Challenge Problems
Push your limits with advanced challenges
Given a concrete mix with a known compressive strength of 30 MPa, estimate the maximum load a cube with dimensions 150 mm × 150 mm could withstand.
💡 Hint: Use the formula for compressive strength to find maximum load.
If a test shows a bond strength of 1.5 N/mm² for a reinforcing bar of diameter 12 mm and embedded length of 100 mm, calculate the maximum load applied in the pull-out test.
💡 Hint: Substitute values into the bond strength equation to find P.
