Maximum Unsupported Length of Compression Flange-2 Solution

STEP 0: Pre-Calculation Summary
Formula Used
Maximum Unbraced Length = 20000/((Yield Stress of Steel*Beam Depth)/Area of Compression Flange)
lmax = 20000/((Fy*d)/Af)
This formula uses 4 Variables
Variables Used
Maximum Unbraced Length - (Measured in Meter) - Maximum Unbraced Length also known as the unsupported length, is the largest distance along a structural member between the brace points.
Yield Stress of Steel - (Measured in Megapascal) - Yield Stress of Steel is the stress at which the material begins to deform plastically, meaning it will not return to its original shape when the applied force is removed.
Beam Depth - (Measured in Meter) - Beam Depth is the distance from the tension steel of the beam to the edge of the compression fibre.
Area of Compression Flange - (Measured in Square Meter) - Area of Compression Flange is the product of the length and depth of the compression flange of the beam.
STEP 1: Convert Input(s) to Base Unit
Yield Stress of Steel: 250 Megapascal --> 250 Megapascal No Conversion Required
Beam Depth: 350 Millimeter --> 0.35 Meter (Check conversion ​here)
Area of Compression Flange: 10500 Square Millimeter --> 0.0105 Square Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
lmax = 20000/((Fy*d)/Af) --> 20000/((250*0.35)/0.0105)
Evaluating ... ...
lmax = 2.4
STEP 3: Convert Result to Output's Unit
2.4 Meter -->2400 Millimeter (Check conversion ​here)
FINAL ANSWER
2400 Millimeter <-- Maximum Unbraced Length
