Shear force and bending moment diagram practice problem #3

This tutorial goes over how to draw the shear force diagram, bending moment diagram, and deflected shape of a simply supported beam with distributed load and some point loads that are oriented upwards.

TYPO: In the sum of forces in y calculation, the LHS is written as (120kN/m)(12m). I got a bit ahead of myself, it should be written as (10kN/m)(12m). I do the calculation as if the the right numbers are written, ie "(10kN/m)(12m)" so I end up finding the correct value for A=40kN. Sorry if that causes any confusion.

Thanks for watching, The Struggle Is REAL!

u miss wrote for summation of Fy...u wrote (120)(12)..when it should be (10)(12).... to get A

[andreslara]

One of the best explanations I have seen. Studying for my EIT one year after graduating with my ME degree.

[iyiolakomolafe]

you really helped me understand this concept. keep up the good wrk of motivating people to learn. God bless

[zehnazenia]

You explanations are 110% better than my professor...

[babakiani]

Thank you very much for the great content!

hey i was wondering why is the center of mass of the beam not considered when using moments to find the forces about point A and B

[greatpharoh]

Dude, who are you? These videos are incredible!

[tetliusakatsuki]

what if we got negative in A? i mean for example of others question

[thomasmetias]

When you calculated the Ma you wrote 8*12 at the the end.. where is force 8 which have is 12 m far from point a ?

How did u get the 6m morning n the summation of the moment calcs

[Dana__black]

Do you have any videos with triangular loads?

[greatpharoh]

Question: Can we technically show the bending moment diagram as almost one large curve rather than it looking like 4 different curves?

[meekbronsen]

hey what software are you using to write

[nuraddilah]

oh btw i think u made some slight mistake regarding on sfd graph where from the first +20 should be going to 0 instead of -20 because like u said in ur video, 60 going up 80 going down so it will be -20...

[sivaparansivakajan]

Hey, I think the bending moment diagram should be in negative part of the axis.

[v-niftytrickster]

". . . Or you could skip that work . . ."🤣

[maestroemman]

why did you times 10kN/m on 4m on shear fd

[thembietshuma]

i wish you can explain a little bit slower so l can understand more

The concept is correct but the way you skip too many steps of the problem is not recommended. Most of the professors required the students to fully express the problem in each section of the beam because not every beam is easy to do like this way.

why am I paying to study engineering in my college?
