When your previous Lesson 64 became unavailable and the error message said it was private, it scared me. I use your vids in my online statics course, so if they evaporated I'd have to adjust pretty rapidly. I was delighted to find that there is a new Lesson 64 to take its place. Evidently you just decided that the old version needed improvements. That's a sign of a real pro, BTW. Your channel and your Statics course are already wildly popular. You could just rest on your laurels. Instead, you are always looking to make it better. I appreciate that.
in the block A, shouldn't be a friction between the floor and the block A? then, mu would be dynamic in that case, because the block A moves a little bit, so there should be a friction force that oppose the movement of block A, isn't it? look for instance, in the surface between A and B, there is a friction force, either the block B is moving.
thinking again i agree with Jeff simply becos we r focussed on Block C indtead of Block B.So if Block b slides upwards thrn Fc must act downhill of the slope

at 10:40 he knew I didn't push pause lmaoooo! Guess ill pause for real this time then. lol
I hope Jeff knows how much we love him
Thank you for the videos, Sir Jeff! They're helpful, as always.
Wonderful Statics lessons!! really taking the time to explain the problems along with a good sense of humor :))
Really needed this for finals, thank you
Welcome back sir !! Awesome example.
in the block A, shouldn't be a friction between the floor and the block A? then, mu would be dynamic in that case, because the block A moves a little bit, so there should be a friction force that oppose the movement of block A, isn't it? look for instance, in the surface between A and B, there is a friction force, either the block B is moving.
Can you do more videos on dynamics??
u can visit my channel for dynamics!
Could P have a negative value so it slides down the ramp?
Just as I was looking for this video!
why is friction in the direction of the motion? why wouldnt it be opposite that direction.
Am I still in Statics? No. Did that make me less likely to click? Also no.
Why is fc upwards? Shouldn't it be the opposite since you said block b is slidding upwards?
The normal force Nc is what’s pushing B upwards, Fc (and Fa) are countering it, so they’re in the opposite downwards direction
thinking again i agree with Jeff simply becos we r focussed on Block C indtead of Block B.So if Block b slides upwards thrn Fc must act downhill of the slope
I took time off from watching this video to fear Denis 🇿🇲🤣
Hint: Annex Wifi
block b does what👀
If block B moves, then block A must also move.
