Refer to the four-component assembly shown in Figure 9-14. Assume that the length of each component is normally and independently distributed with the means shown in Table 9-9. The specifications for the assembly length are 35 ±0.5 cm. Assuming that the natural tolerances (or process spread) for all four components are equal to each other and that the specifications barely match the natural tolerance limits, find the tolerances on the individual components.
