Challenge Problems
Push your limits with advanced challenges
You have a concrete rod with a diameter of 150 mm and a length of 300 mm which can withstand a maximum tensile load of 200 kN before failing. Calculate the tensile strength.
💡 Hint: Make sure to convert all units to mm for accurate calculation.
A structural engineer needs to ensure that the bond strength of concrete and steel bars meets the requirement. If an embedded steel bar with a diameter of 16 mm provides a maximum load of 300 kN, calculate the average bond stress.
💡 Hint: Remember to convert diameters to the same unit for bond stress assessment.
