STABLE EQUILIBRIUM UNSTABLE EQUILIBRIUM
Sail cars and sailboats use the wind to create
forward motion in similar ways. While the sailboat
needs its keel to channel the forces into a forward
motion, the sail car needs its wheels. Sails work
in three ways: If the wind is coming from behind,
the wind can simply push the sail and the vehicle
forward. This is called running downwind.
If the wind is coming from the side, the
sail redirects the wind toward the back, which
accelerates the wind backward and the vehicle
forward. The resulting force has a strong sideways
component, but the keel or wheels counteract that,
keeping the vehicle moving forward. This is called a
beam reach.
If the wind is coming more from the front,
then the sail must be brought in tightly. Now
the sail works like a wing, generating a lift force
perpendicular to the sail as the wind flows over the
two sides at different speeds. Here again the keel
counteracts the sideways force, leaving the forward
component of the force to move the vehicle forward.
This is called close hauled.
The models in this kit work best running
downwind, and it is difficult to get them to work
well otherwise. But experiment with them and you
might be surprised by what you can do!
Stability
The wheels and a low
center of gravity keep
the sail car stable so
that it doesn’t tip over.
If the wind is so strong
that it pushes the
center of gravity over
the tipping line, then
the car will tip over.

is cool!
