【正文】 calculations are necessary to ensure the validity of a design. In case of any part failures, it is desirable to know what was done in originally designing the defective ponents. The checking of calculations (and drawing dimensions) is of utmost importance. The misplacement of one decimal point can ruin an otherwise acceptable project. All aspects of design work should be checked and rechecked. The puter is a tool helpful to mechanical designers to lighten tedious calculations, and provide extended analysis of available data. Interactive systems, based on puter capabilities, have made possible the concepts of puter aided design (CAD) and puteraided manufacturing (CAM). How does the psychologist frequently discuss causes the machine which the people adapts them to operate.

In recent years, many products liability in litigation, the use of products and hurt the plaintiff accused manufacturer, and won the decision), (c) of the materials used all or some of the data, data, especially when the uncertainty longterm performance data is so, (d) quality control method is not suitable and unproven, (e) by some pletely inpetent persons choose materials. Through to the above five questions analysis, may obtain these questions is does not have the sufficient reason existence the conclusion. May for avoid these questions to these questions research analyses the appearance indicating the direction. Although uses the best choice of material method not to be able to avoid having the product responsibility lawsuit, designs the personnel and the industry carries on the choice of material according to the suitable procedure, may greatly reduce the lawsuit the quantity. May see from the above discussion, the choice material people should to the material nature, the characteristic and the processing method have prehensive and the basic unders
