Course description

Engineering Vibration I: Introduction: Single-degree-of-freedom Systems

This course is an introduction to exploring the topic of engineering systems undergoing vibration. The methods taught in the course are used to predict the response of engineering structures to various types of input and to analyze the resulting vibratory motion. The free vibration of Single Degree-of-Freedom (SDOF) systems will be the focus of this course.
