How to Calculate the Weight of Steel? The Formula for Calculating the weight of Steel bars are D²/162 for Kg/m and D²/533 for Kg/foot. Where D denotes the diameter of steel bars, and 162 denotes a constant value . Derivation of D²/162 or  D²/533 Formula Consider a steel bar whose diameter  D and Length are L. The density of the steel bar is 7850 kg/m3. Density = Weight / Volume Weight of steel bar  = Volume of steel Bar x Density of steel Weight of steel bar =  (Cross-sectional area of steel rod x Length) x 7850kg/m3 Weight of steel bar =  (22/7 x (D2/4) x L) x 7850kg/m3 Weight of steel bar =           3.14 (D2/4) x  1000 mm x  (7850/1000 x 1000 x 1000) mm Weight of steel bar = 3.14 (D2/4) x 0.00785 Weight of steel bar = 0.06162 x D2 Weight / Meter =  (D2/1/0.06162) = D2 / 162 The formula is  Weight of Steel Bar = [D2/162] x  L  for  Kg/m. The formula is  Weight of Steel Bar = [D2/533] ...

  Introduction of  Drawing Instrument What will you learn from this Chapter? In this chapter, you will learn   The various uses for instruments in drawings Introduction of Drawing Drawings assist us in transforming our ideas and thoughts into a finished product. Engineering industries also require and use drawings because they are required and employed at various phases of the development of an engineering product. Engineering drawing is distinct from artistic drawing, which is intended to convey aesthetic, philosophical, and abstract concepts.   Drawing Board Soft wooden platens make up the drawing board. It is necessary to ensure that the drawing board's working surface is almost perfectly planned. The usual drawing board sizes are indicated in the table below. For engineering students, a D2 size drawing board is usually recommended. The usual drawing board sizes are listed below. Designation Sheet Size L x W (mm) ...
