Challenge Problems
Push your limits with advanced challenges
A column with a length of 8 m and cross-sectional area of 200 cm² is fixed at both ends. It has a Young’s modulus of 210 GPa. Calculate the critical load at which it will buckle.
💡 Hint: Pay attention to the conversion of units and the effective length.
Discuss the effect of introducing an initial 1 cm indentation on a column with a slenderness ratio of 200. How would this affect the buckling load?
💡 Hint: Consider how real-world imperfections can cause deviations from theoretical predictions.
