The Dubai government has purchased the historic vessel for $100 million and plans to turn it into a fancy hotel. While the QE2 is sailing into the sunset, she has plenty of friends that plan to stick around and take advantage of the lucrative cruise industry. As you are soon to learn, ...
The amount of drag is proportional to the airspeed of the hang glider: The faster the glider moves, the more drag it creates (see How Gliders Work for details). How a pilot maneuvers a hang glider As with soarplane gliders, the balance of these three forces (lift, drag, gravity) ...

Sailing into the wind is not possible.If you try,the sail will flap and the boat will stop.You may want to go in that direction.It is possible,but you can't go in a straight line.You must go first in one direction and then in another.This is called tacking.When you are tacking,...
What does beating mean in sailing? Beating isthe procedure by which a ship moves on a zig-zag course to make progress directly into the wind (upwind). No sailing vessel can move directly upwind (though that may be the desired direction). ... A ship that is beating will sail as close...
2. How does a wind power work? A. The generator turns the propeller blades and produce electricity. B. The tall tower helps turn the energy in the air into electricity. C. Warm air rises and makes the propellor move round. D. The propellor blown round by wind turns the generator to ...
It helps teach the difference between laminar and turbulent flow but in a very simple way and also helps understand sailing geometry and avoiding getting stuck into the wind. The Deskbreeze is a revolutionary way of visually teaching youngsters (and adults) how a sail works!
