It's also possible to use the matrix and use elementary operations to solve. If you keep the exact values, each column maintains the same denominator which makes for easier calculations. This way you don;t need to calculate 4 sets of determinants and use Cramer's Rule.
Yeah, this one is not to bad to do without Matrices, but some where you don't know the F it becomes very difficult, near impossible to do without Matrices.
Could You pleas help me to solve this question? Draw the free body diagram. If the balloon is subjected to a net uplift force of F = 800 N, determine the tension developed in ropes AB, AC, AD.
Why did you change the unit vector of AD, it was -0.492i -0.615j -0.615k, but you changed it to -0492i +0.615j -0.615k while multiplying with the force notation TAD. Correct Answer to this problem are: {Tb: -141.287624428452, Tc: 847.725746570709, Td: 565.150497713806}
tedious algebra. this is a static course, which means this is upper year engineering, you should already know how to use matrices to solve for determinants etc. i'm sure you took vector calculus or linear algebra before doing these types of problems, but to answer your question you would have to constantly use substitution and it would take forever.
essentially what he is doing is a Cross product. very easy to learn even if you don't know, there are some super easy videos to watch th-cam.com/video/qsgK1d-_8ik/w-d-xo.html
@@hans3331000 at least at our university normally you are in calc one or 2 while taking statics because it is a first year course here. So a lot of us do not know matrices, but he explained it very well to be able to implement it into other problems. Algebra is the other way and it would take several sheets of paper to finish the answer as these questions require a lot of time and thought to answer.
@@themainelife.2074 once again man, the link is above, you can complain or you can take the help. I'm a 4th year nuclear engineering student so trust me when i say if you're not good with linear algebra and matrices you're not gonna have a good time
Lasu engineering students i greet oo 🙋🏿♂️🙋🏿♂️😂😂
We mount 😭

For sure
Ahhh una dey here too😂

I had never used matrices before this video, super helpful and much more organized than using system of equations.
Excellent explanation! Step-by-step, quality video my friend.

what textbook is this question taken from?
Thank you so much for the video it helped me a lot .
So if you were not to use the matrix then you would need to use a long system of equations?
Yeah, this one is not to bad to do without Matrices, but some where you don't know the F it becomes very difficult, near impossible to do without Matrices.
thank you so much for showing how its done. i cant thank you enough

Very well explained, thank you.

Your wrong bru
The correct answer is in the back of the book, you are incorrect he is correct
He changes it back to correct for it in the matrix! I was confused about the same issue, he just never addresses it in the video
@@Nick1one_ what is the name of the text book please
you're a legend
Thanks
I'm not sure how to do this with matrices, how can I do it another way?

@@hans3331000 well look at you "nuclear engineer" learn to deal with people positively next time. you don't have to be an asshole
Really awesome video. great great great great.
Thanks lecture for this
thank you very much
pure gold
Thank you👏🏽
Uac for j and k are wrong?
I got 0.3939j and -0.6155k
Please stop with the matrices.
