Challenge Problems
Push your limits with advanced challenges
Design a beam to support a load of 5000 N applying proper AISC equations. Determine the necessary dimensions to prevent lateral torsional buckling.
💡 Hint: Consider moment calculations and compare them to the load.
You have a beam with known lengths and moment values. Calculate the C factor for varying load scenarios and determine which loading condition poses the greatest risk of lateral torsional buckling.
💡 Hint: Focus on understanding how varying moments affect the C factor.
