Challenge Problems
Push your limits with challenges.
Question 1
A given damped oscillation equation is y(t)=e^(-0.3t)(5cos(4t)+2sin(4t)). Calculate the damping ratio and explain its significance.
💡 Hint: Use the form ζ = c / 2√(mk) to interpret the response characteristics.
Question 2
A bridge's vibrations follow y(t)=e^(-1.1t)(3cos(2.5t)+2sin(2.5t)). What implications does this have for structural integrity?
💡 Hint: Consider how quick decay affects resonance and safety.
