Statics: Lesson 57 - Introduction to Internal Forces, M N V

[@khaledjarad5850]

God bless you Jeff wouldnt be making it through statics without you

[@dhruvik3503]

You deserve my university tuition

[@marcbrandonpoligrates7079]

I wont be surviving mechanical Engineering without you sir. this is far easier to understand than in my classes at present

[@RK-tr7wo]

You are so dedicated professor. Doing videos even at the middle of the night. Never seen a dedicated person like you.

[@umix1232]

Hey, Jeff. You should definitely mention your Patreon in your videos because I think a lot of people watching don't even know you got one and would love to contribute. I think you truly deserve something in return for saving all of our asses. Thanks, man!

[@humbertouquillasmartinez6301]

I am studying as engineer in Mexico and believe me when I say you professor have helped me a lot in succeed my test and homework's :)

[@marychristyllacson9128]

you saved my online class during the past few months and your saving me again. thank youuuu

[@georgesadler7830]

Professor Hanson, thank you for a positive introduction to Internal Forces M,N and V. This topic is very important for Mechanical and Civil Engineering students.

[@aphelelembatha2308]

"When you get left at Walmart how do you feel?".🤣....best explanation on KZbin

[@uwalakapaul7970]

Fr😂😂

[@lojaintarzi1861]

you've actually saved my life as a mechanical engineering student

[@abdulmoeiz2672]

Your playlist helped a lot in this pandemic. Thanks man!

[@Lexyvil]

Mickey Mouse whispering me about not forgetting M N V. So far it has worked. if only many more teachers could find fun mnemonics to help students retain information like that!

[@collinl40]

Studing for my senior level machine design class. Had to come back to the absolute GOAT for statics review.

[@jdsmith8282]

THANK YOU!! You taught me a whole week's worth of classes in the span of 20 minutes. This video was PERFECT review for my statics test

[@kristiansapien8407]

This was actually fun to watch, love it.

[@danielleshaffer620]

Hitting up that patreon for sure! Wish I had found you at the beginning of this semester lol. Watching your videos before starting a chapter really accelerates the learning process. Thank you!

[@davidordonez8964]

Best video on KZbin thanks! God bless you and keep using you! 🙏🏻

[@timmy7981]

Sending love from Nigeria 🇳🇬 thanks man❤️

[@ryanf223]

THANK YOU JEFF. I just passed my Civil FE one year post-graduation. Your videos really helped me review and remember everything from college. Have a fantastic day

[@gijsvanderklink2346]

Thank you Mr. Hanson. I'm watching this video all the way from The Netherlands and you really help me out.

[@thevladdo]

Thank you so much Dr. Hansen. These chapters have such bombastic names but they wind up being so simple.

[@leta3713]

You are absolutely fantastic, Jeff! I preferred checking out your videos to reading my textbook. You put the whole thing simply and in a convenient way to grasp.

[@whimseyy]

Salute to you Sir! You are currently saving my college life👏👏

[@SunMapping]

Here in the midwest, we have a store called Hy-Vee for groceries. So I just say, "If you got LEFT at Hy-VEE, you would feel down", since the "VEE" just sounds like "V" :)

[@anyalawrie352]

I literally have an exam in an hour and realized that I have no clue what’s happening in this section, this just

[@tructre413]

Love your mnemonics to remember terms better, so dedicated ! ^^

[@kareemG00dmann]

I'm an electrical engineering student but I've structure course this term I don't know why and I didn't understand the sign convection from college at all, but you made it so easy so thank you very much for simplifying the information!

[@BloodCatters]

I have finished my bachelor's thanks to you. Now I am coming back to the same video for my master's :D

[@arasrevend1529]

Engineering steden from Sweden, bless you soul Jeff.

[@unnamedracer9757]

this man is why I'm passing statics

[@julianpamintuan2762]

Greetings all the way here from the Philippines. Thank you for this.

[@laurarivera1855]

love the sound effects lol. Such a helpful video, thank you!

[@angelfrance1595]

I'll give you my entire tuition if I can just for making this fun to learn 😁

[@luxeternity]

Mr.Hanson ...I would say it would be good to see if you do a main topic such as this then you divided it into several calculation involving different shape such as triangle, right angle triangle , circle etc. We could see if there's any extra calculation when trying to calculate it and also different scenario like a triangle shape but it has extra length on the beam like in this video

[@ezraclark1793]

Thank You so much for these videos, they help a lot!

[@tinekese5025]

iv got a test in two days so this helps a lot. You have my thanks.

[@saidsafadi-s2d]

I have a test this week your saving my asss

[@jeffersonrondina8247]

"Don't get left on wallmart." HAHAHA Thanks prof!

[@berkayeser8266]

I'm from Turkey and I'm studying Mechanical Engineering in Turkey at a university. You Mr. Jeff Hanson are the most live and instructive lecturer I have ever seen. I hope you will more successful your life and about your KZbin channel.

[@theiqboy3869]

God bless you dr hanson

[@maryambanoosayyadi2575]

You just save me every time man❤️

[@evangitetaylor1435]

Thank you so much Sir . God bless you

[@MrZeyad008]

The value of the moments are the same regardless of whichever side of the beam you pick after cutting the beam but you will get a different direction (counterclockwise, clockwise,..) so when asked to express the direction of the moment at a point, which direction do we write ?

[@windyjay4627]

I have a very very good feeling that if it is negative, still write it as clockwise. If positive, then counterclockwise. I think when analyzing the beam you don't use the standard directions as the values of each side of the beam wont be equal (opposite signs (which makes sense since you are analyzing opposite sides of a point on a beam) ), hence the new direction rules. But when writing the final answer, you return back to using the conventional direction rules.

[@Tristan02539]

I literally stopped going to my statics lectures and just started watching your videos instead. I wish I could give you the $650 I spent for this class.

[@sarahchacon749]

I love this dude. GOD bless!

[@5ajidMukhar1]

Fabulous Explanation ❤

[@YehanDeSilva-x1o]

When you get negative values for v does that mean it’s acting on the opposite direction? Are the directions the same even if you choose to go from the left/right?

[@starfallgaming4849]

Just to clarify, N is negative here because there's no force along it's direction?

[@akiffftrn]

thank u jeff for all

[@Jaguarlul]

Thank you!

[@Chickwan]

Jeff for president

[@MechEngineer37]

The burrito would be negative, but it's a positive for me.

[@lovescrubs99]

Some weeks I spend more time with Jeff Hanson than I do with my family.

[@domnoeffect6423]

Could someone explain why M and 200 is negative at 12:31? Much appreciated

[@adamgulamhusein8768]

M is negative because it is going clockwise. By convention, this is typically negative. 200 is negative for the same reason.

[@mathewndimila9273]

[@armandl9021]

Thank you Jeff appreciate the help !

[@bridgeconstruction_irwansyah]

be healthy Jeff.

[@librokubic6556]

You are a lifesaver!

[@fuhrerkozhin5717]

You are true legend🤜🤛

[@kimandreasimon586]

you're the best!!!!!!

thank you so much, i learned it finally

[@stevenbutcher4565]

Great video!

[@nagimka986]

Goat, love from eastern eu

[@carmenjmz5038]

up stuff = down stuff didn't work for me and my problem. It looks exactly like yours but with an additional triangle distributed load. Is that why it's not working?

[@emmanuelheri3457]

Thank you

[@amirulhaziq3776]

deserves a sub

[@zaydantulay9680]

best teacher

[@NyashaJ-tp4uv]

thank you Jeff , i don't like the inches much but still all good haha

[@foxg3293]

It's just an amazing way to illustrate lessons, thanks so much teacher , but here is only thing that you should think about, if you are Muslim that's great if not , think about joining islam , if you get in , there are amazing rewards going to be wating for you at another life cause you are a professional teacher , thanks

[@xXSLMXx5180]

Can someone explain why for when he was finding Ma for the -200 he didn't multiple by a distance

[@9LimaAlpha7]

how did u identify the directions of the moments after you cut the beam??

[@only-legitness]

thank you sir

[@tructre413]

why at 12:01 and 12:26 that V is in negative sign and M and 200 all have a negative sign ?

[@احمدمحمود-ب2ث5ع]

thanks from Egypt 😉

[@jpna8223]

Shouldn't the shear forces be same magnitude but different signs/ direction?

[@sevgipnar5261]

yes ı didn't understand that part too

[@justinwong8676]

how can i not uds this from my lecturer? Thanks, Professor Jeff

[@masondebeer5580]

thank you!

[@angeloumagboo8848]

thank youuuu!!

[@WJHou-hz2de]

if anyone here would love to explain it for me, why is V negative at 12:09 and why is it -M-200 at 12:36 😢 I don really get it the sign convention is confusing

[@balajihariharan7175]

there is a upward positive force By, so to balance it our V has to be equal and negative. And M is in the clockwise direction, clockwise moment is negative

[@gaganahuja26]

3:25 Here's the replay button for the best moment 😁

[@yungneutron164]

big ups buddyguy

[@leogobeil301]

tHIS DUDE IS gOD.

[@therealadumboi]

finally i can learn about forces without being confused by just watching a video about an egg and a fast car

[@silverbackdungeongorilla4315]

Adamsin jeff reis

[@LucreziaPignatti]

why is Ax=0 ?

[@uwalakapaul7970]

No other horizontal force Following Summation of horizontal forces = 0

[@muhammadowaisquarni5171]

how did he got the value of Ay?

[@jackphilibotte2844]

What changes Ay to 136.8 rather that it also being 113.2, I can solve for B but I don't know what is being done to it to make A, he says -250 but when I look I get minus 225, and I don't know where that would come form. 10:01 thanks

[@_AnUnoriginal_]

It's the equilibrium for fy, so the equation is Ay + By - 100 - 150 = 0 since those are all the variable for fy. From there, you just move the equation to Ay = 250 - By. And you should get Ay

[@_AnUnoriginal_]

Hope it helps.

[@jeanmartin2209]

we must have M N and V oh my God haha i dont know why i repeat with the same way that you tell thanks for you Mr

[@MasatoXci]

this helped me fr lol 5:06

[@muhammadnurfarhan8453]

Thanks sirrrr

[@ciciwood8767]

can someone please explain how he found the 0.5 for that tiny distance between the cut?

[@talhamalik8989]

in question,he asked to cut section at at 7' so remaining part is 0.5'

[@altheanolasco8371]

why is it (4.5) in the moment A in the concentrated force

[@lucastadesse2678]

4.5 is the distance between A and the concentrated force

[@gageiannitelli6994]

16:55 you really sounded like fred from scooby doo

[@evelinageorge2997]

Sir why did you take negative M there 😔

[@فيظلالرحمن-ح2ه]

nice

[@chelymercader8347]

that mickey mouse voice tho HAHHAHA

[@9LimaAlpha7]

10:25 why did u cut the beam in hafl?

[@camhowden1445]

I think he cut it at the 7ft line. Around 7:00 he explained that he'll be cutting the beam and choosing a side like the method of sections. That's also why we need the positive sign conventions depending on which side we choose. Hope this helped!

[@Mac-ih7rb]

who is disliking all of these videos show yourself cowards

[@thed00t76]

Take my uni tuition

[@osmanjantalipjan5608]

u are so cute prof. i loved you teaching method

[@parasamin5550]

Can someone help me understand why Ax = 0? Thanks!

[@hussam-ym]

Hey, if you try to construct an equilibrium equation in the x direction ( Fx), you will only find Ax there, which means Ax=0, in other words there is no other forces in the x direction that Ax would balance and so there is no x-component for A.

[@hussam-ym]

Also, the reaction at B does not have an x component because it is a roller, refer back to Prof Hanson's video on supports and the reaction forces they give. So that leaves us with only Ax in the x direction, and due to equilibrium sum of forces in the x=0, Ax=0.
