I discovered your videos three quarters into statics last semester, and I am really sad I didn't find you earlier! Now I am in mechanics and dynamics and I am really pumped to be able to have you as a resource. You're an excellent teacher, and I noticed it's because you cut right to the important bits.. the bits we need help understanding. Thank you for these series!
You are the number 1 mentor in UA-cam I am preparing for FE mechanical exam So far I did not find any mentor better than u Thanks again for your time. Guven
Thanks a lot for the course! Trying to get a pass for my resit and this helps a lot! The study material also gets a lot more enjoyable the way you present it, very uplifting! striving to be as positive as you haha
the moment you said freedom units i found it so funny that im handing my fate of getting the 1st on my class or not in your hands. ill keep on studying using your courses. thank you so much for the hard work you put in, as they say in islam “If a person teaches me one single word, he has made me his servant for a lifetime. “. so literally i owe you more than i can pay.
Beautiful as well as ver very helpful video ,i do have one question tho.How come and we did A=π (10)^2 and not A=π (20)^2 (20 being the diammeter of the cable) .Thank you for your helpful explanations and beautiful layouts.
because the formula for the area of a circle is A=pi*(r)^2, if the diameter is 20mm, then the radius is 10mm, and that's the value we should use in the area calculation.
Put the AB and BC coefficients in a 2x2 matrix [A] and the constants in a 2x1 matrix [B]. Then do [A]^-1[B] and it gives you a 2x1 matrix. The first entry in that matrix is AB and the second is BC.
I solved for Tbc in the first equation and got 1.347Tba=Tbc which I then plugged into the second equation to solve for Tba and then after getting Tba, I plugged it into 1.347Tba=Tbc to get the second force
To find Tab, you want to find Tab(cos50), Tab(sin50) using statics and free body diagrams and find the resultant of the two. Once you find those two, you square them, add the two and then find the square root. You would do the same to find Tbc.
I think his wrong tbc and tab using system of equations too find 2 unknowns His wrong because technically if you plug tab to find other tension it doesn’t give such answers

I love the way you connect the resolution of forces with the calculation for normal stress, it makes far more sense like this
FREEDOM UNITS
Wtf is a kilometer
You are the number 1 mentor in UA-cam
I am preparing for FE mechanical exam
So far I did not find any mentor better than u
Thanks again for your time.

Thanks a lot professor Hanson for that great effort. Ps. 0.280 mpa equals 280 kpa not just pascal.
I'm just reviewing my academic field for fun and brain exercising. My job field is different now. Thanks for your videos
OMG just learning in 14 minutes what I can't learn in 2 hours!!! Thanks so much!
I like how it ends exactly at 2:54 (...cm) when he says "Freedom Units!"
Thanks a lot for the course! Trying to get a pass for my resit and this helps a lot! The study material also gets a lot more enjoyable the way you present it, very uplifting! striving to be as positive as you haha

Absolutely incredible....One question sir can you show me steps on how you calculate 87.93 N and 65.3 N? I would be grateful.
@ 13:42 Dr. Hanson got the unit wrong.. it must be in KPa since he multiply the answer by 1000 and the unit before the multiplication is MPa
He actually corrects it at the end as he always does...but this time it’s in subtitles. It happens to the best of us too:)
@@ShAlAmAnAyA3 yeah haha i didn't notice because I skip the remaining part of the vid... and I immediately go to the comment section

Thanks Professor Hanson, the explanation is very clear and easy to follow.
What are you studying in school?!
@@thuwaybahmuhammad6071either mechanical or civil engineering
is this the same course with MECHANICS OF MATERIALS
Yes it is
easy and highly elaborated .
From Iraq , Thank you very much
The best mechanic of materials course. Helal dayııoğluuuuu
Bu yetiyor mu knk ,geçtin mi
I was so confused until 10:45. I paused and tried to see how on Earth T_BC became T_AB. If only I had waited literally 10 more seconds
You're good, what's system solver on a scientific calculator
really needed this class, my teacher is not with it at all
Bless your soul man.
I love you so much thanks for saving my grades
Thanks you so much professor
At minute 10:16, how did he find Tbc and how did he find Tab? What did he do to find them?
He use simul equation by the calculator, Tcb was X and tab was Y
I just did it manually
Why did not he consider reactions from fixed suppport?
how do you know when to use cos or sin
The unit of stress in BC is 280 kPa not Pa
what are v and m ?
Cool lecturer 😊😎
Wonderful Lectures ! Thanks.
How did he get from the 2 equations to the answers? TBC = 87.93N and Tab = 65.3N
from equilibrium formulas from statics, review global equilibrium especially
Recall a system of equations from [pre?] algebra. This time treat T_ab and T_bc as if they were “x” and “y”
Put the AB and BC coefficients in a 2x2 matrix [A] and the constants in a 2x1 matrix [B]. Then do [A]^-1[B] and it gives you a 2x1 matrix. The first entry in that matrix is AB and the second is BC.
I solved for Tbc in the first equation and got 1.347Tba=Tbc which I then plugged into the second equation to solve for Tba and then after getting Tba, I plugged it into 1.347Tba=Tbc to get the second force
God bless you man, thank you
Ahla 3alam jeff
Thank you so much for this!!
Thank you
Freedom Units!! Semper Fi! 😂🤟🧠💥
Is not cos50 0.96? And cos 30 .15?
This is a delayed response, but it looks like you were working in radians, make sure your calculator is in degrees. Hope this helped!
I for one liked the math joke. Gj sir
I made the SAME mistake of doing Pa instead of kPa when I did it
Thanks for the good work✊🏾
can someone explain me how he get TAB and TBC anyone? i need answer right now please
Very nice!. Greetings from Peru. 0.280x1000000=280 000????, M = 1000 000 ??
القم يامشعل
found Tab=188.68 and Tbc=254.17
see you next year
wow hahaha just as expected I came back
Go easy on him for mixing kPa and Pa. He was probably under a lot of pressure.
🤔🤔I wonder what Jeff knows about getting stepped on by some heels. Oddly specific example.
Isn't Tbc and Tab wrong in 11:11
Nope I found nearly same results as in the video
you need to put in the entire cosine and sine functions in sys solve rather than rounding to 1,000th place like written on board.
Now how to find average normal stress
Just the stress in the middle of whatever your dealing with. I.e if you have a beam, the average stress would be the stress in the middle of the beam
India 🇮🇳
When I plugged it in
Tab=22.3
Legend
any aerospace engineering majors here?
what was your question?
@14:56 how to make Tbc and Tab??
Sorry i don't understand speak English
To find Tab, you want to find Tab(cos50), Tab(sin50) using statics and free body diagrams and find the resultant of the two. Once you find those two, you square them, add the two and then find the square root. You would do the same to find Tbc.
@@joeyfalcon3278 when i do that, i get 1.0001 on the calculator for Tbc, I sqrt((.643)^2+(.766)^2)=1.00010, am i missing a step or?
Close to 42,000 views and less than 1000 likes!? This doesn’t sound right!
Can someone please explain how he got Tbc=87.93 and Tab=65.3. I can't figure it out
He use his calculator's mode in finding the unknowns, but u can also do some simple algebra
system of equations
I think his wrong tbc and tab using system of equations too find 2 unknowns
His wrong because technically if you plug tab to find other tension it doesn’t give such answers
@@toozzzy396 It's not wrong you have two equations with the same two unknowns. So sub one equation into the other so there is only one unknown
*F R E E D O M*
*U N I T S*
I think it is wrong TBC and TBA because 0.643+0.766=1.409 and 100÷1.409=70.972 this is equals to TBC
I found these videos too late.. lol
Math joke🤣🤣🤣
lmao freedom units
so many ads it sucks
