Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the correct equation for an undamped MDOF system?
- [M]{u¨(t)} + [C]{u˙(t)} + [K]{u(t)} = {f(t)}
- [M]{u¨(t)} + [K]{u(t)} = {f(t)}
- [C]{u˙(t)} + [K]{u(t)} = {f(t)}
💡 Hint: Focus on the absence of the damping term.
Question 2
True or False: The damping matrix [C] is included only in damped MDOF systems.
- True
- False
💡 Hint: Think about the effects of damping.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a two-degree-of-freedom MDOF system with mass matrix [M] = [2 0; 0 3] and stiffness matrix [K] = [4 -2; -2 3]. Derive the equation of motion for this system.
💡 Hint: Use the definition of MDOF systems and substitute the matrices.
Question 2
An MDOF system has an undamped response. How would you adjust the equation to account for damping, and what implications might that have?
💡 Hint: Consider how energy dissipation modifies overall response.
