• Develop numerical and analytical skills leading to a problem-solving thinking.
• Understand and apply linear vibration theory.
• Apply both kinematics and kinetics principles for rigid body plane motion and vibration (damped/forced), and develop dynamics problem-solving skills for mechanical components
