Problems 1-1 Through 1-6 Are For Student Research. No Standard Solutions Are Provided.

1-7 From Fig. 1-2, Cost Of Grinding To  0.0005 In Is 270%. Cost Of Turning To  0.003
In Is 60%.
Relative Cost Of Grinding Vs. Turning = 270/60 = 4.5 Times Ans.

1-8 CA = CB,

10 + 0.8 P = 60 + 0.8 P − 0.005 P 2

P 2 = 50/0.005  P = 100 Parts Ans.

(b) X1 − X2:
X1 − X2 = X1 + E1 − ( X 2 + E2 ) Ans.
E = ( X1 − X2 ) − ( X1 − X 2 ) = E1 −

1-11 (A) X1 = 7 = 2.645 751 311 1
X1 = 2.64 (3 Correct Digits)
X2 = 8 = 2.828 427 124 7
X2 = 2.82 (3 Correct Digits)
X1 + X2 = 5.474 178 435 8
E1 = X1 − X1 = 0.005 751 311 1
E2 = X2 − X2 = 0.008 427 124 7
E = E1 + E2 = 0.014 178 435 8
Sum = X1 + X2 = X1 + X2 + E
= 2.64 + 2.82 + 0.014 178 435 8 = 5.474 178 435 8 Checks
(b) X1 = 2.65, X2 = 2.83 (3 Digit Significant Numbers)
E1 = X1 − X1 = − 0.004 248 688 9
