Challenge Problems
Push your limits with advanced challenges
A W-section beam has a width of 10 inches, a thickness of 3/4 inch, and a yield strength of 50 ksi. Calculate its nominal strength and discuss the implications if the width varies.
💡 Hint: Ensure all dimensions are in the same units before calculations.
A channel section experiences a lateral load causing lateral torsional buckling. Explain how you would reinforce this section based on your understanding of nominal strength.
💡 Hint: Focus on mechanisms that reduce the moment and stabilize the beam.
