①Ka'idar hana harsashi na kayan yumbura
Tushen ka'idar kariyar sulke ita ce cinye makamashin majigi, rage shi, da sanya shi mara lahani.Yawancin kayan aikin injiniya na gargajiya, irin su kayan ƙarfe, suna ɗaukar makamashi ta hanyar nakasar filastik na tsarin, yayin da kayan yumbu ke ɗaukar makamashi ta hanyar tsarin murƙushewa.
Tsarin shayar makamashi na yumbu mai hana harsashi za a iya kasu kusan matakai uku:
