Class/laboratory schedule

The class meets for lectures, computer demostrations and laboratory work in two 1.5 hour classes.

There are 6 to 8 laboratory exercises assigned as group or individual projects which require additional student lab work outside of class.

Results of the assigned exercises are presented orally to the class as a group or individually.

Contribution of course to meeting the professional component

This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.

The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.

Experimental Vibrations and Dynamic System Analysis strongly contributes to the students understanding of health & safety when working in not only a laboratory environment but also with dynamic systems. There is significant emphasis placed on hands-on operation of complex dynamic systems and issues of control of the systems.

Relationship of course to undergraduate degree program objectives and outcomes

This course serves students in a variety of engineering majors. The information below describes how the course contributes to the college's educational objectives.

This course provides a unique, hands-on opportunity for students to investigate and verify their knowledge of mathematics and science using engineering tools, techniques and skills. This course provides the student a real world, hands-on environment to design, conduct, analyze and interprete experimental investigations of dynamic systems, sensors, computer based data acquisition, and associated signal conditioning equipment. Students work in teams to identify, formulate and solve engineering problems using both mathematical models and physical configurations. Student teams are expected to produce a written report using computer based word processing linked to software applications which allow mathematical definition as well as experimental data reduction. Teams present orally and defend the conclusions they reach from a combined modelling and testing task. These presentations are aided by computer based virtual experiment display and presentation software. This course relies heavily on students developing skills of independent thinking, topic research and information retrieval. It greatly enhances skills necessary for live long learning.

Assessment of student progress toward course objectives

Assessment of understanding and learning is achieved through evaluation of written reports, oral presentations, and the successful design and completion of subsequent laboratory exercises.

Through the semester each laboratory exercise builds on the preceeding exercise. To move on successfully students must have a firm understanding of the previous material.

Each exercise is introduced with a basic list of defined objectives. Teams must expand these basic objectives or supplement them with their own investigations linked to the basic objectives.

There are no formal homework problems, reading assignments or examinations. Students must expand their learning by individual searches and team interaction. Work is assessed in the team oral presentations. Class members,as the audience, are required to define what the presenting teams have done well, what they could do to improve their investigation and presentation, and to define what they, the audience, learned from the team presentation.

Class members as well as the instructor assess the team efforts from the oral presentations.

Student assess whether the defined course objectives are being met.
