    Jeff, this is an incredibly well taught lesson. Thanks for helping me iron out some hang ups I had! “Multiply by two to get in, divide by two to get out”. THAT is the mental picture I needed. Thanks! Nice verse at the end too buddy.

      @ebi3141 9 дней назад

      Was thinking the same thing. I completed my degree 10 years ago, just needed a recap. 30 minutes seems long but what he managed to explain in that time would normally take a few 90 minute lectures.

    The charisma here makes learning material so much more interesting. No matter how interested people are in a subject, it's so much harder to learn when the lectures are dry and boring. I always come back here when I'm confused becuase the energy really helps make the information way more approachable.

    Thanks for doing this video Dr. Hanson! I’m beginning my studies for the FE Exam and I’ll admit that Mohr’s Circle used to seem like alchemy circles to me until I saw this video. Your explanations and clarity helped me significantly in understanding how this works!

    Mr Jeff, there was a slight error you made with regards to angle phi on your Mohr's Circle. You wrote down phi= 29.47 degrees instead of 29.74 degrees
