Thank you very much!

Great Video. I’ve wondered about this exact example for years. Thanks.

Me gustó el saludo jajaj, hola profe

A coping saw is a type of bow saw used to cut intricate external shapes and interior cut-outs in woodworking or carpentry. It is widely used to cut moldings, architraves and skirting boards to create coped rather than mitre joints.

Me like Thor: "I like this one"

Thank you so much for this video, really helpful.

Lift/Shear is 157.08, if moment is 66-2/3rds. Else moment is 33.333 if semi-span lift is 78.54. 4/3rds divided by Pi = 0.42441318. The span-wise location of the elliptical lift centroid, as measured from the fuselage side. 1/2 total aircraft lift multiplied by [(4/3)/Pi] is moment for a spemi-span of unity. Multiply by semi-span length outboard the fuselage for bending-moment. And multiply again by spar height...And again by ratio of distance of the area centroid of the spar caps from the outer most fiber of the top spar cap surface. Then divide by maximum allowable material compressive (yield) stress. Again multiplied by load-factor... This is minimum Ix for a spar at this span-wise station. Not accounting for additional spar(s) wing skin, or stiffeners contribution to bending resistance. Or accounting for moment reliving affect of wing weight and weight of fuel or landing gear located outboard of the 4/3rd over Pi span-wise station. Also doesn't account for mass position forward of the aerodynamic center, moment coefficient of wing at Vd, tail down-load, etc...

Thank you for uploading these videos …! I would appreciate if you could explain the last point about why the horizontal rope is not a good idea. My understanding is if the rope is horizontal or almost horizontal it is stronger than the weight it carries especially if the weight is too small and the strength of the rope is way higher than weight it carries.

Cool stuff, helpful for path planning. Thanks man

Wow

Hello gc

I have done that using jupyter lab. GD works but is slow compared to other methods. The Rosenbrock function is stll smooth

Thank you 🙏☺️

Why there is so many circles.

Thank you, in practice, you get the velocity readings as numbers not as a function that you already know, what to do in that case?

Very interesting!

There is no way possible from the dimensions you have written on the board to find a web of 35.

Brilliant explanation, thank you!

This is such a gold quality video explanation! You are amazing Professor! Thx a lot!

@03:58 - We English use Metric units now, we tend to refer to the old "Imperial" units as "American" sizes now 🙂. (Thomas Young was English btw). Anyway, great explanation and thanks for posting sir.

9:55 😂

Your amusing you make physics like game I wish to study in your claas

I find your programs very educational. Having had classes in linear algebra, i can say that your applied method now makes more sense to me.

Thank you, this really help me.

Is the elastic modulus always higher than the rupture modulus??

thank you for your video!

1.585D

Great explain ❤❤

A nice overview containing manual and symbolic integration and plotting the results. The shown commands provide nice plots with minimal effort. Especially I like how MATLAB uses common default values. For example, the additive constant C from the integration process is set in a way that the initial condition (t=0) for v and x is 0. It was a surprise to me that the integral boundary can be called t when the independent variable is t, too. It was explicitly mentioned that this violates no rules - and MATLAB accepts it - but in my understanding these are two separate things. The integral boundary is a static specific point in time at which the integration ceases. While the t in the formula is floating and takes all values within the integration boundaries. Anyway, it is simple and it works. A numerical integration is not shown, though. Instead the formulas obtained in the previous symbolic step were re-used. Tiny correction: The expression for x in 18:14 contains '..+3*t...' which is wrong. It should be 2*t since the expression for v contains a 2, not a 3.

Excellent video

How embarrassing for you to be using units that people who actually make stuff found effective for hundreds of years before moving decimal places with calculators was a thing

thanks for the great explanation and thanks for using metric.

So very nice, great. Thank you tecaher.

You're so likeable and Gumbo is to die for cute! Thanks for your videos!

Merci beaucoup.

You're a god

Sir, how is it possible that concrete has a lower young's modulus than steel?

Lec : I did this in undergraduate and I didn't really understand actually my mind : You are good by not understanding😂😂

What does it take to soak up as much knowledge as you?

18:40 Because Apollo-Saturns were fake rockets 🚀

thanjk you! :)

This is a cool, simple explanation. I googled "How high does a building need to be to require a flying buttress and this video popped up" It doesn't answer the question exactly but the general terms are nice.

Fantastic explanation and experiment. I'm trying to understand the dynamics of riding electric unicycles and one of the biggest unknowns in the gyroscopic calculations is the moment of inertia of the rim and tire. This looks like the best way to measure it. Thank you so much for the video!

Thankyou!

A millions of thanks sir... I was being wrong,,, because I didn't multiply 9.81 m/sec. square with weight. Thanks for my clarification

Thank you very helpful video ❤

Nice work, and relevant to a school project here in NZ!

Thanks for the explanation..really helpful
