Imatengera chitsulo choyenera kwambiri pa matepi opangidwa m'nyumba, ndipo imatsitsidwa mosamala pakatha nthawi zambiri ndi mankhwala ena a vacuum kutentha.Ukadaulo wogwiritsidwa ntchito ndi woyenera pokonza ma alloys ambiri ndi zitsulo.Amagwiritsidwa ntchito pamanja, makina obowola, ma lathes, makina ojambulira oyera, ndi zina zambiri.
Kutembenuza ulusi wa metric ndi inchi: kugwiritsa ntchito zoyika za waya kuti musinthe metric ←→inchi ←→mabowo amtundu wapadziko lonse lapansi, ndiyosavuta, yachangu, yotsika mtengo komanso yothandiza, yoyenera kutengera zinthu zilizonse zolowa ndi kutumiza kunja.
Kukana kutentha ndi kukana kwa dzimbiri: Chifukwa chakuti pamwamba pa ulusi wa waya ndi wosalala kwambiri, amatha kuchepetsa mkangano pakati pa ulusi wamkati ndi wakunja, ndipo zinthuzo zimakhala ndi mawonekedwe a kutentha kwambiri komanso kukana kwa dzimbiri.Itha kugwiritsidwa ntchito m'zigawo zomwe nthawi zambiri zimapasuka ndikuyika ndikuyika mabowo omwe amazunguliridwa pafupipafupi kuti atalikitse moyo wake wautumiki.
Malo okulirapo: Itha kugwiritsidwa ntchito pazigawo zopyapyala zamakina zomwe zimafuna kulumikizidwa mwamphamvu koma sizingachulukitse kukula kwa mabowo.
