Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for calculating deflection at mid-span?
- Δ = 5wL^4 / 384EI
- Δ = wL^3 / 48EI
- Δ = PL^3 / 3EI
💡 Hint: Recall the context of mid-span deflection.
Question 2
True or False: An increase in modulus of elasticity will always decrease beam deflection.
- True
- False
💡 Hint: Think about why stiffer materials bend less.

Challenge Problems
Push your limits with challenges.
Question 1
A beam has a span of 3 m with a distributed load of 8 kN/m and E = 150 GPa, I = 200×10^6 mm⁴. Calculate the deflection.
💡 Hint: Remember to switch to consistent units.
Question 2
Explain how an increase in moment of inertia would qualitatively affect deflection in real applications.
💡 Hint: Think about how beams resist bending.
