Homework Statement
A mild steel column has a cross section of 100mm by 50mm. Assuming a safety factor of 6 calculate the load that it can safely support.
Homework Equations
Column material: mild steel
Column cross section: 100mm x 50mm
Safety factor: 6
On the basis that the tensile strength of steel is equivalent to its compressive strength and that there is no compressive stress value provided in the tables of my study module. I have used the average tensile stress value which is provided in my study material.
∴ Tensile stress of mild structural steel: 430 to 510 N/mm2
∴ Average tensile stress of mild structural steel: 470N/mm2
Is this correct?
The Attempt at a Solution
Area = 100mm x 50mm = 5,000mm2
σ = 470N/mm2 x 0.167 = 78.49N/mm2
∴ Load = Aσ
∴Load = 5,000mm2 x 78.49N/mm2 = 392,450N
Therefore the safe load that the column can support is 392,450N.
Is this correct, any help on this would be much appreciated.
Thanks
