Giredi ya magwiridwe antchito 4.8
Mabagi a mtundu uwu angagwiritsidwe ntchito popangira mipando yamba, kukonza zinthu zamkati mwa zipangizo zapakhomo, zopepuka, komanso kukonza kwakanthawi kofunikira mphamvu zochepa.
Giredi ya magwiridwe antchito 8.8
Maboluti a mtundu uwu angagwiritsidwe ntchito pazinthu zamagalimoto, zolumikizira zazikulu za zida zamakanika, ndi zomangamanga zachitsulo; ndi mtundu wofala kwambiri wa mphamvu zapamwamba, womwe umagwiritsidwa ntchito polumikizira zofunika kwambiri zomwe zimafunika kupirira katundu waukulu kapena kugundana.
Giredi ya magwiridwe antchito 10.9
Maboluti amtunduwu angagwiritsidwe ntchito pamakina olemera (monga ma archer), ma clarical steel structures, ma connection a zida zothamanga kwambiri, ndi ma connection ofunikira a ma structure a steel structure; amatha kunyamula katundu wambiri komanso kugwedezeka kwambiri, ndipo amafunikira kwambiri kuti akhale odalirika komanso okana kutopa.
Giredi yochita bwino 12.9
Maboluti a mtundu uwu angagwiritsidwe ntchito m'mabwalo a ndege, makina apamwamba kwambiri, ndi zida za injini zothamanga; pazochitika zovuta kwambiri pomwe kulemera ndi voliyumu ndizofunikira komanso pomwe mphamvu yayikulu imafunika.
Chitsulo chosapanga dzimbiri A2-70/A4-70
Maboluti a mtundu uwu angagwiritsidwe ntchito pamakina ophikira chakudya, zida zamakemikolo, mapaipi akunja, zida zoyendera; malo owononga monga chinyezi, acid-base media kapena zinthu zofunika kwambiri paukhondo.
Kuyeza mphamvu ndi kuuma kwa mabotolo ndiye maziko ofunikira kwambiri pakusankha.
Imaimiridwa ndi manambala kapena manambala ophatikizidwa ndi zilembo, monga 4.8, 8.8, 10.9, A2-70.
Maboluti achitsulo: Zolemba zili mu mawonekedwe a XY (mwachitsanzo 8.8)
X (gawo loyamba la nambala):Imayimira 1/100 ya mphamvu yokhazikika (Rm), mu mayunitsi a MPa. Mwachitsanzo, 8 imayimira Rm ≈ 8 × 100 = 800 MPa.
Y (gawo lachiwiri la nambala):Imayimira nthawi 10 chiŵerengero cha mphamvu yogwira ntchito (Re) ku mphamvu yogwira ntchito (Rm).
Nthawi yotumizira: Disembala-29-2025
