Tolerance is something that is unintended measurement... whereas allowance is one that we give to the material to undergo some process in the future.... For example a cylindrical bore is done undersize to allow honing process in the future,,, and at the final operation we check whether the final size is in the given upper and lower tolerance limits... over tolerance is unintended and we process the material for average size as far as possible.
***********
Mathematically:
Tolerance = |MMC - LMC|
Allowance = MMC(interior) - MMC(exterior)
MMC - Maximum Material Condition; instance of feature dimensions that gives maximum volume, consistent with tolerances.
LMC - Least Material Condition; instance of feature dimensions that gives least volume, consistent with tolerances.
Interior - A hole is an interior feature
Exterior - A shaft is an exterior feature

What is the difference between circularity and cylindricity?
not one circularity that is section of cylindrical surface with in any one of line with in as per tolerance on axis , and cylindrical not one that is entire surface required of with in tolerance according in the axis that is difference
What is the difference between a general and specific tolerance and how can you tell the difference on the drawing?
when reading a blueprint, a general tolerance would apply for all dimensions that are not individually identified. eg, all tolerances are +\- .030" General tolerances are normally found in the information blocks of the blueprint. If for example a tighter tolerance is required, then a specific tolerance is noted for certain areas of the blueprint. These tolerances are normally found beside the affected area.
Why are resistors produced with a certain number of preferred values to a particular tolerance?
it is because the tolerance between tow of the resistors would overlap and that would be pointless.
When a roller bearing needs to pressed onto a shaft what allowance does the shaft have?
When pressing a roller bearing onto a shaft, the shaft typically has a tolerance or allowance that is slightly smaller than the inner diameter of the bearing to ensure a tight fit. This is often referred to as an interference fit, which ensures that the bearing remains securely in place during operation. The specific allowance can vary based on the bearing size and application, but it is crucial to follow manufacturer specifications to avoid damage to either the bearing or the shaft during installation.

Whats the difference between a general and specific tolerance?
In engineering, general tolerance refers to the overall tolerance. A specific tolerance would be noted on a blueprint when an area requires a tolerance which is different than the overall project.
What is the difference between allowance and perquisites?
Allowance are being mentioned in section 10 wheras perquisites in section 17(2) of Income Tax Act, 1961.
What is the difference between the dole and job seekers allowence?
The dole is an alternative name for Jobseeker's Allowance.
What is the difference between patience and tolerance?
Patience is putting up with someone or something, and the willingness to do it. Tolerance is how much you put up with it, and how willing you are to do it. They are related, but not the same thing.
What is the difference between circularity and cylindricity?
not one circularity that is section of cylindrical surface with in any one of line with in as per tolerance on axis , and cylindrical not one that is entire surface required of with in tolerance according in the axis that is difference
