Live Load Moment given Maximum Steel Stress as per AISC Specifications Solution

Follow our step by step solution on how to calculate Live Load Moment given Maximum Steel Stress as per AISC Specifications?

FIRST Step Consider the formula
ML=(σmax⋅Ss)-MD
Next Step Substitute values of Variables
∴ ML=(2.18N/mm²⋅150mm³)-280N*mm
Next Step Convert Units
∴ ML=(2.2E+6Pa⋅1.5E-7m³)-0.28N*m
Next Step Prepare to Evaluate
∴ ML=(2.2E+6⋅1.5E-7)-0.28
Next Step Evaluate
∴ML=0.047N*m
LAST Step Convert to Output's Unit
∴ML=47N*mm
