Challenge Problems
Push your limits with challenges.
Question 1
A truss is subjected to an axial load of 5000 N. If the area is 0.002 m², and Young's modulus is 200 GPa, calculate its axial deformation.
💡 Hint: Recall δ=PL/AE, and think about how you can rearrange it.
Question 2
If a beam of length 4 m has a moment of inertia of 0.0002 m⁴ and is subjected to a bending moment of 1000 N·m, find the beam’s deflection.
💡 Hint: Look for how E affects deflection in bending.
