1. Consider the two-component assembly shown in given Figure. Suppose that the mean lengths are given as μ1=14 cm and μ2=8 cm. Assuming that the specifications for Y are 6± 0.2 cm, what are the tolerances for X1 and X2? Assume that the variance of X1 is three times as large as that of X2.
2. Four metal plates, each of thickness of 3 cm, are welded together to form a subassembly. The specifications for the thickness of each plate are 3± 0.2 cm. Assuming the weld thickness to be negligible, determine the tolerances for the assembly thickness.
