Challenge Problems
Push your limits with advanced challenges
A structural engineer must design a concrete beam that can hold a load of 50 kN. Based on experimental testing, the beam’s flexural strength is calculated as 5 N/mm². Compute the width and depth required if the span length is 2 m.
💡 Hint: Think about rearranging the formula to find dimensions based on desired strength.
If a concrete cylinder is tested till failure and shows a split tensile strength of 1.5 N/mm², compute the maximum load applied if the diameter is 300 mm and length is 600 mm.
💡 Hint: Apply the formula while solving for P.
