What is the difference between datum dimensioning and chain dimensioning?
Datum dimensioning is where a single reference point is used for all dimensions in a single direction. E.g. If Point A is declared the reference point, then Points B, C, D, etc, will all be measured relative to Point A, not to each other. Chain dimensioning is where each point is measured to the next. E.g. Point B is measured from Point A, Point C is measured from Point B, Point C is measured from Point B, and so on. The problem with chain dimensioning is that each measurement relies on the accuracy of the previous measurement. If there is a tolerance associated with each measurement (+/- X), then the tolerance for each subsequent dimension accumulates and becomes the number of measurements times the tolerance of each measurement (+/- n*X). Since datum dimensioning uses only one reference point, the tolerances cannot accumulate as each measurement is isolated, rather than relying on the accuracy of the previous measurement. Common practice is to only use datum dimensioning in design drawings to ensure greater accuracy over the entire design without requiring tighter tolerances.
What is the difference between A557 chain and CA557 chain?
A557 chain has a curved profile on the link sides. CA557 chain has straight profile on the link sides. Look at Allied-Locke document Catalog 39 to see the differences in link plate profiles.
What is the difference between a polygon and a polyhedron?
polyhedron is often defined as a geometric object with flat faces and straight edges polygon is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). .
How do you adjust the chain on a mojove 250?
The chain on a Kawasaki Mojove 250 ATV is adjusted by removing the chain cover and loosening the retaining bolts. The tensioner can then be turned until the chain reaches the desired tension.
1 chain equals how many feet?
A chain is a very old Linear Measure. 1 chain = 22 yards = 66 feet.
What is chain dimensioning?
It show dimension of given dig. Ex. length meter etc. > chain dimensioning as opposed to datum dimensioning. chain dimensioning: 4 holes in line on a drawing, first hole position dimensioned from the edge, remainder dimensioned from the centre of the previous hole. datum dimensioning: all holes dimensioned from the edge. the cumulative tolerance build up on the chain dimensioning allows for greater overall tolerance build up.

What is the difference between chain printer and band printer?
The difference between a chain printer and a band printer is a chain printer has a chain that the characters are on and a band printer has a band for the characters.

What is the difference between food chain and web chain?
There isn't a big difference between the food chain and food web. This is just a different way of drawing out the same concept.
What is the difference between a mountain range and a mountain chain?
The difference between a mountain range and a mountain chain is that a mountain chain is a row of mountains and a mountain range is lots of mountains in one area.
