Find the tipping point!
Looking down onto the boat:
Measure:
Weight of sail and boat (in grams)
Lengths of boat and sail (in cm)
Lengths to center of mass of boat and sail (where does it balance?)
Example:
BL - boat length
al - axle length
S = Distance to sail
Fsj - force of sail pulling down
fbj = force of boat pulling down
BC = Distance to boat's center of mass
SC = Distance to Sail's center of mass
B° = Angle between boat and tipping axis
db = perpendicular distance between Fbj and tipping axis
ds = perpendicular distance between Fsj and tipping axis
S° = angle between sail and boat
Set up an excel file to calculate everything
(note, the numbers below are made up)
Test your calculations - use a protractor to measure the angle where the boat tips over, how does it compare?
