Challenge Problems
Push your limits with challenges.
Question 1
A structure has stiffness k = 3000 N/m and mass m = 1500 kg. Calculate the natural frequency and discuss the implications of this frequency in earthquake scenarios.
💡 Hint: Recall the formula f = (1/2π) * √(k/m).
Question 2
Consider two buildings: Building A with a natural frequency of 5 Hz and Building B with a natural frequency of 2 Hz. Discuss the potential damage each might sustain during an earthquake of 3 Hz.
💡 Hint: Consider how matching frequencies can amplify destructive forces.
