The bell crank system shown in the figure below is attached to a horizontal spring BC with stiffness k = 2 kN/m and a pin support at point A. Spring BC is unstretched when angle 𝜃 = 0°, and the bell crank is in equilibrium under the effect of the external force F when angle 𝜃 = 15°. If spring BC remains in a horizontal position at all times due to the roller at C, determine the following when t...

Переглядів 20 тис.4 роки тому
A semicircle of radius "a" is in the first and second quadrants, with the centre of curvature at the origin. Positive charge Q is distributed around the left half of the semicircle and negative charge -Q is distributed uniformly around the right half of the semicircle. What is the magnitude of the net electric field at the origin produced by this distribution of charge? DISCLAIMER: Question tak...

A solid sphere of radius R contains a total charge Q distributed uniformly throughout its volume. Find the energy needed to assemble this charge by bringing infinitesimal charges from far away. This energy is called the “self-energy” of the charge distribution. DISCLAIMER: Question taken from University Physics 14th Edition

Grazie, funziona! Non capisco sinceramente tutta questa involuzione per fare una cosa banale, pollice meno per Inkscape su questo aspetto!
Hi, I'm doing this problem from a textbook. For Part A, the textbook says the correct answer is kQ/x(x-a); there is apparently no inclusion of r. Does this have something to do with the problem stating x>a?
Sir I am from India In my inksacape 1.2 not working your trick
Shouldn't the integral be from a to a+r
Please continue your channel the world needs you
love you man
you saved my life
how tf it became -1/x??
that is the integral of 1/x^2
For the charge at the end, if it were the same charge everywhere, would lambda = 2Q/pi*r ? Also, where did you get the 2Q on top if there is no 0.5*pi*r below the Q?
Thank you
Thank you! 😀
Thanks a lot for this video!
2:00 Sir, I have question 1. I want know How to calculate Right side equation Which paper is it from?
Could you please solve this equation without using mathematica 0.005= (490/159195)*(2Nf)^-0.065 + 0.463*(2Nf)^-0.65
Where is the 2 from I keep getting 2 not 4 at the end
Great explanation! Love the granularity
amazing, thank you
At 0:30 why did you take log(192/167) - b? shouldn't it be log(192/167) +b..
thank you so much, you saved my life in engg calc this week
I don't see how this works with your cos(theta) trick because that is only for right triangles, not arc lengths. If you used cos(theta) with that radius, you cut yourself short on the x axis.
My man. Thank you.
Thanks
Do you have any references for this particular formula? As I am getting the formula in various journal articles in a different way such as - S = A (Nf)^b, so here direct S is taken, while that of in your video, delta S (Smax-Smin) is taken.
I find it also strange.
This video was really helpful 👌
i think the greater than and smaller than signs are switched. Shouldn't High cycles be when the cycles is greater(>) than 10^4 and low cycles smaller(<) than?
This solution is valid... and I believe it is a good approximation. However, the extension of the spring is not exactly as given due to the fact that point B travels slightly vertically (y direction) as well as horizontally (x direction). Thus the extension is slightly more... and the resulting force on the spring will be slightly more.
Yes sir ❤😊
What a unit
thank you so much this video is extremely helpful , but I was wondering why we treated the electric field as it is from one source ,, like I thought the the X-component of each electric field (one from -Q and +Q) is going to cancel each other and we are going to only integerate to get the y component ( Sin will be in our integeration instead of cos) ,,so why we did only use COS like there is no other component. thanks in advance.
Thank you so much! I suscribed your channel :).
why is stress range twice the amplitude
Thank you so much for this video!! I really needed it and you're very good at explaining
Lets get into it #peppereng
nice
Crazy twist at the end
not normally but often great content
This was so helpful I passed my class because of you and your voice sounds so hot
I am using inkscape version 1.1 and its not working
At 20:00 how do you get d/dx (x^3sec^2(x)) to be like that? You say you apply the chain rule but shouldn't you apply the product rule? d/dx(f(x)*g(x)) = d/dx(f(x)) * g(x) + d/dx(g(x)) * f(x). I mean d/dx(x^3sec^2(x)) is 3x^2sec^2(x)+2sec^2xtanxx^3. The bottom derivative is also not correct. It is not 2sec^2(x) but rather -2sec^2(x). Seemingly great video up until that point though.
fuckingHard!!! Thank you very much.. :)
Thanks! Good work
unfortunately, it didn't work for me :( any different ways to correct this ? I tried to draw the text box before typing, the symbol of block-justify turned to be on, but still, when i click it, it doesn't block-justify the text :/
The angle calculations for alpha and gamma must be zero because the angle between the x and y axis is 90
Ah yesthat's an error in my diagram. Thanks for pointing that out! The 60deg should be from the purple x-axis to the blue bar. With this correction, the alpha and gamma angles are not 0.
Thank you so much for this!!
why is he pronouncing ln like "lawn"
thats how its supposed to be pronounced

Worked, but only when I inserted the text in a box, as you did, just a text object did not get this option.
Thank You!! super helpful :)
why this way doesn't work in my inkscape
What version on Inkscape are you using? I can't edit my text preferences in Inkscape 0.92
