Answer / rajkumar s

(dia)^2/162

Answer / rj

Sq Dia / 164

Eg for 12mm rod

(12*12)/162

= 144/162

= .888 Kg/Mt

Answer / banambar pradhan

ANS- IF PER RUNNING METER IT IS D2/162KG/M, IF IN VOLUME
i.e7850kg/m3
EX-SUPPOSE DIA OF ROD 12MM AND LENGTH OF ROD 2METER,
CALCULATE THE WT OF ROD.
ANS-D2/162=12^2/162=0.8889KG/M, HERE 2M LENGTH SO
2*0.8889=1.778KG

Answer / munesh natrrajan

Weight of Steel For 1m Length=(Square of Bar Diameter)/162

For Example:

Take 8mm Diameter Bar Weight For 1m Length;i.e.

8*8/162=0.395Kg For 1m Length

Answer / mr.gurme santoshkumar v

d=diameter of bar or steel
=d^2/162 e.g. d=8mm
=64/162
=.395m/kg

Answer / mr.s.yuvaraj

Weight of bar per meter = Area of steel bar X Density of steel x Length of bar
= (3.14 x D2/4) x 7850 kg/m3 x 1000 mm
= (3.14 x D2/4) x 1000 x 7850 / (1000 x 1000 x 1000)
= D2 X 785.714285714286 x 0.00000785
= D2 X 0.006162
= D2 X 1/(0.006162)
= (D2/162.28)

Answer / gajendra singh

3.14(Pia)/4(d*d*0.00785)

Answer / ajay saini

use the normal formula
mass = volume x density
density of steel in india is 7850 kg/cum
use same units based of MKS system.

Answer / eng shah khalid

dia(mm)*dia(mm)* 0.00617 * length(m)= xxkg

Answer / anoop didwnaiya

Dia x Dia x .00619
ex- 8x8x.00619=.396
