Sir excellent ,I have tried many you tube channels like gate academy and many others but the way you summarize all things in one short video is absolutely incredible Hats off for you You have cleared my all doubts related to this topic
Superb sir I was forced to stop and comment when you started explaining through example of tug of war. I respect your dedication to explain concept thoroughly.
Sir im still confusing about 2 method in solve truss problem, the first method is joint method, in this method we are assuming the force is working on the joint because of that as we know about action reaction, the force which is work on the member have opposite direction with force that work on the joint When we use the section method how we assum about the force or where parts does the force work in joint or in member because when we want to calculate equilibrium state we usually isolate one stuff that force work on it
A few questions. in Moment of c at the end you are showing a vertical force in the counter clockwise position as negative. Why is that? In class we learned counter clockwise is positive. Also I feel like you made mistakes with the vertical equilibrium equation. You flipped the positive and negative forces when you were solving for GC. Why is that?
Sign conventions defined by us, hence It is not going to change overall sense of your entire equation. if I choose CCW is negative and CW +ve, it will also give same final result. actually if you will change sign of one term as per your convention, you will also change sign of other term. SO eventually it is just changing sign of all the terms in teh equation. Therefore, final result will not change, and the sign of final answer will define sense ...for example I choose CCW -ve and if my final answer is +ve I will say that my answer is of CW sense. Similarly flipping sign is okay a someone may consider upward forces are negative and vice versa. sign convention will not affect final answer. Moreover, I will be able to answer more precisely if you will indicate time instance,

Hats off for you
You have cleared my all doubts related to this topic
Thanks, that the first time I have seen someone explain why you ONLY have to use the cut truss because they have to be treated as EXTERNAL forces!

Wao, clean work! how i have been stranded with this topic
Glad it was helpful!
U deserve to be subscribed ❤️ you’re the only channel who explain clearly
Thank you
Very nice explanation Ashish ji.....
very good presentation and very Good Handwriting
sir
Thank u sir 😃😀
Excellent work
In point c Sir, why don’t you resultant FBC in forms of angle 60 like FGCsin60.
Super sir ....I watched this video my all doubt is destroyed by this video and ur explanation ...thank u sir.....

sir, WHy have u not taken Ax?
Can you specify time instance

Currently in a class..I WILL ANS YOUR QUERIES SOON

Thank you
@@ashishpurohit9138 OK sir
How to calculate the angle sir?
Angles are simply find using trignometry aspects.
@@ashishpurohit9138 using tan inverse?
how did you get 0.67 on the FGC
can you please indicate time instance
Good. But teach in single paper.. Don't use bit bit of paper it's confusing
