  1. I am strongly encouraging my students to review your videos, and as a first time mechanics teacher, they are a great help to me as well.

    I am very interested in the medium you use to produce your videos. (Also Stress and design Part 2 is a private video).

    If you wouldn't mind emailing me knleme at rit dot edu I'd appreciate it.

    Thank you!
