  1. complete waste of time and resources !!! it would be more intuitive if the course attacks some practical problems instead of power point presentations and equations without any practical significance..!!!

  2. Why is the torsion arrow always anticlockwise if the force is down? and clockwise if the force is up? is there a free body diagram explaining this?

  3. First, thank you for your effort. Both, the video uploader and the professor. The video is quite educational. The following might sound like I'm angry, but I'm just hoping to provide helpful feedback. Pardon my direct way of speech. It's a part of the freedom I've gained by using the Internet and it's hard to give up. I'm sure other "angry" comments are the same. No offense meant.

    Pass this on to the professor:
    – There's almost no difference between this video and how teachers explained stuff back when chalk and blackboard were considered modern.
    – Imagine as you're explaining to a 10 year old child. It's less stress for you and easier to grasp for them.
    – People give up on paying attention really fast, so get to the point faster.
    – Just mentioning an example is fine. Even helpful, as it gives you an image of the subject. But explain the examples later. Also, if you explain the examples LATER, you can use them to make some things you explained clear. Choice of materials and production methods would make more sense after "how it works" is explained.
    – If you want people to care about formulas, show them where each part of those formulas comes from. Also, what a change in parameters would mean to the spring.
    – Have someone check your English presentation for stuff like "gages" on 4:45.
    For the uploader of the video:
    1) By making this video, you violated the very copyright shown at the beginning. Cut that part if this video is illegal. Change the stupid copyright if it's legal.
    2) It would be good to know what's covered in the video and when. So, put timestamps in the description, one above another. For example:
    10:40 – Stresses in helical spring
    26:32 – Curvature effect
    Add more for what you consider important; before, after and in-between.
