A steel I-beam section is subjected to a bending moment of 96 kN-m. The moment of inertia of the
beam section is 24,000 cm4. The bending stress at 100 mm above the neutral axis of the beam in
MPa will be ____________
 
Important : you should answer only the numeric value
    Correct answer is '40'. Can you explain this answer?

    Solution: Bending stress = 96x1000x0.1/24000 X 10^-8 = 40 x 10^6 Pa = 40MPa
    Bending stress = (My)/I
    M = the internal bending moment about the section‘s neutral axis
    y = the perpendicular distance from the neutral axis to a point on the section
    I = the moment of inertia of the section area about the neutral axis

    Given data:
    Bending moment, M = 96 kN-m
    Moment of inertia, I = 24,000 cm^4
    Distance from the neutral axis, y = 100 mm = 0.1 m

    Formula used:
    Bending stress, σ = (M*y)/I

    Calculation:
    Substituting the given values in the formula, we get
    σ = (96*0.1)/24000
    σ = 0.0004 MPa

    Rounding off the answer to the nearest integer, we get
    σ = 40 MPa

    Therefore, the bending stress at 100 mm above the neutral axis of the beam is 40 MPa.
