What is the neutral axis of a beam cross-section?
Answer: The axis along which bending stress is zero
The neutral axis is the line through a cross-section where bending stress is zero, separating zones of tension and compression.
Which equation is used to calculate the bending stress at a point in a beam cross-section?
Answer: σ = My/I
The flexure formula σ = My/I relates bending stress to the bending moment M, distance from neutral axis y, and moment of inertia I.
What does the moment of inertia (I) measure in structural beam design?
Answer: Cross-section resistance to bending
The area moment of inertia represents how the cross-sectional area is distributed about the neutral axis, directly affecting bending resistance.
A column that fails by sudden lateral deflection under compressive load is experiencing which phenomenon?
Answer: Buckling
Buckling is the sudden lateral instability of a slender compression member when the applied load reaches the critical (Euler) buckling load.
In structural engineering, what is the term for the maximum load a structure can support before failure?
Answer: Ultimate load
The ultimate load (or collapse load) is the maximum load at which a structure reaches its limit state and can no longer safely carry additional force.
Which AISC design method divides nominal strength by a safety factor to obtain allowable stress?
Answer: Allowable Stress Design (ASD)
Allowable Stress Design (ASD) divides the nominal member strength by a safety factor (Ω) to establish the permissible working stress.
