Weight and cost estimate for fabrication
The total weight and cost estimate was calculated by dividing the total volume
of the titanium rod given the project budget by its cost. The volume and mass
were determined for the individual parts and totaled, and to determine the unit
costs, the price per volume of titanium which was obtained above, was multiplied
by the volume of each component. Fabrication costs were also taken into account.
The estimated total cost of the fabrication of one unit was estimated to be
about $6.90, and the unit’s total weight is 0.32 g.
