do not yield furthermore in subsequent loops through 116 the location of ce base can be changed to minimize the movement of ce child in step 118 a spring force balance analysis is performed to determine the movement of ce base with temperature in the current design of base part 14 as described above the spring force balance may be necessary when flexures 16 or flexure pairs 16 a are asymmetrically placed about ce base in step 120 the movement of ce base relative to parent structure 18 is compared with the desired tolerance if the movement is less than the tolerance then step 120 is followed by step 122 otherwise step 120 is followed by step 116 where the parameters such as aspect ratio r bh flexure length l f and the location of ce base are adjusted to reduce the movement of ce base relative to parent structure 18 in step 122 a numeral analysis is performed to determine the movement of ce child with temperature in the current design of base part 14 in one embodiment a finite element analysis is performed on the current design of base part 14 in step 124 the movement of ce child relative to parent structure 18 is compared with the desired tolerance if the movement is less than the tolerance then step 124 is followed by step 126 that ends method 100 otherwise step 124 is followed by step 116 where the parameters such as aspect ratio r bh flexure length l f the location of ce base are adjusted to reduce the movement of ce child relative to parent structure 18 various other adaptations and combinations of features of the embodiments disclosed are within the scope of the invention although examples for designing a base.
