Topics of this game:
  • On a technical drawing, the length of a part is given as 1.58 ± 0.002 inches. What is the percent tolerance to the nearest hundredth of a percent?
  • A length is measured to be 0.647 inches with a tolerance of ±0.004 inches. What is the percent tolerance to the nearest hundredth of a percent?
  • A length is measured to be 167.00 mm with a tolerance of ±0.50 mm. What is the percent tolerance to the nearest hundredth of a percent?
  • On a technical drawing, the length of a part is given as 33.48 ± 0.07 mm. What is the percent tolerance to the nearest hundredth of a percent?
  • A length is measured to be 1.79 inches with a percent tolerance of ±0.15%. What is the tolerance to the nearest thousandth of an inch?
  • A length is measured to be 0.792 inches with a percent tolerance of ±0.20%. What is the tolerance to the nearest thousandth of an inch?
  • A length is measured to be 212 mm with a percent tolerance of ±0.05%. What is the tolerance to the nearest hundredth of a millimeter?
  • A length is measured to be 52.60 mm with a percent tolerance of ±0.10%. What is the tolerance to the nearest hundredth of a millimeter?
  • Specifications call for a hole diameter of 2.875 ± 0.005 inches. The hole is later measured at 2.871 inches. Is it within specified tolerance?
  • Specifications call for a machined part to be 148.25 mm in length with a tolerance of ±0.22 mm. The length of the machined part is later measured to be 148.49 mm. Does the machinist's error lie within the specified tolerance?
  • Specifications call for a notch in a machined part to be 0.725 inches in length with a percent tolerance of ±0.15%. The notch in the machined part is later measured to be 0.727 inches. Does the machinist's error lie within the specified percent tolerance?
  • Specifications call for a machined part to be 192.25 mm in length with a percent tolerance of ±0.08%. The length of a machined part is measured to be 192.10 mm. Does the machinist's error lie within the specified percent tolerance?
