How would you analyse the support reactions when the A and D pins are not on the same y displacement, ie D is positioned higher than A. One of my civil engineering assignment question questions is super similar to this one only with the problem i just mentioned.
I have one query, at the start of video while solving horizontal forces you took Dx as 6.667 pointing left but when solved for Bx you got -6.667 answer and you wrote is towards right rather than towards left ! Kindly explain..
In 2-d, if you cut something out of your structure joint, member, portion of a member, etc. there are three equilibrium equations that you can use per cut out.

is that for the summation of forces along horizontal at AB? that is because theta is with respect to y-axis. If you have a right triangle with an angle theta with respect to x-axis and you draw a line perpendicular to the hypotenuse, the measurement of the angle between the y-axis and the line perpendicular to the hypotenuse is equal to theta.
Such fun I had watching your videos. You explain with clarity and a midas touch
(14:11) I think -1.333 cos theta should've been 4/5 in this case, and 6.556 sin theta be 3/5
Nice for Static’s and Structural analysis
8:12 thought X would be 3/5 and Y would be 4/5 for your cos(theta)
i got confused too
I love the enthusiasm!

Can someone please recommend me more videos regarding the structural analysis of frames ??(Civil Engineering). I will be very thankful to you.

That was his falt i think , i also realized this point
thank you very well explained and I fully understand this now
Awwwwdjyeah... clarity!
thank you, very clear and pinpoint
How do you analyze how many equations will be set per body diagram?
In 2-d, if you cut something out of your structure joint, member, portion of a member, etc. there are three equilibrium equations that you can use per cut out.
Sir i'm a bit confused as to why you didn't consider the reactions at fixed support C into the fbd?
Hey structure free how come u didn’t consider the distributed load when u was looking for your VA NA at joint A?
It's because the cut is just before the distributed load and we are isolating the joint.
@@structurefree thank you
I feel making sections is a much less complicated way of solving for internal actions. However good video.
why at the inclined beam we don't consider By and Bx at the opposite side?
Could you let me know which program you use while making your drawings in these videos? By the way the videos are perfect!
lately i've been using microsoft whiteboard and onenote.
goooood job❤
Thanks! 🥰
thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you
Waiting the bell thsks dear Prof
The solution for this is the same with no hinge?
hello, why on summation of forces X, use sin theta? should it be cos theta?
is that for the summation of forces along horizontal at AB? that is because theta is with respect to y-axis. If you have a right triangle with an angle theta with respect to x-axis and you draw a line perpendicular to the hypotenuse, the measurement of the angle between the y-axis and the line perpendicular to the hypotenuse is equal to theta.
what's the ended value in moment ? (after 6.25)
0
thankyouuu so muchh
Why did you assume Dx direction to right direction?why not assume it as opposite direction?
I usually assume my sorry reactions are in the globally positive coordinate direction. Although, you can guess whichever way that you want.
Isn't this structure unstable? Just by inspection
Kinda yeah
The pins at the top make it go left and right
When's the part 2 coming?

There's also a link in the description.
ur amazing
i like you man add me on club penguin
I like you too, but I don't even know what club penguin is... I'm more club batman.
Not very comprehensive
