I-Rebarifomula yokubala ubunzima

Ifomula: ububanzi mm × ububanzi mm × 0.00617 × ubude m

Umzekelo: I-Rebar Φ20mm (ububanzi) × 12m (ubude)

Ukubala: 20 × 20 × 0.00617 × 12 = 29.616kg

 

Umbhobho wentsimbiifomula yobunzima

Ifomula: (ububanzi obungaphandle - ubukhulu bodonga) × ubukhulu bodonga mm × 0.02466 × ubude m

Umzekelo: umbhobho wentsimbi oyi-114mm (ububanzi obungaphandle) × 4mm (ubukhulu bodonga) × 6m (ubude)

Ukubala: (114-4) × 4 × 0.02466 × 6 = 65.102kg

 

Intsimbi ethe tyabaifomula yobunzima

Ifomula: ububanzi becala (mm) × ubukhulu (mm) × ubude (m) × 0.00785

Umzekelo: intsimbi esicaba eyi-50mm (ububanzi becala) × 5.0mm (ubukhulu) × 6m (ubude)

Ukubala: 50 × 5 × 6 × 0.00785 = 11.7.75 (kg)

 

Ipleyiti yentsimbiifomula yokubala ubunzima

Ifomula: 7.85 × ubude (m) × ububanzi (m) × ubukhulu (mm)

Umzekelo: ipleyiti yentsimbi eyi-6m (ubude) × 1.51m (ububanzi) × 9.75mm (ubukhulu)

Ukubala: 7.85×6×1.51×9.75=693.43kg

 

Ukulinganaintsimbi ye-engileifomula yobunzima

Ifomula: ububanzi becala mm × ubukhulu × 0.015 × ubude m (ubalo oluqikelelweyo)

Umzekelo: I-engile 50mm × 50mm × 5 ubukhulu × 6m (ubude)

Ukubala: 50 × 5 × 0.015 × 6 = 22.5kg (itheyibhile ye-22.62)

 

Intsimbi ye-engile engalinganiyo ifomula yobunzima

Ifomula: (ububanzi becala + ububanzi becala) × ubukhulu × 0.0076 × ubude m (ubalo oluqikelelweyo)

Umzekelo: I-engile 100mm × 80mm × 8 ubukhulu × 6m (ubude)

Ukubala: (100 + 80) × 8 × 0.0076 × 6 = 65.67kg (Itheyibhile 65.676)
