the best explanation on rigid bodies in 3d so far !!!

[colinmyers]

When I'm doing this in pen and over halfway through the video you go "let's change things up, we don't need this anymore" or "I'm gunna undo this", I cry a little bit

Professor Hanson, thank you for a solid explanation of a 3D equilibrium of a Rigid Body.

[jaydenogilvie]

this man obviously has a Phd in awesomeness

[sergeydidkovsky]

Many thanks to You, mr. Hanson. Stay healthy, greetings from Kiev!!!

[Zzzzzzzzz]

A really great teacher and a cheerful person in general.
Thank you doctor!👍

Dr. Hanson, I've been watching your videos since Spring Semester 2020 right as COVID hit and the lessons helped a lot. I have to take the class again as my university did not allow that credit to transfer. I am no expert here but I want to point out that by 2:20 in this video you violated one of your most important principles in summing the moments. I paused the video as soon as the problem was legible and worked it all the way through. Upon resuming play I was pleased to see we chose the same x-axis, that brings me this much closer to being a legend in this business. However, you and I did not choose the same y-axis. I chose the far-long edge as that eliminated the 500# weight and wheels A and C. Thus giving me an immediate answer for the force on wheel B. I will finish the video now and see your results. I'm assuming your answers look something like A = purple, B = Magna Carta, C = 1492 CE.

Edit: After watching the video and looking through the comments I realized I put wheel A along the far edge, like a 4 wheel cart missing a wheel. Dr. Hanson, I stand corrected. You should stick to your day job of talking about Statics and let the Fine Arts people do their thing.

My prof has used the cross product to solve problems such as these but I am unable to find any videos or resources on that exact method

[nolandavis]

im writing in pen and when u changed the axis, i cried and then proceeded to redraw the entire thing

[nolanhensley]

Shame on the one person that gave the dislike..

[JakebCortus]

could you also just find the equivalent force system of the known, than solve the rotation about the CB axis to get Az, then go from there?

[enriquepimentel]

If the cart can't move through the x-direction, why isn't there a reaction on the x-direction on all three of the wheels?

[Glorvox]

For the moment about the new Y-axis, should it be 628.57(24) instead of 628.57(12)? Since we moved the y-axis over. I'm still learning so maybe I missed something.

How is the Cz not causing a moment😢? "About the x axis"
