Planned Learning Activities and Teaching Methods

The course on mechanical vibrations employs a variety of teaching and learning methods to enhance student understanding and engagement. Lectures are utilized to deliver theoretical concepts and fundamental principles, providing students with a solid foundation in the subject matter. These lectures are supplemented with practical examples, real-world applications, and case studies to illustrate the relevance of mechanical vibrations in engineering practice. Additionally, hands-on laboratory sessions allow students to experiment with vibration measurement techniques, modal analysis, and vibration control strategies, reinforcing theoretical concepts through practical application. Furthermore, interactive discussions, group activities, and problem-solving exercises encourage active participation and critical thinking skills development among students. Through this multifaceted approach, students gain both theoretical knowledge and practical skills, preparing them for future endeavors in the field of mechanical engineering.
