This is an educational video created to supplement the “Mechanics of Materials” course at the Colorado School of Mines. Each video is uniquely linked to a fruit name to facilitate searching for videos. A complete list of videos may be found at https://sites.google.com/site/ceen311/. Most of the videos have been designed without audio intentionally, so students may conveniently view the videos on their smartphones. I recommend that you pause the video, copy down the problem, and work it yourself. Then check yourself with the video solution. Happy studying! -SR
