21 Physical prototypes of engine parts. By modifying the spring constant to improve the HMMWV suspension design at the preliminary design stage, the load path generated in HMMWV dynamics simulation is affected in the suspension unit. In the detailed design stage, the objective is to assess and redesign the durability, reliability, and structural performance of selected suspension components affected by the added armor load that results in changes in load path and magnitude. Note that only a very brief discussion is provided in this introductory chapter.

If one chooses x ¼ 3, then (y À 2)2 þ 3 ¼ 0 does not have a real solution for y, implying that the vertical line x ¼ 3 does not intersect with the circle. Also, the implicit form may not be a single-valued function when there is a solution. 3(a), the curve is not single-valued along lines that are inside the circle and are parallel to the y axis. 1 A curve representation. (a) An explicit function y ¼ f (x). (b) An implicit form F(x,y) ¼ 0. 2 Conic curve representations. represented in such forms.
