Challenge Problems
Push your limits with challenges.
Question 1
A concrete beam (Young's modulus = 30 GPa) is supported at both ends and loaded in the middle by a 15 kN force. Calculate the deflection at the center of the beam given it has a length of 4 m and a rectilinear cross-section of 0.25 m².
💡 Hint: You will need to calculate the moment of inertia for the rectangular cross-section.
Question 2
Determine the amount of elongation in a 3 m long copper wire (Young's modulus = 110 GPa) when a force of 4 kN is applied.
💡 Hint: Make sure to account for the cross-sectional area in your calculation.
