Question 1.
Define the term 'critical load'.
Show hintHide hint
Remember, it's linked to buckling failure.
Question 2.
What is the formula for Euler's critical load?
Show hintHide hint
Look at the components: identify E, I, and Leff.
3Question 3.
What is the formula for calculating the critical load of a column?
- Pcr = π²EI/(Leff)²
- Pcr = 2EI/(πLeff)
- Pcr = EI/(π²Leff)
Show hintHide hint
Remember the relationship between Pcr, E, I, and Leff.
4Question 4.
True or False: Eccentric loading can cause bending stresses in columns.
- True
- False
Show hintHide hint
Consider what happens when loads are applied off-center.
Question 5.
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.
Show hintHide hint
Break down the formula into parts and solve step-by-step.
Question 6.
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.
