How is the teacher testing the resulting shape? Is he/she using lead shot,
pea gravel, water. Is the teacher really looking for a boat/barge or the theoretical practical solution? Lead shot in the bottom of a hemisphere would be stable enough for a test and give you the least amount of surface area. Clark "surfnturf" wrote in message news:MIfee.1223692$6l.94600@pd7tw2no... There certainly are lots of cement barges plying the costal rivers of China. Staight sides and flat botton, but probably for ease of construction and load handling. Might want to play with the math a little to get a fix on the shape that encloses the greatest volume with the least surface area. Hmmm. Sounds a lot like half a sphere. Could cast it inside a basketball... surfnturf "No Spam" wrote in message news:UTeee.7459$Rl6.7151@trndny08... I think I would model it after river barges. very flat bottom, straight sides and rounded up at both ends. Rectangle shape. It is used to haul tons of coal around here every day. It is also a very simple shape to produce. Also agree with everyone else that you need a mesh inside to keep it all together. |
