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
I love the enthusiasm!

8:12 thought X would be 3/5 and Y would be 4/5 for your cos(theta)
i got confused too
Nice for Static’s and Structural analysis

That was his falt i think , i also realized this point
Can someone please recommend me more videos regarding the structural analysis of frames ??(Civil Engineering). I will be very thankful to you.
thank you very well explained and I fully understand this now
Awwwwdjyeah... clarity!
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.
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.
thank you, very clear and pinpoint
Sir i'm a bit confused as to why you didn't consider the reactions at fixed support C into the fbd?
why at the inclined beam we don't consider By and Bx at the opposite side?
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
The solution for this is the same with no hinge?
I feel making sections is a much less complicated way of solving for internal actions. However good video.
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
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.
goooood job❤
Thanks! 🥰
what's the ended value in moment ? (after 6.25)
0
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.
When's the part 2 coming?

There's also a link in the description.
Isn't this structure unstable? Just by inspection
Kinda yeah
The pins at the top make it go left and right
Waiting the bell thsks dear Prof
thankyouuu so muchh
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
