Document Summary
Problems 1-1 through 1-6 are for student research. 1-2, cost of grinding to 0. 0005 in is 270%. Cost of turning to 0. 003 in is. 10 + 0. 8 p = 60 + 0. 8 p 0. 005 p 2. Relative cost of grinding vs. turning = 270/60 = 4. 5 times. To offset the absolute uncertainties, the design factor, from eq. (1-1) should be. 2 (b) x1 x2: (c) x1 x2: x. 1-11 (a) x1 = 7 = 2. 645 751 311 1. = 2. 64 + 2. 82 + 0. 014 178 435 8 = 5. 474 178 435 8 checks.
