Correct Answer - Option 4 : 7850 × 10
3 g/m
3
Explanation:
The properties of structural steel, as per clause 2.2.4 of IS 800:2007, for use in design, may be taken as given in clauses 2.2.4.1 and 2.2.4.2 of the code.
Physical Property |
Value |
Unit mass of steel, p |
7850 kg/m3 |
Modulus of elasticity, E |
2.0 × 105 N/mm2
|
Poisson ratio, μ |
0.3 |
Modulus of rigidity, G |
0.769 × 105 N/mm2
|
Coefficient of thermal expansion, Cx
|
12 × 10-6/ºC
|
Since,
1 kg = 103 g
Therefore, 7850 kg/m3 = 7850 × 103 g/m3
