← HistoryWhich structural consequence results when compressive force exceeds Euler's critical load in a timber column?
A)Tensile fracturing at the base
B)Buckling perpendicular to the load✓
C)Shearing along the grain
D)Crushing due to material yield
💡 Explanation
When compressive force exceeds Euler's critical load, elastic instability (buckling) occurs because the column can no longer withstand the axial load without lateral deflection. Therefore buckling results, rather than fracturing, shearing, or crushing which require different stress orientations or material properties.
