Mechanical Engineering: Ch 13: Virtual Work Applications (7 of 39) Completely Constraint Structure**

In this video I will find the reactionary force at point Bx of a completely constrained structure with 2-attached pivot point.

Next video in this series can be seen at:

Thank you. I'm broke otherwise I would have donated to your channel. Such a great teacher is hard to find in real life ! Only on virtual world they exist.

literally sir you are very noble! i pray to god for benefit of this great noble cause! you are doing excellent, elegant yet a great noble cause sir ! teachers like you are diamonds! thankyou for your efforts sir! i can't describe my gratitude to you in mere words! thank you very much!

Thank you professor. You made this subject more clear to me. One more subscriber.

Watched the video this morning. Same question came out in exam 😊😮.
Thanks you

Hello sir, you have made a mistake while multipleyinf F force with dy, there is a negatif sign before L.sin(teta).d(teta)

[NKShahariar]

hello sir, I have a question
Why are we ignoring the minus sign while er are pluggin in the value of dy?

I have a question about the method used in this video. Since the structure is completely constrained, and is not really moving in any direction, why is it valid to (arbitrarily) decide that the virtual displacement vector at point B should point to the right? Wouldn't it be equally valid to imagine it as pointing down, or in some other direction? And if we did so, wouldn't the calculated forces on the structure come out differently? Or did we treat it as pointing to the right because we wanted to know what force the structure will experience along the horizontal axis, and not the vertical axis?

Would it be possible to then find the value of theta at equilibrium?

[m.l.v.wijesiri]

why didn't you consider the negative sign of dy professor?
