Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is flexural failure?

💡 Hint: Think about what happens when a beam is bent too much.

Question 2

Easy

Where does cracking typically initiate in flexural failure?

💡 Hint: Consider the part of the beam that experiences the most stress during bending.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What initiates flexural failure in a beam?

  • Compression zone
  • Tension zone
  • Shear zone

💡 Hint: Consider where stress accumulates during bending.

Question 2

True or False: An over-reinforced beam will crack before it crushes.

  • True
  • False

💡 Hint: Think about the relationship between reinforcement and failure mode.

Challenge Problems

Push your limits with challenges.

Question 1

Given a simply supported beam with a span of 10 meters and a concentrated load of 20 kN at its midspan, calculate the required area of steel reinforcement to prevent flexural failure, assuming a concrete compressive strength of 25 MPa and tensile strength of 2.5 MPa.

💡 Hint: Use the equation for bending moment: M = WL/4 for concentrated load.

Question 2

Analyze an existing beam that has started to show flexural cracks. Propose a remedial strategy for enhancing its structural integrity for future uses.

💡 Hint: Think about rehabilitation techniques used in construction.
