When I solved for the moment of inertia about the y axis, i didnt do (200-y) because i thought that wouldve been the area _under_ the parabolic shape. am i wrong for doing this or is it valid? my answer was 80(10^6) mm^4.

You are the reason I understand this, my exam is tomorrow

thank you daddy

For my major, I was told to take a trig based physics class, which meant I was done with Calculus at Cal 1. So I never learned much about Integrals. Can you do some of the problems using the Trig-based approach?

Question will evaluating the point at point be different? I got F-EF =12

I honestly really look forward to these videos. The only TH-camr that explains it so well, so thank you

Ur explanations are spot-on, crisp clean, and right to the point.

how the f can you assume B is in the midpoint if there is nothing mentioned in the problem?

great job tmr is finally and i can say that u really helped me thanks bro

It is almost a mistake on his part in the calculations because he is supposed to add the moment approximately to both sides. This means that the sum of the moments about o for the resultant = 51x + 500, and the moment of the two forces before unification = 500 + 5.5 * 36 + 12 * 15 = 878 ....... And now. When we equal the two equations, 500 will subtract 500. When it goes against the sign, then 378 will be added. Dividing the result by 51 will end up being 7.411.

This was a big help, thanks!

Hi i would like to ask u another question can i?

I can actually pass my class now, thank you.

muchas gracias

Thank you my friend

How did you come up with integral y^2 * dA ?

this was very helpful, thank you

i love that you explain everything, even if it might be obvious. thanks to you, i finally know where to cut regarding method of sections. you're the best!

Why are you neglecting to include the vertical component forces at C and D in the free body diagrams? Why are you zeroing the component forces at these points. Despite it not asking for them they still exist and can't exactly be ignored.

Thanks, man. You're my saviour

i think for AC moment it should be (2.25)(0.5)?? pls tell me if i`m wrong😬

Thank you. The teaching was very concise and helpful.

Shouldnt r dot = 0.4*theta*theta dot not just 0.4*theta dot?

hi, do you have a lecture video regarding to this topic??

Can i assume they are symmetrical?? I hope i can get a reply What should i do if I were task to find every truss using the method of.Section in This problem for example?. Is it safe to assume the value i get for CE Is equal to BF???

a_A,t=0 due to no slip, a_A,n = w^2*r j =a_a. a_c = a_A + alpha x r_C/A + w x (w x r_C/A). Thus a_c = -10.01i -0.3656j. Not sure about a_b but the approach appears to be incorrect when applying to a_c

Why r we ignoring reaction forces

Damn bro, you explain so well. Thanks a lot 🙌

Sir, which book is this ?

wouldn't the moment about B also be an unknown? Why isn't it considered an unknown?

Bro, I really miss you. If you still here in this channel, leave a comment here Love your videos and appreciate your enthusiasm

Hi from 4 years later❤ hope you have a nice and wonderful day, man🎉❤❤ Thanks for your help❤

shouldn't f and p have opposite sign because they are opposite direction

I wanaa your username instagram plz to communicate with you 🙏

How could the distance be 17.9 m if the maximum distance it could be is 7.5 m + 4.5 m = 12 m. it being 17.9 m from O would mean that it is not located on the beam.

Moment about point H is easier.

Thank you buddy. It is really helpful

❤❤❤

This is very important vidio. your channel be blessed my Lecturer.

I need a man like him during my engineering exams🥺🩷

why is rp = ra? Why can we neglect the other support for the first part?

muchas gracias saludos desde peru

Just wanna ask how did you get 39.96 using scical? I hope you’ll reply ASAP huhunesss

thank you for making this simple

Thank you very much. I was able to understand thanks to you. ❤ I watched you from Turkey. Greetings.

Awesome video helped with my homework.

Thnxxx

is dy for lower"1" shape similar to upper"1" shape sir

Great video man

Hii, from Philippines, why in respect to y-axis, you did not subtract the y from 1 to get the dA of the formula?
