Roof Live Load when Tributary Area Les in Range 200 to 600 square feet Solution

Follow our step by step solution on how to calculate Roof Live Load when Tributary Area Les in Range 200 to 600 square feet?

FIRST Step Consider the formula
Lf=20⋅(1.2-0.001⋅At)⋅R2
Next Step Substitute values of Variables
∴ Lf=20⋅(1.2-0.001⋅2182.782ft²)⋅0.9
Next Step Convert Units
∴ Lf=20⋅(1.2-0.001⋅202.7871m²)⋅0.9
Next Step Prepare to Evaluate
∴ Lf=20⋅(1.2-0.001⋅202.7871)⋅0.9
Next Step Evaluate
∴Lf=17.9498324977397N
LAST Step Rounding Answer
∴Lf=17.9498N
