This is part 1 of an example showing how to calculate the deflection of a cantilever beam. The solution uses integration to calculate an expression for deflection along the length of the beam.
You're doing a magnifiecent job I"ll be grateful and most of the students across the world will feel grateful if u upload some videoes of reinforced concrete deaign because there is no standrd book to understand the concepts of design of beams slabs etc specifically in india
hello mr. purdue..could u please make or guide me if u have one on a video dealing with a cantilever beam that has a udl. and instead of using numbers, could we just use formula such as wl/2. it would be much appreciated =]
What if I consider a beam which say bimetallic? The layer with load applied is copper and the supporting beam is of spring steel,how will we find the deflection?
@diflection1 OK ...i will try my best to explain this. i have a udl with a rigid support and a free end ( i think it is called a cantilever) and i am supposed to find the maximum slope and maximum deflection. it doesnt have any numerical values so where you would have a number for the weight, you would just put 'W' and the length is sometimes X or L. now this is what confuses me...sometimes my teachers uses L and derives a formula and sometimes he uses X. also, i donot understand the concept of
Sir, could you please explain the concept of stress function in the theory of elasticity ...and also the so called Airy's stress function which is so popularly used in theory of elasticity
Hello,sir. I am doing my physics course work now. I am upper six. My title of investigation is Cantilever Beam. If you can give me some good advices that is better. And I cannot understand the last equation which is -W/(6EI)×(36x²-3³). If you put X=2 in the equation, it doesn't work anymore.
I'm stuck on calculating the bending moment of a cantilever. The force is applied at the end of the beam at a 30 degree angle from the horizontal. According to a part of the solution, the Moment due to mass of beam: M = (0.5)(mg)(L). I don't know where they got the 0.5 from. I thought the mass moment is just M = mgL. Why is it divided by half?
bhai Hozintal force is mgcos30..which adjusted accordingly with fx summation=0 So Vertical force moment is taken about a section =mgsin30=0.5mg..for moment multiples with variable distance x..according to the cantilever

@diflection1 his free body diagrams. so could you give me a step by step guide as to the free body diagram of this problem so that i can derivive the correct equations to solve the problem.
easy does it javier! Concave up and concave down are popular terminologies, and sign mistake is hardly a mistake- especially 10^-6, one could easily find that mistake when the computation is abnormally small- IF YOUR NOT SMART...(as I suspect you are not) keep your mouth shut and watch more PurdueMET videos!
@hjstein314 - So how about he pays attention to what he's doing. He's an associate professor trying to HELP people understand things but not accurately depicting the problems. This isn't the only video he does it in, try watching his other one's where he does the same thing. Once is a mistake, multiple times is not paying attention. He's a confusing instructor for sure.
purdueMET, need you to pay more attention to what you are doing. When you first write the answer for I it is 10^6, but when you "save" it at the top of the board you use 10^-6 and don't correct yourself totally ignoring that you changed the sign. Also please work on your word choices...concave up? concave down? How about convex and concave.
You must be one of the best teacher...Thank you.
Thanx a lot, tomorrow is my exam and I watched about 5 videos of urs, u've made it so much easier. Thanx again
Thank You! You have done more than you can know
After long time i have seen a good professsor, he is one of the best citizen also....
best teacher on youtube
I am studying at CityUniversity of Hong Kong, and i would like to give you and your videos credits for me performing good in my examinations.
Where are such profs in INDIA's reputed colleges!!! Loved the way you explain :D

Thanks you! I study such subjects in my university. Great video! THANKS A LOT!
I subscribe for your video!
@diflection1 I'm glad the videos are helpful.
great work!
Tahnks from Brazil!!! very nice!!!
the smiley face is what dad taught me during my undergrad studies :)
it should be 10^-6 He just forgot the - sign.......excellent advice about the units! makes a good argument to pay close attention to your units
my teacher doesn't taughts me like this. Thanks, now i got something for Final :D

could you do a slimier problem using the delta formula 5/385.... rather than integration.
You Are GOD!
THANK YOU!!!
Dear profesor could you be so kind as to upload a example using moment area method for deflection?
Hi, Why did I have a positive 10^6 coefficient as answer and then at the top you wrote 10^-6?
thanks
Correct value is 10^-6

good

What the hell is a convex beam. People are here to learn about how to do calculations not non existing convex beams.
purdueMET, need you to pay more attention to what you are doing.

Have you EVER drove a nail...I doubt it.
