OptimumDesign
I. FUNDAMENTALS
The concept behind optimum design is to get the most from an engineering
design with the least cost, effort, or materials. The analysis generally starts
with a
A. Criterion Function
C = C(x,... z,)
Generally there is only one such function and it can represent any or all of
the following
1. Cost of manufacturing a product
2. Total weight of a design
3. Power developed by a design
4. Energy absorbed by a design
5. Efficiency of the design
These are some of the factors which the engineer must take into
account to get the least or most out of their design with the criterion
function. There are other constraints that must be satisfied:
B. Functional Constraints
These are the physical laws which an engineer must follow for a successful
design
1. Stress equations
2. Calculations for thrust, lift, drag
3. Deflections
4. Buckling
