Difference between bilateral and unilateral tolerance?

Applying tolerance on both sides of basic size is bilateral tolerance, whereas applying tolerance on one side of basic size is unilateral tolerance Ex: If basic size is 20mm Then bilateral tolerance will be 20+0.02, 20-0.01 Then unilateral tolerance will be 20+0.02, 20-0.01.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
