章節(jié)摘錄
Some of these have to do directly with the dimensions, the material, the processing, andthe joining of the elements of the system. Other considerations affect the configuration of thetotal system. To keep the correct perspective, however, it should be observed that in many design situ-ations the important design considerations are such that no calculations or experiments are nec-essary in order to define an element or system. Students, especially, are often confoundedwhen they run into situations in which it is virtually impossible to make a single calculation andyet an important design decision must be made. These are not extraordinary occurrences at all~they happen every day. Suppose that it is desirable from a sales standpoint——for example, inmedical laboratory machinery——to create an impression of great strength and durability. Thickerparts assembled with larger-than-usual oversize bolts can be used to create a rugged-lookingmachine. Sometimes machines and their parts are designed purely from the standpoint of stylingand nothing else. These points are made here so that you will not be misled into believing thatthere is a rational mathematical approach to every design decision.
