Some factors include: natural resources, immigration, government, entrepreneurs and inventors. It led to rising standard of living, improvement of transportation, and growing populations.
HOPE THIS HELPED!!
Because the unilateral system is easier to get as close to the dimension the engineer specified.
Bilateral tolerancing (also known as symmetric tolerancing) is a method of tolerancing a dimension using equal plus and minus deviations from the nominal dimension.
Unilateral tolerances (also known as asymmetric tolerances) on the other hand specify a deviation in only one direction, either plus or minus, from the specified nominal dimension. Unilateral tolerances may also take the form of plus and plus-plus, minus and minus-minus, or plus or minus some amount and plus or minus a lesser amount.
I'm on that right now i understand the code but don't get how to use it on this one! do you have the answer yet?
