Challenge Problems
Push your limits with advanced challenges
A concrete beam is tested and found to have a flexural strength of 5 N/mm². If the span is 300 mm, the width is 150 mm, and the depth is 250 mm, verify if the calculated flexural strength matches the test result.
💡 Hint: Make sure to ensure the units stay consistent while calculating.
You are tasked with testing the bond strength of concrete with reinforcement bars of different diameters (10 mm vs 20 mm). How does the diameter affect the bond stress, assuming the same load is applied?
💡 Hint: Think about how changing dimensions impact the surface area.
