Hi, I'm making an animation of how a boat behaves when hit by a wave. This is how it looks like after the wave: (see attachment) At this point there should be a righting moment that tries to balance the boat by turning it clockwise. Which point does the boat rotate around? I'm not sure because the forces act on the C of B and the C of G and so I was thinking it would be the black dot, but shouldn't the C of B not move since it is a circular bottom? What do you guys think? Thanks! ------------------ EDIT: Ok so I tried to animate it: http://www.ironwhisk.com/wordpress/wp-content/uploads/2012/12/test.swf If this motion is correct, then does that mean that the fulcrum moves? Why?
