When performing DFA analysis, you should look for ways to increase part symmetry: (a) true, or (b) false
Solution
True.
One of the principal geometrical design features that affects the times required to grasp and orient a part is its symmetry. Assembly operations always involve at least two component parts: the part to be inserted and the part or assembly (receptacle) into which the part is inserted [15]. Orientation involves the proper alignment of the part to be inserted relative to the corresponding receptacle and can always be divided into two distinct operations: (1) alignment of the axis of the part that corresponds to the axis of insertion, and (2) rotation of the part about
this axis. If there is symmetry these jobs become easier and hence one should look for symmetry.
