Frame Analysis Example 2 (Part 1) - Shear and Moment Diagrams - Structural Analysis

[@Spazzsticks]

My fave thing about you is your carefree,chill and relaxed attitude towards complicated engineering topics and the way you break them down as if these things are just some simple arithmetics. I can watch you all day man! Imho you are the best youtouber in this category!

[@falooo7]

you invested good time in these videos so if you could break it down more and slower your explanation so the new learners can catch up then you will reach to higher number of view for your videos, and for your writing try and write in large font. please accept my tips cause it will make your videos perfect

[@drewbee24]

sorry im having trouble understanding the vertical components. I get that they should sum to equal 80 but im confused how you got the 25 on the left and 55 on the right. I keep trying moment stuff but im not looking at this correctly. thanks

[@dr.abbasalwarafi1576]

I have the same question

[@dr.abbasalwarafi1576]

I have trouble too in calculating vertical loads..it is distributed loads, should it be 40 k and 40 k in each support?

[@cchanielmendoza7649]

Is it just me or doing calculation is like drama unfolding like one of those reality tv shows. Love ur video's

[@structurefree]

It's a K-drama. Lots of triangles.

[@kenyapascascio2487]

How did you find the vertical reactions at the supports? Which joint did you do a sum of moments about?

[@TheLevidance]

Best engineering vids on the internet here

[@jora30709]

Maaaan you explain at least 300 times better than my stupid book and professor together.

l0l u make it fun .. hopefully i pass statics with ur help! and countinue my adventure on my mechanical engineering uni

[@estherchua5428]

Hi! Could you explain the rationale behind making the bending moment, shear force and axial force *equal and opposite* for the adjacent member? e.g. transferring the loads from the vertical member to the joint. Thank you!

[@biswaacharya8689]

this guy is good

[@manojshikhar4554]

which software and device you use for making the videos.

[@hebunmehmetsirinuyar1733]

Maaan I love your Ganster speach style ahah Thanks You DA My MAAAAN

[@edwardarakelian8315]

I just wish you could have started from finding the reactions. but thanks again for all your videos..

[@edwardarakelian8315]

ah never mind. I'm just too stressed abt tomorrows exam. a simple moment around A or B helped. hahah

[@parthsharma7781]

thanks man, your videos are very helpful. I just wanted to know what if there is an internal hinge at one of the supports, let's say point B is an internal hinge.

[@mikexbox1]

BAAAMMMMM! Saved to my favourites!

[@shunturigovender5117]

hi im not getting the vertical reactions . because Ay = - By and if you solve for member B-C By + 2(40) + Cy=0 and sum the moments about C to get 2x40x40/2 + By(40) you get By= - 40 . i dont know what i am doing wrong

[@shunturigovender5117]

ok never mind i figured it out . you do not use that method you just calculate the moment about the supports

[@shunturigovender5117]

thanks :)

[@rodolfovaldez4169]

would yo explain that to me I am still getting By = 40

[@davidxguitar]

Vids hilarious bro. ❤

[@juanantoniobustindui5456]

Hi, excuse me, what is the program that you use for your presentations?

[@sharon8008]

I failed my midterm cuz I was completely lost. This makes total sense! Wish I would of found this earlier. However, I am lost at how you got the 5K for Cx....do I add up all the x forces or just at the joints from Bx and the internal force on Cx?

[@structurefree]

Yes, you typically sum all the forces acting on the free body diagram

[@ikjoseph9455]

Pls there's a question related to that that I would like you to explain to me please... thanks for that one...how can I contact you?

[@zeleniawolfe]

Can you please make an example video for portal frame that has different leg height? (Idk how you called them, english is not my friat language 😅) and also please plase make a video about two and three hinged parabolic arch? I got 3 assignments. I already finish one thanks a lot for your great videos! It really help me since i can't understand any of my professor explanation in class! Please help me, thank you!

[@zeleniawolfe]

[@iminsideyourwalls9432]

8:40 why isnt it -55??? shouldn't it be 25-80?i dont understand

[@veryfriendlyok]

Difference between roller and pin? I know roller only has one reaction, pin two, but in a real example? do they do that bc it’s an indetermined equation? I’m not an engineer major I took a few classes long ago in an architecture class, I’m just curious, anyone can help me? thanks

[@mariellachica8788]

10:00 why you did not include the load on beam to sum up for moment?

[@0-H.H-0]

Hi sir, can u plz explane how did u get horizontal force of 45 and reaction in a = 25 and D=65, tanx alot.

[@mohannadsawaifh]

1- look at the quastion at first you have 4 forces 10+20+10+5=45 this is the H.force for pin 2- for D=55 not 65 as you write and we find from - sum Fy=0 >> >> 2*40-25-Dy=0 *Dy=55

[@DongskiTeeVi]

mohannad sawa How did he get the vertical force at A which is 25 kips?

[@mohannadsawaifh]

DJ7thnz take the moment at D=0 and by eq. and forces .. contiue the solution .. then get value of A

[@theovolz3073]

Thanks Mohannad!

[@21leowheeler]

just wanna know why the vertical force isnt split in half on both supports, i found that slightly confusing.

[@structurefree]

The lateral loads cause compression on the right vertical member and tension on the left. If only the distributed load were applied then the two vertical reactions would be equal.

[@21leowheeler]

thanks alot man i kinda figured it out by doing sum of moment on the left support its amazing how clear the head becomes after a shower , in the morning its just like whaat :P thanks for the quick reply and the awesome videos.

[@ahmadelshantaf9675]

Thank you so much sir I salute you

[@galibxpress7580]

Why I use 15k in BC member B side in left direction?

[@renzobuizon3470]

Question: if there is a concentrated load at the roller support how will i include it

[@renzobuizon3470]

*horizontal

[@CampTutor-j3k]

thanks alot sir

[@martingillies1]

Why can't you be Scottish and do this in kN and m :( thanks anyway haha!

[@structurefree]

I'll put a frame analysis problem with SI units on my to do list.

[@MK2EA]

no not Scottish please a Londoner is fine

[@oliverwatson2768]

Anything not American would be fine... lol, but it's the same concept regardless of units.Easy to carry over

[@dixvlog9549]

i want to see how you solved a fixed support with non uniform varying load with rigid frames

[@ssajid40]

what if its a 3 jointed frame?

[@Wanjox]

I dont think the vertical forces are correct. If you take vertical equilibrium(sum of forces in y) they dont equal 0

[@structurefree]

Willo Wanjox 25k + 55k = 2k/ft * 40 ft

[@liliankabelle6943]

Thank you!!

[@liliankabelle6943]

Thanks!!

[@MomochiZab]

at joint c there is an internal axial force of 15k and external 5k, how does this become 10k internal shear force?

[@thenoobersaur]

super useful thanks

[@abusayeed3386]

Awesome

[@fayrafarinna5895]

how were you able to get 25 on ay and 55 on dy ??? by just doing it in your headdddd help me pleaseee

[@asaggu1173]

Taking moment on one joint! Example if u take moment at A= 20k(10 f) + 10 k(10) -2(40f)(20f) +5(20) +10(10) +20Dy. Should all end up DY = 55. Take vertical distances for all except the distributed load

[@misshollywood2356]

wouldn't the moment about A be...-20(10')-10(20')-80(20')+5(20')+10(10')+Dy(40')=0... Dy=45 :'(... i cant figure out why i'm not correct... the distance between 10k and A is 20' not 10'..... and the distance between Dy and A is 40' not 20' because it has to be the horizontal distance...PLEASE HELP ME!!! :'(

5:30 you wasted 2 min doing something useless you can just put the force 10k in any one of the members and adjust the reaction of the joint C
