Answer 1

Please rate the answer. Thank you.

Ans: Allowance = smallest clearance B. B (max) = 1.32 + 2x 0.21 = 1.74 Allowance = A (min) – B (max) 0.20 = (A-0.05) – 1.74 A = 1.99 O Amin= 1.99 -0.05 = 1.94 @ | Amax = 1.99 +0.05= 2.04 A = 1.99 @ Max. clearcance = Acmax) -B (min) = 2.04- (1.22+2X0.19) = 0.44
