The smaller ones are in the range of 2.3…2.7 mm. The larger pieces of rocks vary in size between 3.3 mm and 3.7 mm. You want the smaller pebbles to fall through the holes while keeping the larger ones on the sift. Let’s say you are designing a sieve to separate 3.5 mm pebbles from 2.5 mm pebbles. In mechanical engineering, we are mainly talking about tolerances that apply to linear, angular and other physical dimensions.īut regardless of the unit, a tolerance states an acceptable measurement range from the base point (nominal value). For example, the working conditions may have tolerances for temperature (° C), humidity (g/m 3), etc.
Tolerances can apply to many different units. VI Why Tolerance Matters & Where to Use It? What Is Tolerance in Engineering?Įngineering tolerance is the permissible variation in measurements deriving from the base measurement.
