I am not sure what you are referring to when you say changing line of a force. Can you elaborate please?

@@QuestionSolutions In statics, when you move a force to a different point not on its original line of action, the effect of this movement is represented by an equivalent force-couple system. So basically moving the force somewhere that is not along its line of action.

@@KeidenIsKayden I believe I have videos on that topic, though it's called something else. Please check the statics playlist.

@@QuestionSolutions Great, I will check now. Do you by any chance also have a video on finding where a resultant vector intersects a plane?

Thanks for the feedback :)

Thank you very much!

I don't use any programs to simulate questions. I animate them by hand the best I can :)

Can you provide me with a timestamp please?

You're very welcome!

Glad to hear!

You're very welcome! Best wishes with your studies.

Thank you very much for your kind words. I really appreciate it. :)

Please give me a timestamp so I know where you're referring to. Thanks!

nvm im slow i got it

Not sure how that pertains to this video? This video doesn't refer to NCEES manual, I am sure a lot of other things are not in that manual too. I don't really know how to answer questions like these. 😅😅

It didn't say, 200000 KJ?

At the joints? You can guess a direction, if you get a negative value, then it's opposite to your assumption, but the magnitude value is correct.

If you tell me what you didn't understand, I might be able to help you. Unfortunately, analysis of trusses requires you do have fundamental knowledge about forces and how to solve for them. If you're trying to learn from scratch, you have to start at the beginning of the statics playlist and learn the fundamentals, otherwise, it is like trying to climb a tree starting from the middle.

@@QuestionSolutions you have videos on those too…?

@@ecstasygaming9235 absolutely. See: czcams.com/video/Ixv1QYUAMWk/video.html

Glad to hear :) Keep up the great work!

Thanks, and to answer your question, please see: czcams.com/users/shortsP029mqnp4XY

@@QuestionSolutions thank you bro I always use your videos for my exams. Studying to become a BioMedical Engineer in Ireland, all credits to you. 🔥

@@killianbolly6449 Glad to hear these videos are helpful. I wish you the best on your journey to become an awesome Biomedical engineer :)

I am unsure of what you're referring to. Can you tell me how to replicate this problem because I am unable to do so on my end.

Please use timestamps.

@QuestionSolutions 6:10 Why is it on the top

@@LOID-wt4dy We need that angle to figure out force DE. It's the angle the force makes with the horizontal plane line at the very top.

@QuestionSolutions Can I still use invers tangent regularly if it's a different right angle. It's hard to explain.

@@LOID-wt4dy You can use it whenever you want as long as you use the proper sides and it's a right angle triangle.

I have no clue where you're referring to. You have to use timestamps.

@QuestionSolutions At 2:29 why did you put -8?

@@LOID-wt4dy I think you're referring to 3:07 right? Here, we assumed up to be positive. Since the 8kN force is facing down, it'll be negative.

Thank you

Happy to help :)

Superheated vapors are superheated vapors, they don't change. Only compressed liquids are treated as saturated liquids at a given temperature. :)

@@QuestionSolutions oh thanks, I thought the process change conversely

Please give a timestamp when asking a question. I am not sure where you're referring to. Thanks!

That's correct.

Which parts do not change in length?

Notice how we got a negative value for AGy. So initially, we assumed it to be up, but we got a negative value, indicating that it is actually facing down. With pretty much any force, you can assume a direction, and at the end, you will end up with a positive or negative value. If it's positive, your assumption was correct, if it's negative, then it's opposite to your assumption. In either case, the magnitude value of your answer will be correct.

I am really glad to hear it! The 2 force member should definitely be in your textbook, and hopefully your professor covers it, but if they don't, you can always ask during office hours.

You can choose whichever direction you want as positive, completely up to you.

Substitution method works for practically any number of given equations, so if you have 3 equations with 3 unknowns, you can do it, even more if you'd like. It just becomes a bit more tedious when there are too many unknowns.

So normal and tangential components are always perpendicular to each other. In other words, it creates a 90 degree angle between them. Here, we just have it bisected, so you end up with 45 degrees on each side.

Change in velocity as in dv/dt?

👍😅

I am sorry, I don't see the equation you're referring to at 5:02. Regardless, all values shown on the video are correct, there are no errors so somewhere in your equation, you made a mistake. Please double check your work.
