Trik mengira-ngira bobot besi kerikil: Diameter x Diameter x 6165 x 12 (m) = Ukuran (kg)







Sengkang = diameter besi semen (m)







Ukuran jenis logam = 7850 kg/m3







angka 6165 = didapat dari 0, 25 x 3. 14 x Berat jenis besi















Jalan menghitung repot besi strip: Tebal x Lebar x 7850 (kg/m3) x 6 (m) = Berat (kg)







Tebal = tebal ferum strip (m)







Lebar = lebar minyak patra strip (m)







Berat ru
