How are there only 400 likes to these videos ? ? ? Excellent animations coupled with clear explanations. Rather than having completed equations just appear on the screen, I've discovered that graphics, animations, and equations need to be written out while they are being explained in order to help one grasp the meaning. This is one reason why it was so much easier to sit in class and go through a lecture with the teacher writing out steps on the board (preferably chalk, for some reason), instead of today's presentation of: Boom! completed solution! I think your mind needs the journey of hearing concepts, expecting an equation (chart, diagram, etc.) and then witnessing that fuzzy concept become solidified. I also really like the color differences. Though brief and not a complete replacement for the book and full lectures, they have clarified much of the material I'm going through. Can't say enough good stuff about these videos. I hope he does more ! ! !
5:48 why is the red line negative for sigma Ma? I thought the force trying to push the body counter clockwise should be positive? Edit: NVM, i figured it out. I imagined drawing a wall at the point of reference and assert the +/- sign in accordingly.
4, the "vertical" leg divided by 5, the hypotenuse, = the cosine of F3(from the vertical axis). So the vertical component of F3 is 4/5 of F3. My prof has been emphasizing to use measurements when available instead of angles. The alternative would have been to calculate the angle (arccosine of 4/5) then using that angle in the calculation of components of F3.

Great for statics review after more than a few years.
truly incredible videos and clear explanations. thank you for sharing such knowledge with the world.
Absolutely amazing video that helped me understand in 15 mins what I've been struggling with for hours. Thank you very much!
This channel is amazing, keep up the great work!

consise and clear explaining, cheers for this good work!
This is an amazing explanation
fantastic presentation of info really class
explained very well

The last diagram how did you get that x component and y component of F3
