An occupations in mathematics in which the person analyzes and calculates weight data of structural assemblies, components, and loads for purposes of weight, balance, loading, and operational functions of ships, aircraft, space vehicles, missiles, research instrumentation, and commercial and industrial products and systems. Typical esponsibilities include:

• Studies weight factors involved in new designs or modifications, utilizing computer techniques for analysis and simulation.
• Analyzes data and prepares reports of weight distribution estimates for use in design studies.
• Confers with design engineering personnel in such departments as preliminary design, structures, aerodynamics, and sub-systems to ensure coordination of weight, balance, and load specifications with other phases of product development.
• Weighs parts, assemblies, or completed product, estimates weight of parts from engineering drawings, and calculates weight distribution to determine balance.
• Prepares reports or graphic data for designers when weight and balance requires engineering changes.
• Prepares technical reports on mass moments of inertia, static and dynamic balance, dead weight distributions, cargo and fuselage compartments, and fuel center of gravity travel.
• May prepare cargo and equipment loading sequences to maintain balance of aircraft or space vehicle within specified load limits.
• May analyze various systems, structures, and support equipment designs to obtain information on most efficient compromise between weight, operations, and cost.
• May conduct research and analysis to develop new techniques for weights estimating criteria.
