Question 1
An engineer designs a system where the mass m = 10 kg, stiffness k = 1000 N/m, and critical damping is applied. Determine the damping coefficient that would achieve critical damping.
💡 Hint: Remember the relationship between mass, stiffness, and damping for critical damping.
Question 2
A system resonates at a natural frequency of 2 Hz. What would be the implications if a forcing frequency of 2 Hz were continuously applied?
💡 Hint: Consider the consequences of matching frequencies in engineering designs.
