This playlist is made up of short videos, each discussing a concept from Strength of materials (mechanics of materials). This is not simply a "class" as you can watch these in any order. However, Part 1 is recommended if you are not familiar with stress and strain.
This playlist discusses a series of topics in the area of kinematics. I try to pick topics that give my students the most trouble and elaborate with examples and detailed explanations. If you are taking kinematics or dynamics you can use this playlist and watch the videos in any order.
