2.when we find the weight of 1meter iron road we help the following formula
dxd162 .what is 162 plz tell me
Answer Posted / shiv jaiswal
we know that unit weight of steel rod is 7850 kg/m^(3) and W/l=unit weight*area
so weight per unit length=7850*((π*d*d)/4)*10^(-6)=6.16*10^(-3)d*d=d*d/162
where, d in mm
