Maximum Unit Stress in Steel Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Stress = (Dead Load Moment/Section Modulus of Steel Beam)+(Live Load Moment/Section Modulus of Transformed Section)
σ_max = (M_D/S_s)+(M_L/S_tr)
This formula uses 5 Variables

Variables Used

Maximum Stress - (Measured in Pascal) - Maximum Stress is the stress that material or section withstands before its fracture.
Dead Load Moment - (Measured in Newton Meter) - Dead Load Moment is the moment generated due to dead load acting to member.
Section Modulus of Steel Beam - (Measured in Cubic Meter) - Section Modulus of Steel Beam is a geometric property for a given cross-section used to design steel beams or flexural members.
Live Load Moment - (Measured in Newton Meter) - Live Load Moment is the moment generated due to live load acting to member.
Section Modulus of Transformed Section - (Measured in Cubic Meter) - Section Modulus of Transformed Section is the MOI of a composite beam transformed into an equivalent cross-section (called the transformed section) of an imaginary beam composed of only one material.

STEP 1: Convert Input(s) to Base Unit

Dead Load Moment: 280 Newton Millimeter --> 0.28 Newton Meter (Check conversion here)
Section Modulus of Steel Beam: 150 Cubic Millimeter --> 1.5E-07 Cubic Meter (Check conversion here)
Live Load Moment: 115 Newton Millimeter --> 0.115 Newton Meter (Check conversion here)
Section Modulus of Transformed Section: 250 Cubic Millimeter --> 2.5E-07 Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_max = (M_D/S_s)+(M_L/S_tr) --> (0.28/1.5E-07)+(0.115/2.5E-07)

Evaluating ... ...

σ_max = 2326666.66666667

STEP 3: Convert Result to Output's Unit

2326666.66666667 Pascal -->2.32666666666667 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

2.32666666666667 ≈ 2.326667 Newton per Square Millimeter <-- Maximum Stress
