Wow……took statics 40 years ago in the Fall of 1984. You make it fun to learn!  

All young students are blessed to have a great teacher like you! God bless you……..

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."

what a Brillant and simple explanation thank you sir wow!!!!

Not all heroes wear capes. Jeff Hanson is one of them. Thank You G

[jaydean]

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

[Willifordwav]

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

[quinnpuffer]

Jeff Hanson you seriously have made learning so much fun and I hope you understand that you have really made a difference in the lives of the people who learn from you. I appreciate your videos so much. I'm actually having fun learning statics now

[نزارالمنجم]

hey just a moment this dude is actually making statics funny

[JamalsJournal]

8 × -7 is 56, not 42. Nice lecture, by the way. You really make everything easy to grasp.

[sergeantbarnes]

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

[Jschlick]

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

[SurprisePickle]

I love you jeff but I'm not crazy right? -7*8= -56 right?? I dont see anyone saying anything in the comments so I feel a little crazy

[Carbon-Aura]

He really meant it when he said he'd call a positional vector "How to get to Grandma's house, " for the rest of his videos

[OK-nsdm]

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 !

[hyundeokseo]

Sir you are saving a lot of engineering guys out there

[PlaysPlaystation]

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.

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

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.

[sathyaprakash]

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

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
