SOLAR BOAT ENGLISH 20MB.avi
This solar boat has been designed by LG in korea and made available through the department of physics in Pune university. this is a ready made kit. you need to assemble it. here is a solar panel with a toy motor and a worm gear. when you keep it out in the sun it rotates. once the shadow falls on the solar panel the motor stops. place the motor in its plastic casing and this is the solar panel. this is the body of the boat. these are the styro foam mounts, with a hole in the middle where the main axle will come. this is the pilot.
And this is the mount for the solar panel which can be adjusted. now place the motor along with the worm in position. place the solar panel on its mount which is adjustable. now place the steel axle with the gear in the middle and place two pedals on the ends. now this is the entire assembly of the solar boat. you can see that worm is with alignment with the gear. if the gear moves, both the pedals will move. this is the solar panel whose angle can be adjusted so as to orient it towards the sun. if you place the solar.
Boat in the sun, the solar panel will produce electricity which will run the motor, which will run the worm gear and gear in the middle will operate the pedals. when the shadow falls, the boat stops. now place the solar boat in a big tub of water. sun will fall on solar panel, the boat will run and the boat will go forward. when the solar panel comes under shadow, the boat stops. right now its turning, pedals are moving and boat is moving round and round. but as soon as the shadow falls on solar panel, the boat stops. its a nice.

That don't do do do do him wooden boat building plans learn I just wanna make key really quick tutorial did tell you how cool I think Michael plans to calm really years how well my ged online I was looking for a boat that I can build with my son and my father my dad still want to build a boat ever since he got out the Navy and so when I come on there I saw 500 different designs they're all stepbystep instructions for each design can be by the way the materials.
Candy dimensions you wooden boat building plans suggested they work perfectly we've got a beautiful new bass boat and this is my dreamboat really we're gonna go hit the water here hopefully next week and we should really be done by then so I'm I'm really excited my son has never been able to spend this much time with both me can my father and so is having a lot of fun so it's really been able to bring the boys together wooden boat building plans and we're gonna do enjoy it may owe it all to you.

DIY Dock Protector
Boating is a huge part of cottage life but there's one thing about boats thats got me stumped What's the point of having a rub rail if the darn thing never touches the dock It's about as useless as having a parachute at a spelling bee Sure boat bumpers do their work, but they wear the side of the boat big time Well today we're going to bridge that gap between boat and dock To illustrate we have a boat.we have a dock and our boats even equipped with a rub rail.
So what's the issue Well, the problem is that the boat rides above the dock most often in order to bridge that gap most of us add bumpers bumpers wear on the haul.so what if we could turn the dock vertical therefore allowing the rub rail to do its job well we could do that simply by adding a couple pieces Every boat and dock is unique For my boat, my dock, I determined thirty two inches was the right height so all we need to do now is mount them the dock.
I'm going to do that with lag bolts and recess the holes because I'm also going to add this dock edge and the head of the bolt would obviously interfere with the face of the dock edge Alright I got my lags I'm just gonna start them.I'm putting two in the bottom because that's where most of the torque is and then once the vertical pieces are mounted this will go overtop and its screwed in okay let's go down to the dock Most boats taper towards the bowel about midship.
So let's put one of our vertical pieces there And.maybe back here Alright so I'm bringing down this so the bottom of my vertical piece is flush to the bottom of my dock So I'm going to hammer this one in to get it started I'll use the ratchet for the bottom ones So next we're going to add this vinyl dock edge to our vertical, to give us even greater protection bigger boats are of course going to require more vertical supports and perhaps be struck back to the dock for increased strength.
But hey, we finally got the rub rail doing what it was designed to do and for us older folks.no I'm not included in that bracket sorry There's a handy grab rail so we can get in and out of the boat now I'm gonna hang onto the boat bumpers because a lot of dock owners aren't as cool as we are! But as far as I'm concerned we solved our problem.For Cottage Life, this is Wayne Lennox reminding you that a little project goes a long way at the cottage!.
How Does A Wing Actually Work
Shh. I've snuck into minutephysics' studio to explain how a wing actually works Hang on, something doesn't feel right. Ah, that's better. Now everyone knows that a wing generates lift due to its characteristic shape Since air travels farther over top of the wing, it must go faster than the air underneath so that both streams meet up simultaneously at the trailing edge And according to Bernoulli's principle, faster flowing air exerts less pressure than the slower air beneath the wing This pressure difference creates an upward force lift. Job done. Right Nope.
This simple explanation taught in many textbooks and classrooms has obvious problems Like how could a plane fly upside down Some planes like the Wright brothers' had nearly flat wings. So presumably air would travel the same speed over both sides and there would be no lift Plus experiments show that air streams don't meet up at the back of the wing. Air over the top goes significantly faster, reaching the trailing edge first. So how does a wing actually generate lift Well the key is the wing must deflect air downwards.
This can be achieved using asymmetric or cambered air foils Or by increasing the angle of attack Air under the wing is deflected down And by the coanda effect air above the wing is guided along its surface and down as well Since the air is slowed and deflected down by the wing, it pushes the wing up and back. Lift, and drag. This is in accordance with Newton's Third Law of Motion But hang on, if you can explain lift only using the deflection of air and Newton's laws, then the Bernoulli explanation must be completely.
Wrong Well, no, air over the top of the wing does go faster than air beneath, creating a pressure difference that generates lift Then this Newtonian explanation is unnecessary rubbish and the original explanation was right! That's not true either. The original explanation incorrectly assumed that air over and under the wing must reconnect at the trailing edge, and there was no mention of deflecting air down. Each explanation, done correctly, completely accounts for the lift generated by a wing. They're just two different ways of looking at the same thing.
