Challenge Problems
Push your limits with challenges.
Question 1
A suspension bridge has a mass of 2000 kg and a stiffness of 12000 N/m. Calculate its natural frequency.
💡 Hint: Use the formula for natural frequency.
Question 2
A designer needs to increase the stiffness of a structure to ensure it vibrates at a different frequency. If the current stiffness is 5000 N/m and mass remains constant at 1000 kg, what stiffness would achieve a natural frequency of 3 rad/s?
💡 Hint: Rearrange the formula accordingly.
