Challenge Problems
Push your limits with advanced challenges
Given a concrete column with a known Modulus of Elasticity, calculate the expected stress at a strain of 0.0025. The ultimate compressive strength is 30 MPa.
💡 Hint: You will need to use concrete's characteristics to plug values into the modulus equation.
Analyze the potential failure mechanism in a structure designed with lower than necessary ultimate compressive strength. What consequences might arise?
💡 Hint: Consider the implications of inadequate material strength on structural safety.
