12 lis 2017 · The goal of this lesson is to explain how sailboats work by exploring basic physics principles. At the end of this lesson, students will be able to identify the forces acting on a sailboat...
17 maj 2017 · The effort and resistance forces are combined on a simplified 2D model of a sailboat to show how the boat develops thrust, which propels the boat forward. In this video, the lift and drag...
18 cze 2017 · This video shows Hallberg Rassy 48 Elysium in heavy weather off Cape Gris Nez, northern France in 2014. The yacht seems to be handling well, able to use a Raymarine lineair 7000 autopilot depsite...
With razor-sharp hydrofoil catamarans that help them hit speeds of 60 miles an hour, the athletes of SailGP are pushing the limits of physics and human endur...
1 lut 2008 · Forces on a moving sailboat. (a) Sail and keel produce horizontal “lift” forces due to pressure differences from different wind and water speeds, respectively, on opposite surfaces. (b) The vector sum of lift forces from sail and keel forces determines the boat’s direction of motion (assuming there’s no rudder).
One of the most important facets to understand when learning about how a sail works under the magnifying glass of aerodynamics is understanding the forces at play. There are four fundamental forces involved in the combination of aerodynamics and a sailboat and those include the lift, drag, thrust, and weight.
In this course we'll be discussing how your sails and keel work, and the different forces working on your sailboat.
