									 Stress analysis of SpindleHousingFEA


Note:
Do not base your design decisions solely on the data presented in this report. Use this
information in conjunction with experimental data and practical experience. Field testing is
mandatory to validate your final design. COSMOSWorks helps you reduce your time-to-market by
reducing but not eliminating field tests.
