    Yup, he knows his stuff!

    OK so after over analyzing number 13, LOL does this look right? I just want to make sure I'm on the right path.

    Joe you did an excellent job on #13. You are getting it.

    Only problem is check your feet to meter conversion. There are 3.2808 feet per meter and 0.3048 meters per foot. So close.

    Good job Brad! :tu:

    Joe keep up the good work. I just graduated with a BSEE in May. I went back after being out of high school 14 years. You can do it!

    On second thought, I'm not sure if those electrical engineers can be trusted anyway. Bunch of used car salesman they are. :evilgrin:

    Great job to both of you!

    I graduated with a bachelors degree from a 4 year program in business and I have 0 idea what is happening in a few of those pictures.

    Joe, one more thing and I got to go to a meeting. I suggest you get a straight edge. Like a plastic triangle. If you notice all my lines are straight. Calculations look more professional and neat when you use a straight edge for things. That will impress whoever is looking at them including your teaching and also make it easier for you to follow as you are going. Just my 2 cents.

    I'd do it this way.

    600 rev 1 min 6.283 rad
    1 min 60 sec 1 rev

    Should come out to 62.8 rad/s.

    It looks like you started to do it that way but changed your mind.

    I think writing 600 RPM as 600 rev/1 min makes it easier to see how to convert to radians per seconds. On your attempt you had seconds in the numerator which would have made it impossible to get rad/s which has seconds in the denominator. The same applied to radians. You had your conversion in the denominator and need it in the numerator.

    Joe,

    I'm 15 years removed from college now. Phillip just finished so he is going to be up on this stuff more as you go. Plus he is just smarter than I am. :lol:

    I'll help as much as I can.
