1. Ukuqinisekiswa komgaqo womzimba wefomyula engundoqo
Umthetho woLondolozo lweMisa
Zonke iifomyula zisekwe kubume bomzimba be-m=ρ×V (ubunzima = ubuninzi × umthamo)
Ixabiso lokuxinana
Uxinaniso lwethiyori yealuminiyam esulungekileyo: 2,698 kg/m³ (20℃)
Ixabiso eliqikelelweyo le-2,700 kg/m³ lifanelekile kubalo lwamashishini (impazamo <0.1%)
2. Ukuqinisekiswa koBungqongqo beeFomula zeJometri
2.1. Ifomula yomthamo wejometri esemgangathweni
Izithintelo zefomula yetyhubhu yesikwere:
Oku kuyinyaniso xa ubukhulu bodonga lwetyhubhu bufana kwaye i-angle yangaphakathi i-angle echanekileyo (i-tube yangempela yesikwere inenguqu ejikelezileyo, kwaye impazamo yethiyori malunga ne-1-3%).
3. UQinisekiso lweYunithi yokuNxibelelana kweNkqubo
Uphando lwendawo yomngcipheko wokubala
4. ULungiso lokufaneleka kobuNjineli
4.1. Imbuyekezo yezinto ezingezizo
4.2. Ubungakanani bempembelelo yokunyamezela
Ukunyamezela ukutyeba ±10% → Ukutenxa ubunzima ±(8% ~ 12%) (amalungu anodonga olubhityileyo anovakalelo ngakumbi)
Isisombululo: W eyiyo = W ithiyori × (1 + Δt / t) ( Δt : ukutenxa kobukhulu)
5. Uvavanyo lweMida yoMda
Ukuqinisekiswa kwemeko egqithisileyo:
Ukuxinana kwemeko engaqhelekanga
7xxx ingxubevange (7075): Ubuninzi obulinganisiweyo 2.810 g/cm³ → Ukuba 2.7g/cm³ isetyenziswe ngempazamo, impazamo ngu +4.1%.
Itheyibhile yefomula
4t(A + B)- 4t² lubalo lobunjineli oluqhelekileyo olubalwa ngokuphinda-phinda iperimeter yecandelo ngobunzima bodonga kwaye emva koko kutsalwe iikona ezine.
Umzekelo wokubala:
1.6061 ipleyiti aluminiyam(1000 × 500 × 10 mm, ubude 2 m): W = 1000 × 500 × 2 × 0.0027 = 27 kg
2.7075 ityhubhu ejikelezayo(i-diameter yangaphandle 50 mm, ubukhulu bodonga 3 mm, ubude 1.5 m): W = [(50-3)×3×3.1416×1.5]×0.00283 ≈ 5.65 kg
3. Ityhubhu yesikwere(40×40×2mm, ubude 3m): W = [2×2×(40+40-4)×3]×0.0027×0.98 ≈ 2.42 kg
Ukuhamba okuCetyisiweyo
1. Khetha ingxinano → 2. Meta ubungakanani bokwenene → 3. Khetha imbuyekezo → 4. Bala ngefomula
