	The symmetrical pod is to be fabricated from three sections of metal sheet material and will consist of a cylindrical center with conical ends. The three pieces, once fabricated, will be welded together. The design specifications for this pod call for a volume of 1.0 m^3. It is desired to minimize the amount of material used in the design for reasons of weight and cost. What dimensions L1,L2 and D would you recommend for this design?  |
