Buoyancy Test (week 4)

During lessons, we did our buoyancy test but before that we calculated our safety factor for the surface vessel as shown in the picture below...

The task that was given to us was to find the metacentric height of our surface vessel, but first we need to find the maximum angle our surface vessel is able to roll before it capsizes.

The picture below shows a table of the maximum angle before it capsizes when adding a certain number of marbles to one side of the surface vessel.

The Picture below shows our calculation of the metacentric height of our surface vessel at its least stable roll axis which is 20 degrees.

The picture below is the detailed formula to finding the metacentric height of our surface vessel.
