Eccentric Loading — the Secant Formula
Inside this lesson
- Explain why an eccentric load produces deflection from the start (no sharp bifurcation)
- Describe the P-δ effect that couples compression to bending
- Evaluate the secant formula for the maximum compressive stress
- Recognise the steep stress amplification as P approaches P_cr
