Tolerance Limits and Allowances - True and False

Tolerance Limits and Allowances - True and False Points : tolerance limits and allowances, mechanical engineering, metrology, mechanical technology, mcqs, evaluation, judgment, gauging, rating, consideration, analysis, examination, workup, test, review, objective type question and answer, true and false True and False
  1. Tolerance zone is defined by its magnitude (i.e. tolerance) and by its position in relation to the zero line. T
  2. In case of quilateral tolerances the total tolerance is specified on both side (Plus and Minus) of the basic dimension. F
  3. The closer the tolerance, the higher the cost and the greater the chance of rejection. T
  4. The nominal size of a dimension or part is the size by which it is referred to as a matter of convenience. T
  5. Bilateral tolerances usually have plus and minus tolerance of equal amount. T
  6. Tolerance are basically specified in three forms, i.e. unilateral bilateral and limiting dimension. F
  7. The diameter of a shaft is written in mm as 20±0.02, it gives the tolerance 0.04 mm or 20 mm diameter. T
  8. Standard tolerance is a tolerance belonging to any one of the standard grades. T
  9. In bilateral tolerance as related to a basic dimension is in one direction only. F
  10. The basic size should be midway between upper and lower limits. T
