichonse mwazinthu zomwe zikutsatira mukamawona mndandanda wazogulitsa, chonde omasuka kulumikizana nafe kuti mufunse mafunso.
