Ahahaha "WHAT DOES THE BOX WEIGH?"

Suddenly i'm seeing a fox with a box going "FOO FOO CHOO FOOO FOO FOO CHOO!"

[youssofmasri]

how you make things looks so easy??!!! i have a static exam tomorrow, living on ur videos hahaha

[demonsagex]

YOU ARE THE BEST ENGINEERING PROFESSOR IN THE WORLD! <3

[manuboker]

Wonderful Statics lessons!! really taking the time to explain the problems along with a good sense of humor :))

[robpatterson]

I like you dude! Just reviewing stuff for fun and ran across your awesome video! Thanks for being cool.

So the location of the center of mass on the y-axis has no bearing on these cases? Does that only come into play after the object has started to tip?

[derinozyurt]

you are amazing i love you so much, you make everything seem so interesting and fun and love your jokes.

[jozefbroertje]

why do you take the normal force at the corner by the moment?

[Explixit]

What if a box is top heavy or bottom heavy? How do you model the moment it tips then?

[tommytran-nguyen]

Could you decide which of the first two cases is more likely to occur by comparing the two max forces of friction? and could you decide beween cases 3 and 4 by comparing the moments of the friction forces?

Dr thanks alot I done 52 problem now I am at 53 and so far if you give wieght I can tell you tipping force and slipping force or if you give me cofficient I can tell you angle of slipping so far,

[mariam]

I love the way you explain its make me repeat it again thank you now i understand it and the information still in my mind😁😁

[georgiaclifford]

ok, dumb question, but I got confused when he was finding the moment around point c, which corner did he declare as point c?

[georgesadler]

Professor Hanson, thank you for a fine explanation of Friction Slipping Tipping Problem. From taking Engineering Physics One many years ago, I am very familiar with these classic mechanics problems.

[ImranKhan-tuix]

I forgot to tell tip for friction problem
Always write Fs( friction force) in coefficient × normal like
👉 .5 ×N
For example two many forces are acting you Don't know any force this will help if you find normal you have fs if you find fs mean you have normal as well it helps when drawing FBD

[ImranKhan-tuix]

If u take sum of the vertical force ans is 54 but if you find vertical force by moment its 48.6 why ? Why?
Length 18, Wieght 54# vertical suport after 10ft man push horizontally from 1 side( no other force acting)

[scottcassady]

Your videos are excellent! My only comment is that on the top stack tipping, the force should have been 900#. I think you forgot to divide by the 0.5 in front of P. Of course, this just drives home the point you are making even more!

[rayzedd]

thank you, wish me luck on my statics exam😅

[ImranKhan-tuix]

Moment is more reliable then sum forces vertical sum of forces horizontal

[ImranKhan-tuix]

Dr my advice for students solve all problems in the book every problem is different and you will face same problems in real life
