Question 1
What is the formula for calculating the critical load of a column?
- Pcr = π²EI/(Leff)²
- Pcr = 2EI/(πLeff)
- Pcr = EI/(π²Leff)
💡 Hint: Remember the relationship between Pcr, E, I, and Leff.
Question 2
True or False: Eccentric loading can cause bending stresses in columns.
- True
- False
💡 Hint: Consider what happens when loads are applied off-center.

Challenge Problems
Push your limits with challenges.
Question 1
A concrete column of effective length 4m with Young's modulus of 25 GPa and a moment of inertia of 0.001 m⁴ was subjected to a load. Calculate the critical load it can withstand before buckling.
💡 Hint: Break down the formula into parts and solve step-by-step.
Question 2
Design a column to support an axial load of 15 kN, knowing it has a moment of inertia of 0.002 m⁴ and Young's modulus of 30 GPa. Determine the required effective length to prevent buckling.
💡 Hint: Ensure all units are consistent when calculating.
