Your steps to solve the problems are very simple and clear. You don’t assume that people know already something. It is very important in teaching because student like me always need some refresher. Thanks for your help
The 35 comes from solving for the sum of moments at A to get By. The 3 forces producing a moment at A are: 1. The 25 (I’ll assume N for convenience) downward force on the beam 2. The 50 N downward force on the beam 3. And lastly, By Taking the moment of each of those (M=Fd) we get: 1. -25N • 1m (since it is 1 meter away from A horizontally) 2. -50N • 3m 3. +By • 5m Adding them up: 0 = - (25N•1m) - (50N•3m) + (By•5m) And solving algebraically for By gets 35.
broo you're everything a civil engineering student could ever need!😔🔥
Just flunked a statics test, thanks for having made this video, it's helping me figure out where I went wrong. Cheers :)

this!
I just spent an entire day trying to understand this and u made it possible in 20 min❤❤🎉thanks😊
Great stuff, Dr. Clayton
quite helpful indeed....am out of the bushes now
Thank you
I really appreciate, so very easy to understand
Thank you sir this is amazing!
great video thanks!!
Appreciate that!
God bless you man
well understood. thanks
Sir rollers I think must prevent rotation but it says it allows,can you explain it to me?
where did you get 35 from?

The 3 forces producing a moment at A are:

3. And lastly, By
Taking the moment of each of those (M=Fd) we get:
1. -25N • 1m (since it is 1 meter away from A horizontally)
2. -50N • 3m
3. +By • 5m
Adding them up:
0 = - (25N•1m) - (50N•3m) + (By•5m)
And solving algebraically for By gets 35.
thank you
I love you
