You should explain what a "moment" is. Not everyone has a degree in mechanical engineering.

Thank you for this presentation ❤

Has any one ever seen an experiment proving the hypothesis that air destined to travel over the top of a foil increases its speed when it encounters the leading edge of the foil and begins its longer trip over the top? One could add two pulses of dye into a slip stream so that they travel on either side of a foil. The expected result, according to the explanation of lift in this video, should be the pulses arriving at the trailing edge in exactly the same relation that they arrived at the leading edge despite one pulse having to travel a longer distance. The pulse had to have received a force in the trailing edge direction to increase the speed component of the velocity. What generated the force int he trailing edge direction that increased the speed of the pulse that went the longer distance?

Interesting activity, thanks for posting

20:32 shows an SEM image of fluorescent protein rotating. it is so amazing. Can I get a reference on that?

wow it looks like she is having so much fun! she is definitely not reading anything

RESPECT = GREAT PRESENTATION

nice

Have you also investigated regarding LWL over the Hull Speed as yet conceptualising the boatbuilding with short LOD with wide Beam but all of my hull concept obtained semi displacements hull as enough to configurate proper ballasting systems using Gaff Rigs as main sail as yet I mention a pocket yacht with 16 or 17' LOD under the 20 or 21 LOA as though I was not properly schooled with degree but technically under the domestic doctrine standards nobody believe me with extra-curricular property especially within these curriculum aren't been part a standard curriculum here, as fell short some degree of misunderstanding enough to call me a delus

Excellent resource and a good introduction to the topic ❤

All i heard was words. I i kinda get it. Im knowledgeable with planes and helicopters and understand them easily but i just can't grasp sail boats.

why even bother assigning a dollar value to the production of ATP within a human body?

I understood sailing dynamics better from this ua-cam.com/video/FCcKeOmYHFY/v-deo.html childish video, than from the MIT engineering professor here. Cheers

You linear momentum explanation is ignoring friction. And if either of the balls spin, that affects the friction even more. And some of the energy is transferred into the sound so there are other factors at play.

thanks for talking about the physics of pool. I am interested in continuing this disscussion.

How long would DNA last on a piece of clothing. I am looking at a sixty year old murder. The clothing of the person was stripped off during the murder but perhaps something would still exist on the trheads.

the teacher assumes that the student knows what she's talking about without pointing to. She leaves the exercises with insufficient context to come to conclusions... she never took teaching classes

🤔

Why mole has a unit mol when it is a pure number like dozen? 🤔

Why mole has a unit mol when it is a pure number like dozen? 🤔

this is over any newbie's head just go find a sailing school and learn hands on it's too easy to over think sailing

Thanks , very informative video

I dont watch sailboat races I participate in them

99 . 7 percent of the population is enjoying nuclear technology halogenated vinyl and halogenated carbon erosion of atmosphere and fertility globally.

So the downwind quarter is the fastest quarters to sail.below 90 degrees to the wind. 2.0 times windspeed is maximum boat speed. But perfection is not a realistic goal. Vesta's speed can be reached in a full size sailboat design of normal academic design. If the keeling design is correct and the width is twice the height of the mast or greater.

The fastest direction is across the wind. The apparent wind ahead of the boat ends the speed of the boat.

The stem is the most important design quality of a sailboat design. Ballast the boat and keel the sails.

The stem is halfway between the mast and forestay of the largest sail. This is the point where keeling of the headsails begin and should relative to the sail area ratio of mainsail and headsails.

Lateral resistance ahead of the sail effort is essential. Mast and stem lateral resistance is essential to rudder control and lift.

The sailboat can sail up to twice the speed of the wind but this is theoretically perfect number and not physically possible. 1.5 times the windspeed is a realistic goal but without stem to stern academic keeling design this ambition can't be seen.

The center board should be directly below the mast and ahead of the mass. If you keel the boom the boat heels over before moving forward and has less sail power..

The keeling of the mast at the mast is often missing.

The mast should be keeled and the headsails keeled more deeply between the mast and forestay.

What is usually missing from sailboat design today is keeling design that has lateral resistance ahead of sail effort. The stem to stern academic keeling design reduces heeling over and increases speed of the sail boat. Most importantly this keeling design keeps the boat easily sailing into the wind and the sailor can easily keep the bow to waves and wind. This lateral resistance ahead of the sail area is essential to create lift and have greater speed.

Oh .. I dont get it. Bernoli or whatever air thing is never makes sense It cant generate enough lift to lift a 300 70kg adults and fuel and avionics right ? .. along with its own weight. .. the perpendi doesnr make sense

Good explanation ❤❤❤❤

thanks for the woderfull video.

I wonder how such a well designed system can creat it self by chance !!!!! it is hard for an engineer to buy.. it also goes against all enthropy and propabilities theories.

How does this work if there's a discord in all cells of the body? Like being coeliac or having a propensity to colon cancer due to genetics?

Utterly fantastic!

That's why i like youtube

Why do we have to eat? Michondria, Has baffled me, From learning from the the foods and air we take I is convert to Oxgyen.... Legends and myths I always wondered if man lived I tge carbon age Did he live on Oxgyen Belfast Ireland 🇮🇪 😎

I love burritos

I was under the impression that the proton pump is unidirectional in the counterclockwise direction and that there were gates that return extra and internal membrane states to original ionization.

Спасибо!

excellent presentation

She became a Patent Attorney. Life does not always take a person where one expects, does it?

fuck your white man science. you have ripped off indigenous Rang elders of which i am one and not even mentioned us. fuck you and this ignorant and racist video.

Thank you very much for your clear explanation.

unpopular opinion : very confusing and overstuffed presentation .
