If you need a step-by-step on how to apply the method of virtual work for beam deflections, this video is a good place to start.

+Segurasegura Jorge no it isn't, castigliano has a lot of similar stuff going on, one might even say it builds on the Virtual Work method, but it is different. Just google it

Thank God for structurefree

This guys intros crack me up 😹

Just want to give a huge thanks for making these videos! You make many concepts so easy to understand. I really appreciate these videos!

Seriously love your videos. I'm not gonna lie, you've helped me a good deal on a couple of homeworks and tests

Hello Mr StructureFree, any chance you can do a video on Stiffness Matrix and Plastic Analysis? I understand this may not be your field but we have exams in January and we NEED you :'(

thank you very much! Very useful video!!

Could you do an example of this method using the Mohr's integral matrix?

why are we using real curvature M/EI??

Thanks for usefull videos 12:07 is it right I describe the M function as M = -10 ( 3- x) then 13:49 the rotation will -1/EI * integral { -1 * -10 (3-x)} from 0 to 3 = 45 ?

Why do you use 1KN/1KNm instead of simply 1N/1Nm that would simplify everything?

You are the best dude! I really like a joke at the beginning 😹😂😂

Isn't the virtual moment function 1KN.x - 3KNm? Did you apply a virtual unit moment when you were to apply a virtual unit load ( 8 min into the video)?

Do you have any videos that explain how to get the moment functions?

You the best, dude

thank you man good

Thank u sooooo much

why is the moment negative 30?

i dont know english well but i understand it and i can make my exam tomorrow :)

Can you tell me how do you find moment functions?

Why do you apply a moment at the end of the beam instead of a downwards 1 particular load? Would that be the same?

Nvm I've already seen the video again haha

Using the princple of virtual displacement with aprrox. with approximate virtual func. below determine the tip displacemen of the beam(&u=(x^2/L^2) &u= (X^3 / L^3) &u=(x^4 /L^4 ) AND &u= lnx /L^4 )

awesome

hello, how do you determine the moment of real loading is -30kNm. what i mean here is how do you know the moment is negative? sorry if i sound like a noob here :(

@structurefree

Fahmy Hamzany the negative moment depends on the internal sign convention used for the beam. in this example, i am looking at the beam from going left to right and positive internal moments cause compression at the top and tension at the bottom. Hope that helps.

okay now i get it. Thank you very much sir :)

shouldnt it be 3x-30=y ?

You...I like you

Virtual work and unit load method are same. Aren't they?????

What happens if the Force is somewhere in the middle of the beam? (i.e. not loaded at the end)

How do you find the “virtual moment”. This concept makes zero sense to me and I have no idea how you got the numbers that you got.

@carultch

Жыл бұрын

You arbitrarily assume a unit moment is applied at the location. How large the moment is, will ultimately cancel out of the equation, so to keep it simple, you assume it is 1 N-m.

Thanks! Awesome video!!! \(^_^)/ Do you have any videos on doing PVW by using equations instead of the graphical method with discontinuity in loads? I've tried doing that but I can't seem to fully understand how to apply the method of sections. Thanks in advance!
