my professor spent 2 hours of lecture explaining this, and I didn't understand it. This 20 minute video made everything clear. This is the power of literally just highlighting the equations that you use, and why you use them. Also, I asked him during office hours if there ever was a practical application for this, and he said no (:
The way you teach is amazing . I just love the way you created and solved different scenarios in a simple easy way, with logic and explanations, Please keep up the hard work...
Me i understood it in the russel hiller book when i just came across it first time and it was simple as cutting hot knife through butter i think the book (russel hiller) is a very very good book for statics and dynamics for have understood almost everything there is to know about statics without a drop of sweat....afterwards i come to your channel to watch and verify what have understood in the book 📖
Good work BUT.... as soon as you move the Force vector F, would it not change the original M vector? The original M vector owes its existance (magnitude and direction) to the POINT the resultant F vector passes through. No?
Do the resultant forces always act at point O? Is this arbitrary and for simplicity reasons? Could we technically place the resultant force line of action anywhere?
If we wanted the resultant moment around an arbitrary point D, the resultant moment would be different, but the resultant force would remain the same, correct?
Yes the resultant force can act at any point along the line of action that intersects point O (as it will not create any additional moment) but for simplicity we place it at the point O as we found the resultant moment around point O. And yes, if we are now interested in another arbitrary point, the resultant force will remain the same but the resultant moment will differ (as it is dependent on the location of the arbitrary point). Hope this helps :)
"so as we can see here our wrench, it sucks ass. not gonna lie here, it blows chunks." well said my friend, well said indeed.

Finally I understood this topic!!
Thank you for your wonderful explanation, it's really amazing.
Great explanation. Really clear.

Oh god, now I clearly understand thanks a lot!
This is where it gets tricky

@@ClaytonPettit it really does… thank you so much!!
Loved it!
Why is the parallel moment vector for the wrench able to shift up and down? Why are you allowed to move moment vectors like that?
Lol it's because it is a couple moment opps
