my professor spends 50 minutes yapping in a thick romanian accent while you explain it succinctly in 11 minutes. Thankyou

I'm taking Statics right now, and honestly Jeff (Dr. Hanson?) you're a better teacher than my actual teacher.

[georgesadler]

DR. Hanson, this is great explanation of Equivalent Systems and its impact on mechanics. I am currently using Vector Mechanics for Engineers by Ferdinand P. Beer and E. Russell Johnson, Jr, Fourth Edition., 1984.

I'm currently taking a five weeks online statics course and you are one of the few ways I'm getting thru it

[joshuaartuza]

Sir you are a fun teacher! You just pointed out and explained most of the mistakes and questions that I struggle to understand. Thank you so much! God bless!

Main point to remember here is the Point of Interest (POI). On this problem it is all about point A. ALSO at 3:15 the Doctor explains it very well about "Forces and Moments". Knock out the forces but not the moment. If you notice he didn't use the 300# force for moment because it would be 300#(0). I am thinking Fy should equal -600#.

It is unclear to me how clockwise and counterclockwise work. What is confusing me is the fact that the sum of X is negative and pointing counterclockwise. The magnitude sum, however, is also counterclockwise, but it is positive. Could you please explain? Thanks

If it isn't everyone favorite Texan

[balajihariharan]

how does the 200 kip force rotates A clockwise? Isnt it anti clockwise? Pls help

[onaopewapo]

Thanks Dr Jeff. Doesn't the 200kips force rotate it anticlockwise?

Does anyone know a source where we can practice questions like this? I no longer have access to the learning portal used by the school where I took statics and I'm taking mechanics of materials and dynamics this semester. I'd like to brush up as much as possible!
