1.58kg per metre
Depends upon the density of the metal.
In order for your to know the weight must know the thickness of the angle bar.
45
The atmospheric pressure is roughly 1 bar, or 100,000 pascal. That means 100,000 newton per square meter (equivalent to the mass of about 10 tons). Actually, that's the approximate pressure at sea level; the pressure (force or weight per square meter) varies a lot depending on the altitude.
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
0.618
3.85
D^2/162
mass=density/volume
1.58kg per metre
0.887 kg per m
Type your answer here... 3.85
aruond 30 kilo
0.395kg/rm
around 2.67kg
DxD/162 this is the formula for finding unit weight of steel
