Challenge Problems
Push your limits with advanced challenges
A steel beam is designed with a width of 12 inches and a thickness of 0.5 inches. Determine if it qualifies as compact based on the width-to-thickness ratio for flanges.
💡 Hint: Always reference the given formulas for critical ratios.
A beam experiences a load causing a moment of 5000 in-lbs. Calculate the necessary plastic section modulus given that the yield strength is 36 ksi.
💡 Hint: Use units correctly to ensure accurate calculations.
