Statics: Lesson 21 - Introduction to Moments rXF, Torque

awesome explanation of r vectors in your example. thx.

Keep up the great work

Jeff just found your series of Vids on Mech Engineering finally someone who KNOWS how to teach!,

can you not just do normal basic moment calculation for the last example?
when do i use the 3D position vector equation and when should i use normral moment.

I was worked up

All I did is sin(60)*24*100 to get -2078

Why do I get Dora the explorer kind of vibes so I can learn? It works, Sir you are the reason I passed. Thank you so much!!

Sir you are saving a lot of engineering guys out there

damn this guy is freakin good

Got my first Statics midterm today, this video helped me a lot, thanks❤

Nice

If you struggle with cross products there is a solver on the TI36x Pro it's under the 'vector' menu's 'math' option, it's a bit of work to enter it all in but it's a great double check.

7 * 8 is not -42

How do we multiple three vectors?

Hi the way i usually do this at work is just taking all different forces and "rotate" them until they are 90deg to the plane then do the cos of angle to determine the length. then i can do the moment equilibrium equasion. of course in extreme cases this can be quite a mess but usually its just a few forces. so i can draw a 2 d diagram, with all the forces being eather + or - the length

Good lesson 😌👍

You are the man! Thanks

Thank you so much, God bless

hey just a moment this dude is actually making statics funny

the intro had me dyiing LMAOO

hello, im on my final year mechanical engineering and i just understood the concept and how to calculate torque and moment using vectors. Thanks. Your videos are amazing !

Professor Hanson, thank for a classic analysis and introduction to Moments and Torque in mechanics one.

you mentioned you had another video that explains how to use ti-36 pro to solve the equations, just wondering what video that is?

Brilliant.

7x8=56, not 42. But i'm guilty of using a calculator 8=)

I appreciate your corny ass jokes they help me focus

thank you thank you thank you

I'm from the south, so I really appreciate your accent haha. I feel like my uncle is teaching me about statics.

Nice joke about moment!:)

thank youuuuu!!

That just a moment joke cracked me u!! I am ashamed of myself 😂😂😂

Dr. Hanson I may see one problem. When you did r2 you said the distance is 24 on the x. If this is a right triangle shouldn't "x distance" be different then your Hypothesis???
If the same then, then we have adj=24" opp=12(5)^(1/2)" and of course hypo = 24"

Great video but 7x8=56 not 42

I love your content. Its great for helping me get through statics with all the online courses this semester. also

p1: "What's torque?"
me: "Just a moment."
.....
p1: "How many moments you need?"
me: "Just a couple."

I'm having trouble understanding where the r2 comes into play.

"Dont wanna get ya all worked up there" LMAOO

For r x F can you use rFsin(theta) where theta is the angle between r and F?

Thank you! I understood the concepts.

Good and bad moments

the super intuitive definition of position vector which makes taking moments easy.

just review what I learned before during the lockdown, really helpful, fully appreciated

Very useful video.

I hope I can run into you someday and ask for an autograph, im your fan :)

I'm glad you are remaking this series! I am in my summer statics right now, except the hibbeler 5th edition seems to be one chapter ahead of what you are on or something because moments is chapter 3 now.

Good lesson - just one minor error : M = -22i + 54j + 74k (not 60k)

Wow 🤩
