Kusankhidwa kwa zinthu zoyenera ndikofunikira pakupanga kwathunthu zinthu zopangira pulasitiki. Zofunikira pakufunsira ntchito nthawi zonse kumayendetsa kufunikira kwa zinthu zina monga kukana kwamankhwala, kulimba kwamphamvu, kukana kukhudzidwa, kapena ductility. Tili ndi chidziwitso komanso chidziwitso chokomera zida zoyenera pazosowa zanu zofunikira, mosasamala kanthu za makulidwe, kuuma, kusinthasintha, komanso magwiridwe antchito. Gulu lathu laukadaulo limatha kupenda ndikuwunika momwe makinawo amagwirira ntchito, kulimbana ndi mankhwala, komanso mtengo wazinthu zofunikira.
