Challenge Problems
Push your limits with advanced challenges
You have a concrete specimen that can withstand a maximum load of 80 kN and has a cross-sectional area of 0.02 m². Calculate the compressive strength in MPa.
💡 Hint: Convert your units correctly before performing the calculation!
A concrete beam of size 150 mm x 150 mm x 700 mm fails under a load of 12 kN when tested for flexural strength using a third-point loading mode. Compute the modulus of rupture.
💡 Hint: Check which dimensions correspond to the beam size when using the formula.
