Notes to instructors

Contents of lab

Each module contains short narrated presentations of basic theory, test equipment and test procedure. This is followed by virtual experiments, consisting of video of tests with live graphing of data. Data from a number of experiments, along with images of the broken samples are available for students to download and analyze. The lab manual suggests analyses and questions for the student. A limited amount of reference material is also available, giving definitions and keywords, hints on unit conversions and hints on analyzing and graphing the data in Matlab and Excel.

Labs for different levels of students and custom building labs for your own use

The lab is built in a modular fashion, allowing sections to be re-used for students of various levels. For example, all of the basic information contained in the lab for engineering technology students is re-used in the lab for four students. The lab for four year students contains supplementary information on biological materials.

You are invited to either use one of the three labs provided, or to custom build a lab for your own students by creating your own home page linking just the web pages you want your students to see. You could also write additional pages to supplement or replace what is here, but still use the data and videos provided. A site map giving the URL of each section of the site and a brief description follows.

Suggested Uses

  1. As a laboratory exercise. At Cornell we will supplement our existing physical lab with this virtual lab exercise. Students will write and turn in a lab report based on the data and results from the experimental data.
  2. As a homework exercise. Students could be assigned homework that asks them to perform a limited amount of analysis of the data, finding yield stress and elastic modulus, for example, or comparing measured torsional stiffness to theory.
  3. As in in-class demonstration. Videos of the experiments and live graphs of the tests could be shown during lecture to demonstrate torsional deformation and fracture. Brittle and ductile materials can be compared to demonstrate their failure modes.
