A structural engineer is designing a bridge that must withstand heavy wind and potential earthquakes. Analyze the ideal damping ratio they should target and justify your reasoning.
💡 Hint: Think about how dynamic forces influence the structure.
Calculate the damping ratio for a mass-spring system with a damping coefficient of 20 Ns/m, mass of 10 kg, and stiffness of 500 N/m.
💡 Hint: Ensure you correctly apply the values in the formula.
