Two shafts A and B have their diameters specified as 100

Two shafts A and B have their diameters specified as 100 ± 0.1 mm and 0.1 ± 0.0001 mm respectively. Which of the following statements is/are true

1. Tolerance in the dimension is greater in shaft A
2. The relative error in the dimension is greater in shaft A
3. Tolerance in the dimension is greater in shaft B
4. The relative error in the dimension is same for shaft A and shaft B

Tolerance of shaft A = 100.1 – 99.9 = 0.2
Tolerance of shaft B = 0.1001 – 0.0999 = 0.002m
Tol_A > Tol_B
